Scott: /* Tue Jan 6: Intro to Bluewater Sailing - Teresa Augustin, Scott Dynes */

== 2026 Bluewater IAP Shore School ==

Bluewater Winter Sessions are a chance to dive deeper into sailing topics than we're often able to do on the water, and to get to know the program if you're new. The slides from certain sessions are below.

==Tue Jan 6: Intro to Bluewater Sailing - Teresa Augustin, Scott Dynes==
Bluewater Winter Sessions are a chance to dive deeper into sailing topics than we're often able to do on the water, and to get to know the program if you're new.

This session is specifically for sailors new to MIT Bluewater. It's a conversation and Q&A: learn more about how to expand your MIT sailing onto Boston Harbor and beyond.

Note: all Bluewater Winter Sessions will meet in classroom 2-131. For this intro session, just drop in. No sign-up necessary.

Slides from this session: [[File:MIT_IAP_2026_Intro_to_BW_002a_presented.pdf ]]

==Tue Jan 20: Navigation 2 - Electronic Navigation - Scott Dynes, Sandy Wells, Frances Hartwell, Libby Meier==
In this session we will build on the foundation of the previous session, covering the use of electronic navigation (using OpenCPN on e.g. laptops) and chartplotters (e.g. the B&G system on Mashnee). Please bring a laptop to this session with OpenCPN installed and ENC charts for Region 2 (Block Is. to the Canadian border).

In this session we will be going over:

The basics of how to get around OpenCPN

*Using OpenCPN to plan a local and longer trip - tides, currents

*Importing external weather/current information (gribs)

*Exporting routes developed in OpenCPN

*The basics of how to get around the B&G chartplotter

*Important B&G charts and information

*Importing routes developed in OpenCPN

We will practice these skills with a set of in-class exercises.

If you are going to attend this session we urge you to install OpenCPN on your laptop with the ENC charts from Region 2 (Block Is. to the Canadian border) loaded. (See https://www.youtube.com/watch?v=RFrByYYN7Is.)

3 blade Gori feathering propeller. [[File:Mashnee_gori_prop.pdf|manual and instructions for GORI propeller]] and [[File:GORI_Manual-15-16_5-Overdrive-Shaft-A4-3.pdf |more detailed, updated manual]]

==== Folding the Propeller====
Put the gear shift in reverse when the engine is off. This locks the shaft and ensures the propeller folds and does not spin. Then return the lever back into neutral.

==== Normal Ahead ====
If you want to shift from "overdrive" to normal/forward position, the lever will have to be put into neutral when the boat does more than 1 knot ahead until the blades have folded again, then put it in the forward position again.
If the propeller is spinning with the engine in neutral, you must go gently in reverse, while the boat is moving forward. After the propeller has been going in reverse for a few seconds, you can go back to neutral and the propeller will have folded and the shaft stopped. when you back to forward, the propeller will be in normal ahead.
Before leaving the harbor, always check the position of the propeller by means of the boat's tachometer so that the propeller is in the wanted position.
==== Going Astern ====
in the reverse position the blades swing 180 degrees opposite the forward position which ensures the same blade leading edge and profile, resulting in high-efficiency. If the boat has not been used in some time, you should shift cautiously between forward and reversed a few times before sailing in order to clean the teeth of the blades and the gears from fouling.

==== Going Ahead in Overdrive ====
The “Overdrive” function is to be used when motoring at a cruising RPM in fair weather or when motorsailing. Overdrive is a second larger pitch achieved by going forward with the propeller blades in the reverse position. The second higher pitch acts like 5th gear in a car and likewise can increase speed and efficiency.

In order to position the propeller in forward "overdrive" it is necessary to move the boat astern so that the blades are kept in reverse position when the lever is put into forward. Do not try to make the propeller go from forward to "overdrive" position by quick shifts with the lever when the boat is sailing ahead in the water. When in reverse position, the blades have a 20% higher pitch than forward. when you go forward with the propeller in the reverse position, this higher pitch is kept, enabling overdrive.
If you are in standard forward at the higher RPM and want to go into overdrive:
*1. Reduce the engine RPM and put the shift lever into neutral
*2. Go into reverse
*3. Raise the engine RPM several hundred for a few seconds
*4. Reduce the engine RPM and move the shift lever to forward smartly without hesitation You will now be in overdrive.
If you are in overdrive and want to go into standard forward:
*1. Reduce the engine RPM and put the shift lever into neutral
*2. Bump into reverse for a second which stops the shaft immediately
*3. Wait several seconds (shaft should stop rotating), blades fold closed from forward motion and then shift back into forward
*4. This will give you the standard forward position. By bumping into reverse and leaving the engine in neutral for several seconds you are allowing the shaft to stop rotating and the propeller blades to fold closed (action of water flow over the positively geared blades), then when you go back into forward the blades will open in the standard forward position.

Often just after leaving the marina slip you may find that the propeller is in Overdrive. This is due to when backing out of the slip and then shifting the into forward position - while the boat was still moving backwards - the blades will be in the overdrive position. Simply put the shift lever into neutral for a few seconds, make sure the shaft stops turning (bump into reverse for a second) and then back into forward and you will be in the standard forward. Many Gori customers use overdrive for the vast majority of their motoring, only using standard forward in conditions that require great thrust and high RPM such as to power through heavy seas or quickly maneuver.

= Magnetic Compasses =

There is a magnetic compass which is placed in the starboard cockpit locker. When it is deployed it is mounted on a small brass rail at the foot of the companionway.

Note, this compass cannot be trusted. Compasses do not take hard knocks well, and there is no guarantee that its placement is not in a magnetically pathological location. This compass can be used for relative heading hold, e.g. maintaining a number. However, the absolute values are not to be trusted at all. [KDS]

= Galley =

== Stove ==

The stove is an Orico-style alcohol stove. Alcohol does not burn as hot as propane so it takes longer to cook.

To operate the stove, remove the wooden plate and place it above, where the metal underside will serve as a heat deflector.

The top of the stove needs to be open to reveal the metal canister underneath. There is a black rubber disk which seals the canister and keeps the alcohol from evaporating. Remove this.

Ensure that the stove dial is turned to the on position, and then the stove can be lit with a lighter or match.

The stove is extinguished by turning the dial fully off, and then replacing the rubber disk and the wooden cover.

== Ice Box ==
* There is a sump under the ice box to collect the meltwater. This sump can be emptied via the salt water foot pump for the sink if the cross-flow valve underneath the sink is switched. The valve has a pointer on it and the pointer must point up (12:00) for sump drain and to the right (3:00) for the salt water intake.

==== Folding the Propeller====
Put the gear shift in reverse when the engine is off. This locks the shaft and ensures the propeller folds and does not spin. Then return the lever back into neutral.

==== Normal Ahead ====
If you want to shift from "overdrive" to normal/forward position, the lever will have to be put into neutral when the boat does more than 1 knot ahead until the blades have folded again, then put it in the forward position again.
If the propeller is spinning with the engine in neutral, you must go gently in reverse, while the boat is moving forward. After the propeller has been going in reverse for a few seconds, you can go back to neutral and the propeller will have folded and the shaft stopped. when you back to forward, the propeller will be in normal ahead.
Before leaving the harbor, always check the position of the propeller by means of the boat's tachometer so that the propeller is in the wanted position.
==== Going Astern ====
in the reverse position the blades swing 180 degrees opposite the forward position which ensures the same blade leading edge and profile, resulting in high-efficiency. If the boat has not been used in some time, you should shift cautiously between forward and reversed a few times before sailing in order to clean the teeth of the blades and the gears from fouling.

==== Going Ahead in Overdrive ====
The “Overdrive” function is to be used when motoring at a cruising RPM in fair weather or when motorsailing. Overdrive is a second larger pitch achieved by going forward with the propeller blades in the reverse position. The second higher pitch acts like 5th gear in a car and likewise can increase speed and efficiency.

In order to position the propeller in forward "overdrive" it is necessary to move the boat astern so that the blades are kept in reverse position when the lever is put into forward. Do not try to make the propeller go from forward to "overdrive" position by quick shifts with the lever when the boat is sailing ahead in the water. When in reverse position, the blades have a 20% higher pitch than forward. when you go forward with the propeller in the reverse position, this higher pitch is kept, enabling overdrive.
If you are in standard forward at the higher RPM and want to go into overdrive:
*1. Reduce the engine RPM and put the shift lever into neutral
*2. Go into reverse
*3. Raise the engine RPM several hundred for a few seconds
*4. Reduce the engine RPM and move the shift lever to forward smartly without hesitation You will now be in overdrive.
If you are in overdrive and want to go into standard forward:
*1. Reduce the engine RPM and put the shift lever into neutral
*2. Bump into reverse for a second which stops the shaft immediately
*3. Wait several seconds (shaft should stop rotating), blades fold closed from forward motion and then shift back into forward
*4. This will give you the standard forward position. By bumping into reverse and leaving the engine in neutral for several seconds you are allowing the shaft to stop rotating and the propeller blades to fold closed (action of water flow over the positively geared blades), then when you go back into forward the blades will open in the standard forward position.

Often just after leaving the marina slip you may find that the propeller is in Overdrive. This is due to when backing out of the slip and then shifting the into forward position - while the boat was still moving backwards - the blades will be in the overdrive position. Simply put the shift lever into neutral for a few seconds, make sure the shaft stops turning (bump into reverse for a second) and then back into forward and you will be in the standard forward. Many Gori customers use overdrive for the vast majority of their motoring, only using standard forward in conditions that require great thrust and high RPM such as to power through heavy seas or quickly maneuver.

= Magnetic Compasses =

There is a magnetic compass which is placed in the starboard cockpit locker. When it is deployed it is mounted on a small brass rail at the foot of the companionway.

Note, this compass cannot be trusted. Compasses do not take hard knocks well, and there is no guarantee that its placement is not in a magnetically pathological location. This compass can be used for relative heading hold, e.g. maintaining a number. However, the absolute values are not to be trusted at all. [KDS]

= Galley =

== Stove ==

The stove is an Orico-style alcohol stove. Alcohol does not burn as hot as propane so it takes longer to cook.

To operate the stove, remove the wooden plate and place it above, where the metal underside will serve as a heat deflector.

The top of the stove needs to be open to reveal the metal canister underneath. There is a black rubber disk which seals the canister and keeps the alcohol from evaporating. Remove this.

Ensure that the stove dial is turned to the on position, and then the stove can be lit with a lighter or match.

The stove is extinguished by turning the dial fully off, and then replacing the rubber disk and the wooden cover.

== Ice Box ==
* There is a sump under the ice box to collect the meltwater. This sump can be emptied via the salt water foot pump for the sink if the cross-flow valve underneath the sink is switched. The valve has a pointer on it and the pointer must point up (12:00) for sump drain and to the right (3:00) for the salt water intake.

3 blade Gori feathering propeller. [[File:Mashnee_gori_prop.pdf|manual and instructions for GORI propeller]] and [[File:GORI_Manual-15-16_5-Overdrive-Shaft-A4-3.pdf |more detailed, updated manual]]

==== Folding the Propeller====
Put the gear shift in reverse when the engine is off. This locks the shaft and ensures the propeller folds and does not spin. Then return the lever back into neutral.

==== Normal Ahead ====
If you want to shift from "overdrive" to normal/forward position, the lever will have to be put into neutral when the boat does more than 1 knot ahead until the blades have folded again, then put it in the forward position again.
If the propeller is spinning with the engine in neutral, you must go gently in reverse, while the boat is moving forward. After the propeller has been going in reverse for a few seconds, you can go back to neutral and the propeller will have folded and the shaft stopped. when you back to forward, the propeller will be in normal ahead.
Before leaving the harbor, always check the position of the propeller by means of the boat's tachometer so that the propeller is in the wanted position.
==== Going Astern ====
in the reverse position the blades swing 180 degrees opposite the forward position which ensures the same blade leading edge and profile, resulting in high-efficiency. If the boat has not been used in some time, you should shift cautiously between forward and reversed a few times before sailing in order to clean the teeth of the blades and the gears from fouling.

==== Going Ahead in Overdrive ====
The “Overdrive” function is to be used when motoring at a cruising RPM in fair weather or when motorsailing. Overdrive is a second larger pitch achieved by going forward with the propeller blades in the reverse position. The second higher pitch acts like 5th gear in a car and likewise can increase speed and efficiency.

In order to position the propeller in forward "overdrive" it is necessary to move the boat astern so that the blades are kept in reverse position when the lever is put into forward. Do not try to make the propeller go from forward to "overdrive" position by quick shifts with the lever when the boat is sailing ahead in the water. When in reverse position, the blades have a 20% higher pitch than forward. when you go forward with the propeller in the reverse position, this higher pitch is kept, enabling overdrive.
If you are in standard forward at the higher RPM and want to go into overdrive:
*1. Reduce the engine RPM and put the shift lever into neutral
*2. Go into reverse
*3. Raise the engine RPM several hundred for a few seconds
*4. Reduce the engine RPM and move the shift lever to forward smartly without hesitation You will now be in overdrive.
If you are in overdrive and want to go into standard forward:
*1. Reduce the engine RPM and put the shift lever into neutral
*2. Bump into reverse for a second which stops the shaft immediately
*3. Wait several seconds (shaft should stop rotating), blades fold closed from forward motion and then shift back into forward
*4. This will give you the standard forward position. By bumping into reverse and leaving the engine in neutral for several seconds you are allowing the shaft to stop rotating and the propeller blades to fold closed (action of water flow over the positively geared blades), then when you go back into forward the blades will open in the standard forward position.

Often just after leaving the marina slip you may find that the propeller is in Overdrive. This is due to when backing out of the slip and then shifting the into forward position - while the boat was still moving backwards - the blades will be in the overdrive position. Simply put the shift lever into neutral for a few seconds, make sure the shaft stops turning (bump into reverse for a second) and then back into forward and you will be in the standard forward. Many Gori customers use overdrive for the vast majority of their motoring, only using standard forward in conditions that require great thrust and high RPM such as to power through heavy seas or quickly maneuver.

By bumping into reverse and leaving the engine in neutral for several seconds you are allowing the shaft to stop rotating and the propeller blades to fold closed (action of water flow over the positively geared blades), then when you go back into forward the blades will open in the standard forward position.

Often just after leaving the marina slip you may find that the propeller is in Overdrive. This is due to when backing out of the slip and then shifting the into forward position - while the boat was still moving backwards - the blades will be in the overdrive position. Simply put the shift lever into neutral for a few seconds, make sure the shaft stops turning (bump into reverse for a second) and then back into forward and you will be in the standard forward. Many Gori customers use overdrive for the vast majority of their motoring, only using standard forward in conditions that require great thrust and high RPM such as to power through heavy seas or quickly maneuver.

= Magnetic Compasses =

There is a magnetic compass which is placed in the starboard cockpit locker. When it is deployed it is mounted on a small brass rail at the foot of the companionway.

Note, this compass cannot be trusted. Compasses do not take hard knocks well, and there is no guarantee that its placement is not in a magnetically pathological location. This compass can be used for relative heading hold, e.g. maintaining a number. However, the absolute values are not to be trusted at all. [KDS]

= Galley =

== Stove ==

The stove is an Orico-style alcohol stove. Alcohol does not burn as hot as propane so it takes longer to cook.

To operate the stove, remove the wooden plate and place it above, where the metal underside will serve as a heat deflector.

The top of the stove needs to be open to reveal the metal canister underneath. There is a black rubber disk which seals the canister and keeps the alcohol from evaporating. Remove this.

Ensure that the stove dial is turned to the on position, and then the stove can be lit with a lighter or match.

The stove is extinguished by turning the dial fully off, and then replacing the rubber disk and the wooden cover.

== Ice Box ==
* There is a sump under the ice box to collect the meltwater. This sump can be emptied via the salt water foot pump for the sink if the cross-flow valve underneath the sink is switched. The valve has a pointer on it and the pointer must point up (12:00) for sump drain and to the right (3:00) for the salt water intake.

=== Transmission ===

=== Propeller ===

3 blade Gori feathering propeller. [[File:Mashnee_gori_prop.pdf|manual and instructions for GORI propeller]] and [[File:GORI_Manual-15-16_5-Overdrive-Shaft-A4-3.pdf |more detailed, updated manual]]

==== Folding the Propeller====
Put the gear shift in reverse when the engine is off. This locks the shaft and ensures the propeller folds and does not spin. Then return the lever back into neutral.

==== Normal Ahead ====
If you want to shift from "overdrive" to normal/forward position, the lever will have to be put into neutral when the boat does more than 1 knot ahead until the blades have folded again, then put it in the forward position again.
If the propeller is spinning with the engine in neutral, you must go gently in reverse, while the boat is moving forward. After the propeller has been going in reverse for a few seconds, you can go back to neutral and the propeller will have folded and the shaft stopped. when you back to forward, the propeller will be in normal ahead.
Before leaving the harbor, always check the position of the propeller by means of the boat's tachometer so that the propeller is in the wanted position.
==== Going Astern ====
in the reverse position the blades swing 180 degrees opposite the forward position which ensures the same blade leading edge and profile, resulting in high-efficiency. If the boat has not been used in some time, you should shift cautiously between forward and reversed a few times before sailing in order to clean the teeth of the blades and the gears from fouling.

==== Going Ahead in Overdrive ====
The “Overdrive” function is to be used when motoring at a cruising RPM in fair weather or when motorsailing. Overdrive is a second larger pitch achieved by going forward with the propeller blades in the reverse position. The second higher pitch acts like 5th gear in a car and likewise can increase speed and efficiency.

In order to position the propeller in forward "overdrive" it is necessary to move the boat astern so that the blades are kept in reverse position when the lever is put into forward. Do not try to make the propeller go from forward to "overdrive" position by quick shifts with the lever when the boat is sailing ahead in the water. When in reverse position, the blades have a 20% higher pitch than forward. when you go forward with the propeller in the reverse position, this higher pitch is kept, enabling overdrive.
If you are in standard forward at the higher RPM and want to go into overdrive:
*1. Reduce the engine RPM and put the shift lever into neutral
*2. Go into reverse
*3. Raise the engine RPM several hundred for a few seconds
*4. Reduce the engine RPM and move the shift lever to forward smartly without hesitation You will now be in overdrive.
If you are in overdrive and want to go into standard forward:
*1. Reduce the engine RPM and put the shift lever into neutral
*2. Bump into reverse for a second which stops the shaft immediately
*3. Wait several seconds (shaft should stop rotating), blades fold closed from forward motion and then shift back into forward
*4. This will give you the standard forward position. By bumping into reverse and leaving the engine in neutral for several seconds you are allowing the shaft to stop rotating and the propeller blades to fold closed (action of water flow over the positively geared blades), then when you go back into forward the blades will open in the standard forward position.

Often just after leaving the marina slip you may find that the propeller is in Overdrive. This is due to when backing out of the slip and then shifting the into forward position - while the boat was still moving backwards - the blades will be in the overdrive position. Simply put the shift lever into neutral for a few seconds, make sure the shaft stops turning (bump into reverse for a second) and then back into forward and you will be in the standard forward. Many Gori customers use overdrive for the vast majority of their motoring, only using standard forward in conditions that require great thrust and high RPM such as to power through heavy seas or quickly maneuver.

== 2025 Bluewater IAP Shore School ==

Bluewater Winter Sessions are a chance to dive deeper into sailing topics than we're often able to do on the water, and to get to know the program if you're new. The slides from certain sessions are below.

==Tue Jan 3: Intro to Bluewater Sailing - Teresa Augustin, Scott Dynes==
Bluewater Winter Sessions are a chance to dive deeper into sailing topics than we're often able to do on the water, and to get to know the program if you're new.

This session is specifically for sailors new to MIT Bluewater. It's a conversation and Q&A: learn more about how to expand your MIT sailing onto Boston Harbor and beyond.

Note: all Bluewater Winter Sessions will meet in classroom 2-131. You can just drop in. No sing-up necessary.

Slides from this session: [[File:MIT_IAP_2025_Intro_to_BW_007a_presented.pdf]]

==Thu Jan 16: Weather and Electronic Navigation - Scott Dynes and Sandy Wells==

This session is a combination of weather and electronic navigation.

In weatyher, we will be going over:

* Where does the weather come from?
* Fronts and air masses
* Cloud types
* Wind, waves, and warnings
* What can you tell from looking at the skies and barometer?
* Wave heights (wind and fetches)
as well as weather forecasting products and models available online and get usable electronic copies of these products (gribs).

Next, we will be talking about how to use those gribs in a bluewater setting, which is best done using an electronic chartplotter. We will not be demoing the B&G system we have on Mashnee, but will be demoing OpenCPN, which is available for laptiops and android devices like tablets and smartphones. If attendees want to follow along in class, I suggest they install OpenCPN on their laptop with a few charts (see https://www.youtube.com/watch?v=RFrByYYN7Is). Charts from Region 2 (Block Is. to the Canadian border) should be adequate.

We hope to cover the following:

* Quick overview of OpenCPN
* Loading and updating charts
* Requesting and importing Gribs
* Using the routing plugin with weather and current forecasts

== Steering ==

=== Helm ===

* The steering wheel is trapped by the fiberglass cover in the center of the cockpit. Remove this cover to remove the steering wheel.
* The emergency tiller is a long steel bar inserted into a square hole beneath an inspection portal in the fiberglass cover aft of the helm. The tiller is kept in the starboard lazarette.

=== Rudder ===

* When hauled in Nov 2011, the rudder was saturated with water. 4 holes were drilled to drain it over the winter, then plugged in May 2012.
* The rudder was pulled Dec 2011 and the shaft repacked. Prior to this time there was a steady trickle of water entering the boat from the rudder post.

== Thru-Hulls ==

As delivered to MIT in August 2011, X-Dimension had 11 thru-hulls. 
After Winter 2011/2012 refurb, the thru-hulls are:

* port v-berth 1.5" - blackwater out
* port forward of keel 1" - greywater out
* port mid-keel 0.75" - toilet in
* stbd mid-keel 0.75" - galley seawater
* port mid-keel 2" - speed impeller
* stbd mid-keel 2" - depth transceiver (epoxied in place)
* stbd aft of keel 1.5" - galley greywater out
* stbd mid cockpit 1" - engine in
* stbd cockpit 1.5" - scuppers
* port cockpit 1.5" - scuppers
* port cockpit 1/2" at waterline - propane drain

There are two vestigial thru-hulls, one for an impeller and the other for a depth transducer. These are located just aft of the main cabin forward bulkhead, beneath the cabinets.

In June 2013 another thru-hull was added:
* port v-berth 2" - combined speed paddlewheel/depth-sounder/water temperature

== Bilge Pumps ==

There are two electric bilge pumps and two manual bilge pumps. An electric submersible pump is in the central portion of the bilge well. A diaphragm electric pump is in the cabinet beneath the nav station. Float switches for the two electric pumps are located in the bilge well. The diaphragm pump's float switch is in the deepest part of the bilge; it should energize first and keep the bilge dry. The submersible pump's float switch is forward and higher; it should energize if there is an inch or more water in the bilge.

The two electric bilge pumps are connected to the House batteries via the always-on "Bilge Pumps" breaker on [[X-Dimension_systems#Circuit_Breaker_Panel_1|breaker panel #1]]. Individual auto-manual-off controls for the electric pumps are located port of the nav station. Note that the "Bilge Pumps" breaker bypasses the House Battery Switch and the pumps will still operate if the House Battery Switch is off. (See [http://sailing.mit.edu/wikiupload/3/3c/X-dimension_bilge_circuits.pdf X Dimension Bilge Pump Wiring])

The cockpit manual pump is located on the port bulkhead of the cockpit just forward of the helm. The high-volume manual pump is located under the floorboards of the hanging locker behind the nav station, and can be operated without removing the floorboards. The handles for the two manual pumps are stored in the hanging locker behind the nav station. The smaller handle fits the pump in the cockpit, and the longer handle the pump behind the nav station.

All bilge hoses exit the boat starboard of center at the transom.

=== Submersible Electric Bilge Pump ===

* Rule Bilge Pump 1500 Submersible (new in 2012)
* Specs: 12 DC; capacity 1500 GPH '''horizontal flow'''
* Rule-a-Matic float switch in bilge, just forward of the submersible pump
* Rule 3-Way lighted rocker panel switch by nav table

=== Diaphragm Electric Bilge Pump ===

* Jabsco Electric Diaphragm Bilge Pump Model: 34600-0000
* Specs: 12 DC; open flow capacity: 10.8 GPM (648 GPH)
* Rule-a-Matic float switch in deepest part of bilge, aft of the submersible pump
* Rule 3-Way lighted rocker panel switch by nav table

=== Cockpit Manual Pump ===
Located on the port cockpit wall just forward of the wheel.

* Whale Gusher 10
* Repair kit is West Marine part # 255658 OR 135038

Maintained April 2017.

=== High Volume Manual Pump ===

* Edson Gallon-a-Stroke Model 117
* Order parts from Edson http://www.edsonpumps.com/pumps_acc/accessories_pg_02.php
Maintained March 2017.

'''Note:''' the high volume manual pump is operated with the long handle from inside the locker behind the nav station. The pump itself is underneath the floorboards in that locker; the handle is inserted into the pump through a cut-out in the floorboards on the starboard side of the locker (to your left when looking into the locker). The cutout may be covered by stored items, such as PFDs, which must be removed to access the pump.

=== Strum Boxes ===

* Strum boxes are 1 1/2" West Marine part # 100729, Whale mfg. part # SB5865

== Head ==

The head is a hand-operated marine toilet unit connected to a 25 gallon expanding holding tank. The output from the toilet goes into the holding tank. From the holding tank there are two hoses, one to a pump-out fitting on the deck, the other to a thru-hull under the forward cabin sink.

The forward facing panel beneath the sink in the forward cabin can be removed for access to the thru-hull valve.

The seawater in thru-hull is located port of center under the main cabin floorboards, just aft of the mast. A small mesh strainer is located inline soon after the thru-hull valve.

The toilet is Jabsco model 29090-2000 (compact bowl & seat).

= Electrical =

== 12-volt ==

=== Batteries ===

There are two independent sets of batteries on the boat. The "Engine" battery (or "Starter Battery") is used for starting the engine. The "House" batteries supply power to most of the rest of the electrical equipment onboard.

The House batteries are charged by the alternator. The Engine battery is charged via the Balmar Duo Charge, mounted on the bulkhead above and just forward of the House batteries. A solar panel was installed in 2015 to trickle-charge the house batteries.

==== Engine Battery ====

The Engine Battery is a marine dual-purpose AGM battery. The battery is located in the port lazarette, next to the water heater, and under the propane tank.

The Engine battery is isolated by the Engine Battery Switch, located alongside the circuit breakers above the galley sink. The Engine Battery Switch is an on/off switch, located by the circuit breaker panels above the galley sink.

When the Engine Battery Switch is on, power is connected to the starter motor and to the "Ignition Switch" on the binnacle in the cockpit through the always-on 50 amp "Engine" breaker above the galley sink. The Ignition Switch on the binnacle powers the following circuits:

* Starter button on binnacle (connected to starter solenoid)
* Balmar charging regulator
* Engine instruments in cockpit instrument panel
* Engine temperature sensors, oil pressure sensor and alarm buzzer
* Electric inline Fuel Pump located under port settee, just aft of the fuel tank

The Engine Battery Switch should be switched to OFF when leaving the boat.

==== House Batteries ====

The House battery bank consists of two Lifeline GPL-31T deep-cycle marine AGM batteries, tied together in parallel. This battery bank is located in the starboard lazarette, just aft of a bulkhead that separates the lazarette from the main cabin. The House battery compartment is usually covered by a white wooden tray that contains winch handles.

The House battery bank is isolated by the House Battery Switch, located alongside the circuit breakers above the galley sink.
The House Battery Switch is a four-way switch located by the circuit breaker panels above the galley sink. During normal operation of the boat, the House Battery Switch should be switched to the "House" position. This allows the house battery bank to be charged by the engine, and to power the various 12-volt devices through the breakers above the galley sink.

The House Battery Switch should be switched to "OFF" when leaving the boat.

The two additional positions on the House Battery Switch will enable parallel use of the House battery bank and the Engine battery, and should only be used in case of emergency. (See [http://sailing.mit.edu/wiki/index.php/Standard_operational_procedures#Emergency_Battery_Operations Emergency Battery Operations]) Note that the Engine Battery Switch must be ON in order to use the House Battery Switch as an emergency parallel switch.

=== Solar Charging ===

A 55-watt '''Ganz GSP-55 solar panel''' is installed on the v-berth hatch. The cable snakes through the dorade box into the head, then along the port wiring conduit. It connects to a '''Morningstar SunSaver MPPT solar controller''' which charges the House battery bank directly (not through the House Battery Switch).

=== Circuit Breaker Panels ===

As of September 2016, there are four circuit breaker panels above the galley sink, and one panel in the cockpit.

*'''Note''': Any circuits that are not currently connected will be labeled "N/C" with blue tape at the circuit breaker.

==== Circuit Breaker Panel 4 ====

As of September 2016, this Breaker panel is not being used. Some of the breakers may be used for other circuits in the future. Some of the space on the panel may also be used for ammeters in the future.

==== Nav Lights Fuse Panel ====

The dark grey plastic panel in the cockpit, starboard of the wheel, is a Blue Sea Systems "[http://bluesea.com/category/16/products/4306 WeatherDeck Waterproof Fuse Panel]". The navigation lights on the boat are controlled through this six-position panel.

Power to this panel is supplied by the "Navigation Lights Master" circuit breaker on the control panels above the galley sink. Each of the six circuits is protected by an internal blade-type fuse. When power is supplied to the panel, and the corresponding fuses are not blown, then the circuit indicator labels will glow red. When each circuit is switched on, then the label will glow green. If the label does not glow, then the fuse is probably blown. Please see the instruction manual for fuse replacement.

There are two vestigial thru-hulls, one for an impeller and the other for a depth transducer. These are located just aft of the main cabin forward bulkhead, beneath the cabinets.

In June 2013 another thru-hull was added:
* port v-berth 2" - combined speed paddlewheel/depth-sounder/water temperature

== Bilge Pumps ==

There are two electric bilge pumps and two manual bilge pumps. An electric submersible pump is in the central portion of the bilge well. A diaphragm electric pump is in the cabinet beneath the nav station. Float switches for the two electric pumps are located in the bilge well. The diaphragm pump's float switch is in the deepest part of the bilge; it should energize first and keep the bilge dry. The submersible pump's float switch is forward and higher; it should energize if there is an inch or more water in the bilge.

The two electric bilge pumps are connected to the House batteries via the always-on "Bilge Pumps" breaker on [[X-Dimension_systems#Circuit_Breaker_Panel_1|breaker panel #1]]. Individual auto-manual-off controls for the electric pumps are located port of the nav station. Note that the "Bilge Pumps" breaker bypasses the House Battery Switch and the pumps will still operate if the House Battery Switch is off. (See [http://sailing.mit.edu/wikiupload/3/3c/X-dimension_bilge_circuits.pdf X Dimension Bilge Pump Wiring])

The cockpit manual pump is located on the port bulkhead of the cockpit just forward of the helm. The high-volume manual pump is located under the floorboards of the hanging locker behind the nav station, and can be operated without removing the floorboards. The handles for the two manual pumps are stored in the hanging locker behind the nav station. The smaller handle fits the pump in the cockpit, and the longer handle the pump behind the nav station.

All bilge hoses exit the boat starboard of center at the transom.

'''Note:''' the high volume manual pump is operated with the long handle from inside the locker behind the nav station. The pump itself is underneath the floorboards in that locker; the handle is inserted into the pump through a cut-out in the floorboards on the starboard side of the locker (to your left when looking into the locker). The cutout may be covered by stored items, such as PFDs, which must be removed to access the pump.

=== Strum Boxes ===

* Strum boxes are 1 1/2" West Marine part # 100729, Whale mfg. part # SB5865

== Head ==

The head is a hand-operated marine toilet unit connected to a 25 gallon expanding holding tank. The output from the toilet goes into the holding tank. From the holding tank there are two hoses, one to a pump-out fitting on the deck, the other to a thru-hull under the forward cabin sink.

The forward facing panel beneath the sink in the forward cabin can be removed for access to the thru-hull valve.

The seawater in thru-hull is located port of center under the main cabin floorboards, just aft of the mast. A small mesh strainer is located inline soon after the thru-hull valve.

The toilet is Jabsco model 29090-2000 (compact bowl & seat).

= Electrical =

== 12-volt ==

=== Batteries ===

There are two independent sets of batteries on the boat. The "Engine" battery (or "Starter Battery") is used for starting the engine. The "House" batteries supply power to most of the rest of the electrical equipment onboard.

The House batteries are charged by the alternator. The Engine battery is charged via the Balmar Duo Charge, mounted on the bulkhead above and just forward of the House batteries. A solar panel was installed in 2015 to trickle-charge the house batteries.

==== Engine Battery ====

The Engine Battery is a marine dual-purpose AGM battery. The battery is located in the port lazarette, next to the water heater, and under the propane tank.

The Engine battery is isolated by the Engine Battery Switch, located alongside the circuit breakers above the galley sink. The Engine Battery Switch is an on/off switch, located by the circuit breaker panels above the galley sink.

When the Engine Battery Switch is on, power is connected to the starter motor and to the "Ignition Switch" on the binnacle in the cockpit through the always-on 50 amp "Engine" breaker above the galley sink. The Ignition Switch on the binnacle powers the following circuits:

* Starter button on binnacle (connected to starter solenoid)
* Balmar charging regulator
* Engine instruments in cockpit instrument panel
* Engine temperature sensors, oil pressure sensor and alarm buzzer
* Electric inline Fuel Pump located under port settee, just aft of the fuel tank

The Engine Battery Switch should be switched to OFF when leaving the boat.

==== House Batteries ====

The House battery bank consists of two Lifeline GPL-31T deep-cycle marine AGM batteries, tied together in parallel. This battery bank is located in the starboard lazarette, just aft of a bulkhead that separates the lazarette from the main cabin. The House battery compartment is usually covered by a white wooden tray that contains winch handles.

The House battery bank is isolated by the House Battery Switch, located alongside the circuit breakers above the galley sink.
The House Battery Switch is a four-way switch located by the circuit breaker panels above the galley sink. During normal operation of the boat, the House Battery Switch should be switched to the "House" position. This allows the house battery bank to be charged by the engine, and to power the various 12-volt devices through the breakers above the galley sink.

The House Battery Switch should be switched to "OFF" when leaving the boat.

The two additional positions on the House Battery Switch will enable parallel use of the House battery bank and the Engine battery, and should only be used in case of emergency. (See [http://sailing.mit.edu/wiki/index.php/Standard_operational_procedures#Emergency_Battery_Operations Emergency Battery Operations]) Note that the Engine Battery Switch must be ON in order to use the House Battery Switch as an emergency parallel switch.

=== Solar Charging ===

A 55-watt '''Ganz GSP-55 solar panel''' is installed on the v-berth hatch. The cable snakes through the dorade box into the head, then along the port wiring conduit. It connects to a '''Morningstar SunSaver MPPT solar controller''' which charges the House battery bank directly (not through the House Battery Switch).

=== Circuit Breaker Panels ===

As of September 2016, there are four circuit breaker panels above the galley sink, and one panel in the cockpit.

*'''Note''': Any circuits that are not currently connected will be labeled "N/C" with blue tape at the circuit breaker.

==== Circuit Breaker Panel 4 ====

As of September 2016, this Breaker panel is not being used. Some of the breakers may be used for other circuits in the future. Some of the space on the panel may also be used for ammeters in the future.

==== Nav Lights Fuse Panel ====

The dark grey plastic panel in the cockpit, starboard of the wheel, is a Blue Sea Systems "[http://bluesea.com/category/16/products/4306 WeatherDeck Waterproof Fuse Panel]". The navigation lights on the boat are controlled through this six-position panel.

Power to this panel is supplied by the "Navigation Lights Master" circuit breaker on the control panels above the galley sink. Each of the six circuits is protected by an internal blade-type fuse. When power is supplied to the panel, and the corresponding fuses are not blown, then the circuit indicator labels will glow red. When each circuit is switched on, then the label will glow green. If the label does not glow, then the fuse is probably blown. Please see the instruction manual for fuse replacement.

* When hauled in Nov 2011, the rudder was saturated with water. 4 holes were drilled to drain it over the winter, then plugged in May 2012.
* The rudder was pulled Dec 2011 and the shaft repacked. Prior to this time there was a steady trickle of water entering the boat from the rudder post.

== Thru-Hulls ==

As delivered to MIT in August 2011, X-Dimension had 11 thru-hulls. 
After Winter 2011/2012 refurb, the thru-hulls are:

* port v-berth 1.5" - blackwater out
* port forward of keel 1" - greywater out
* port mid-keel 0.75" - toilet in
* stbd mid-keel 0.75" - galley seawater
* port mid-keel 2" - speed impeller
* stbd mid-keel 2" - depth transceiver (epoxied in place)
* stbd aft of keel 1.5" - galley greywater out
* stbd mid cockpit 1" - engine in
* stbd cockpit 1.5" - scuppers
* port cockpit 1.5" - scuppers
* port cockpit 1/2" at waterline - propane drain

There are two vestigial thru-hulls, one for an impeller and the other for a depth transducer. These are located just aft of the main cabin forward bulkhead, beneath the cabinets.

In June 2013 another thru-hull was added:
* port v-berth 2" - combined speed paddlewheel/depth-sounder/water temperature

== Bilge Pumps ==

There are two electric bilge pumps and two manual bilge pumps. An electric submersible pump is in the central portion of the bilge well. A diaphragm electric pump is in the cabinet beneath the nav station. Float switches for the two electric pumps are located in the bilge well. The diaphragm pump's float switch is in the deepest part of the bilge; it should energize first and keep the bilge dry. The submersible pump's float switch is forward and higher; it should energize if there is an inch or more water in the bilge.

The two electric bilge pumps are connected to the House batteries via the always-on "Bilge Pumps" breaker on [[X-Dimension_systems#Circuit_Breaker_Panel_1|breaker panel #1]]. Individual auto-manual-off controls for the electric pumps are located port of the nav station. Note that the "Bilge Pumps" breaker bypasses the House Battery Switch and the pumps will still operate if the House Battery Switch is off. (See [http://sailing.mit.edu/wikiupload/3/3c/X-dimension_bilge_circuits.pdf X Dimension Bilge Pump Wiring])

The cockpit manual pump is located on the port bulkhead of the cockpit just forward of the helm. The high-volume manual pump is located under the floorboards of the hanging locker behind the nav station, and can be operated without removing the floorboards. The handles for the two manual pumps are stored in the hanging locker behind the nav station. The smaller handle fits the pump in the cockpit, and the longer handle the pump behind the nav station.

All bilge hoses exit the boat starboard of center at the transom.

Maintained March 2017.

'''Note:''' the high volume manual pump is operated with the long handle from inside the locker behind the nav station. The pump itself is underneath the floorboards in that locker; the handle is inserted into the pump through a cut-out in the floorboards on the starboard side of the locker (to your left when looking into the locker). The cutout may be covered by stored items, such as PFDs, which must be removed to access the pump.

=== Strum Boxes ===

* Strum boxes are 1 1/2" West Marine part # 100729, Whale mfg. part # SB5865

== Head ==

The head is a hand-operated marine toilet unit connected to a 25 gallon expanding holding tank. The output from the toilet goes into the holding tank. From the holding tank there are two hoses, one to a pump-out fitting on the deck, the other to a thru-hull under the forward cabin sink.

The forward facing panel beneath the sink in the forward cabin can be removed for access to the thru-hull valve.

The seawater in thru-hull is located port of center under the main cabin floorboards, just aft of the mast. A small mesh strainer is located inline soon after the thru-hull valve.

The toilet is Jabsco model 29090-2000 (compact bowl & seat).

= Electrical =

== 12-volt ==

=== Batteries ===

There are two independent sets of batteries on the boat. The "Engine" battery (or "Starter Battery") is used for starting the engine. The "House" batteries supply power to most of the rest of the electrical equipment onboard.

The House batteries are charged by the alternator. The Engine battery is charged via the Balmar Duo Charge, mounted on the bulkhead above and just forward of the House batteries. A solar panel was installed in 2015 to trickle-charge the house batteries.

==== Engine Battery ====

The Engine Battery is a marine dual-purpose AGM battery. The battery is located in the port lazarette, next to the water heater, and under the propane tank.

The Engine battery is isolated by the Engine Battery Switch, located alongside the circuit breakers above the galley sink. The Engine Battery Switch is an on/off switch, located by the circuit breaker panels above the galley sink.

When the Engine Battery Switch is on, power is connected to the starter motor and to the "Ignition Switch" on the binnacle in the cockpit through the always-on 50 amp "Engine" breaker above the galley sink. The Ignition Switch on the binnacle powers the following circuits:

* Starter button on binnacle (connected to starter solenoid)
* Balmar charging regulator
* Engine instruments in cockpit instrument panel
* Engine temperature sensors, oil pressure sensor and alarm buzzer
* Electric inline Fuel Pump located under port settee, just aft of the fuel tank

The Engine Battery Switch should be switched to OFF when leaving the boat.

==== House Batteries ====

The House battery bank consists of two Lifeline GPL-31T deep-cycle marine AGM batteries, tied together in parallel. This battery bank is located in the starboard lazarette, just aft of a bulkhead that separates the lazarette from the main cabin. The House battery compartment is usually covered by a white wooden tray that contains winch handles.

The House battery bank is isolated by the House Battery Switch, located alongside the circuit breakers above the galley sink.
The House Battery Switch is a four-way switch located by the circuit breaker panels above the galley sink. During normal operation of the boat, the House Battery Switch should be switched to the "House" position. This allows the house battery bank to be charged by the engine, and to power the various 12-volt devices through the breakers above the galley sink.

The House Battery Switch should be switched to "OFF" when leaving the boat.

The two additional positions on the House Battery Switch will enable parallel use of the House battery bank and the Engine battery, and should only be used in case of emergency. (See [http://sailing.mit.edu/wiki/index.php/Standard_operational_procedures#Emergency_Battery_Operations Emergency Battery Operations]) Note that the Engine Battery Switch must be ON in order to use the House Battery Switch as an emergency parallel switch.

=== Solar Charging ===

A 55-watt '''Ganz GSP-55 solar panel''' is installed on the v-berth hatch. The cable snakes through the dorade box into the head, then along the port wiring conduit. It connects to a '''Morningstar SunSaver MPPT solar controller''' which charges the House battery bank directly (not through the House Battery Switch).

=== Circuit Breaker Panels ===

As of September 2016, there are four circuit breaker panels above the galley sink, and one panel in the cockpit.

*'''Note''': Any circuits that are not currently connected will be labeled "N/C" with blue tape at the circuit breaker.

==== Circuit Breaker Panel 4 ====

As of September 2016, this Breaker panel is not being used. Some of the breakers may be used for other circuits in the future. Some of the space on the panel may also be used for ammeters in the future.

==== Nav Lights Fuse Panel ====

The dark grey plastic panel in the cockpit, starboard of the wheel, is a Blue Sea Systems "[http://bluesea.com/category/16/products/4306 WeatherDeck Waterproof Fuse Panel]". The navigation lights on the boat are controlled through this six-position panel.

Power to this panel is supplied by the "Navigation Lights Master" circuit breaker on the control panels above the galley sink. Each of the six circuits is protected by an internal blade-type fuse. When power is supplied to the panel, and the corresponding fuses are not blown, then the circuit indicator labels will glow red. When each circuit is switched on, then the label will glow green. If the label does not glow, then the fuse is probably blown. Please see the instruction manual for fuse replacement.

[[IMAGE:XD_compressor_2.jpg|thumb=XD_compressor_2_tn.jpg|right|Fridge Compressor (top)]]
[[IMAGE:XD_compressor_rear.jpg|thumb=XD_compressor_rear_tn.jpg|right|Compressor rear label]]

The refrigerator / ice box is located beneath the galley counter and can be accessed via two hinged hatches. There is a shelf in the refrigerator compartment that will accommodate ice blocks.

The refrigerator compressor is made by '''Alder/Barbour'''. The exact model is unknown but appears similar to the '''ColdMachine''' model.

The compressor runs on the 12V house battery and is located in the starboard lazarette outboard of the house battery box. The compressor is powered by a 15A breaker on breaker panel 2 above the galley sink. A thermostat in the ice box controls operation of the compressor.

The compressor has two blade type fuses located at the outboard aft corner:
* 15A Main
* 5A Fans

A diagnostic LED is on the rear panel; the cadence of the LED's flashing indicates the specific problem with the compressor.

=== Helm ===

* The steering wheel is trapped by the fiberglass cover in the center of the cockpit. Remove this cover to remove the steering wheel.
* The emergency tiller is a long steel bar inserted into a square hole beneath an inspection portal in the fiberglass cover aft of the helm. The tiller is kept in the starboard lazarette.

=== Rudder ===

* When hauled in Nov 2011, the rudder was saturated with water. 4 holes were drilled to drain it over the winter, then plugged in May 2012.
* The rudder was pulled Dec 2011 and the shaft repacked. Prior to this time there was a steady trickle of water entering the boat from the rudder post.

== Thru-Hulls ==

As delivered to MIT in August 2011, X-Dimension had 11 thru-hulls. 
After Winter 2011/2012 refurb, the thru-hulls are:

* port v-berth 1.5" - blackwater out
* port forward of keel 1" - greywater out
* port mid-keel 0.75" - toilet in
* stbd mid-keel 0.75" - galley seawater
* port mid-keel 2" - speed impeller
* stbd mid-keel 2" - depth transceiver (epoxied in place)
* stbd aft of keel 1.5" - galley greywater out
* stbd mid cockpit 1" - engine in
* stbd cockpit 1.5" - scuppers
* port cockpit 1.5" - scuppers
* port cockpit 1/2" at waterline - propane drain

There are two vestigial thru-hulls, one for an impeller and the other for a depth transducer. These are located just aft of the main cabin forward bulkhead, beneath the cabinets.

In June 2013 another thru-hull was added:
* port v-berth 2" - combined speed paddlewheel/depth-sounder/water temperature

== Bilge Pumps ==

There are two electric bilge pumps and two manual bilge pumps. An electric submersible pump is in the central portion of the bilge well. A diaphragm electric pump is in the cabinet beneath the nav station. Float switches for the two electric pumps are located in the bilge well. The diaphragm pump's float switch is in the deepest part of the bilge; it should energize first and keep the bilge dry. The submersible pump's float switch is forward and higher; it should energize if there is an inch or more water in the bilge.

The two electric bilge pumps are connected to the House batteries via the always-on "Bilge Pumps" breaker on [[X-Dimension_systems#Circuit_Breaker_Panel_1|breaker panel #1]]. Individual auto-manual-off controls for the electric pumps are located port of the nav station. Note that the "Bilge Pumps" breaker bypasses the House Battery Switch and the pumps will still operate if the House Battery Switch is off. (See [http://sailing.mit.edu/wikiupload/3/3c/X-dimension_bilge_circuits.pdf X Dimension Bilge Pump Wiring])

The cockpit manual pump is located on the port bulkhead of the cockpit just forward of the helm. The high-volume manual pump is located under the floorboards of the hanging locker behind the nav station, and can be operated without removing the floorboards. The handles for the two manual pumps are stored in the hanging locker behind the nav station. The smaller handle fits the pump in the cockpit, and the longer handle the pump behind the nav station.

All bilge hoses exit the boat starboard of center at the transom.

=== Submersible Electric Bilge Pump ===

* Rule Bilge Pump 1500 Submersible (new in 2012)
* Specs: 12 DC; capacity 1500 GPH '''horizontal flow'''
* Rule-a-Matic float switch in bilge, just forward of the submersible pump
* Rule 3-Way lighted rocker panel switch by nav table

* Jabsco Electric Diaphragm Bilge Pump Model: 34600-0000
* Specs: 12 DC; open flow capacity: 10.8 GPM (648 GPH)
* Rule-a-Matic float switch in deepest part of bilge, aft of the submersible pump
* Rule 3-Way lighted rocker panel switch by nav table

=== Cockpit Manual Pump ===
Located on the port cockpit wall just forward of the wheel.

* Whale Gusher 10
* Repair kit is West Marine part # 255658 OR 135038

Maintained April 2017.

=== High Volume Manual Pump ===

* Edson Gallon-a-Stroke Model 117
* Order parts from Edson http://www.edsonpumps.com/pumps_acc/accessories_pg_02.php
Maintained March 2017.

'''Note:''' the high volume manual pump is operated with the long handle from inside the locker behind the nav station. The pump itself is underneath the floorboards in that locker; the handle is inserted into the pump through a cut-out in the floorboards on the starboard side of the locker (to your left when looking into the locker). The cutout may be covered by stored items, such as PFDs, which must be removed to access the pump.

=== Strum Boxes ===

* Strum boxes are 1 1/2" West Marine part # 100729, Whale mfg. part # SB5865

== Head ==

The head is a hand-operated marine toilet unit connected to a 25 gallon expanding holding tank. The output from the toilet goes into the holding tank. From the holding tank there are two hoses, one to a pump-out fitting on the deck, the other to a thru-hull under the forward cabin sink.

The forward facing panel beneath the sink in the forward cabin can be removed for access to the thru-hull valve.

The seawater in thru-hull is located port of center under the main cabin floorboards, just aft of the mast. A small mesh strainer is located inline soon after the thru-hull valve.

The toilet is Jabsco model 29090-2000 (compact bowl & seat).

= Electrical =

== 12-volt ==

=== Batteries ===

There are two independent sets of batteries on the boat. The "Engine" battery (or "Starter Battery") is used for starting the engine. The "House" batteries supply power to most of the rest of the electrical equipment onboard.

The House batteries are charged by the alternator. The Engine battery is charged via the Balmar Duo Charge, mounted on the bulkhead above and just forward of the House batteries. A solar panel was installed in 2015 to trickle-charge the house batteries.

==== Engine Battery ====

The Engine Battery is a marine dual-purpose AGM battery. The battery is located in the port lazarette, next to the water heater, and under the propane tank.

The Engine battery is isolated by the Engine Battery Switch, located alongside the circuit breakers above the galley sink. The Engine Battery Switch is an on/off switch, located by the circuit breaker panels above the galley sink.

When the Engine Battery Switch is on, power is connected to the starter motor and to the "Ignition Switch" on the binnacle in the cockpit through the always-on 50 amp "Engine" breaker above the galley sink. The Ignition Switch on the binnacle powers the following circuits:

* Starter button on binnacle (connected to starter solenoid)
* Balmar charging regulator
* Engine instruments in cockpit instrument panel
* Engine temperature sensors, oil pressure sensor and alarm buzzer
* Electric inline Fuel Pump located under port settee, just aft of the fuel tank

The Engine Battery Switch should be switched to OFF when leaving the boat.

==== House Batteries ====

The House battery bank consists of two Lifeline GPL-31T deep-cycle marine AGM batteries, tied together in parallel. This battery bank is located in the starboard lazarette, just aft of a bulkhead that separates the lazarette from the main cabin. The House battery compartment is usually covered by a white wooden tray that contains winch handles.

The House battery bank is isolated by the House Battery Switch, located alongside the circuit breakers above the galley sink.
The House Battery Switch is a four-way switch located by the circuit breaker panels above the galley sink. During normal operation of the boat, the House Battery Switch should be switched to the "House" position. This allows the house battery bank to be charged by the engine, and to power the various 12-volt devices through the breakers above the galley sink.

The House Battery Switch should be switched to "OFF" when leaving the boat.

The two additional positions on the House Battery Switch will enable parallel use of the House battery bank and the Engine battery, and should only be used in case of emergency. (See [http://sailing.mit.edu/wiki/index.php/Standard_operational_procedures#Emergency_Battery_Operations Emergency Battery Operations]) Note that the Engine Battery Switch must be ON in order to use the House Battery Switch as an emergency parallel switch.

=== Solar Charging ===

A 55-watt '''Ganz GSP-55 solar panel''' is installed on the v-berth hatch. The cable snakes through the dorade box into the head, then along the port wiring conduit. It connects to a '''Morningstar SunSaver MPPT solar controller''' which charges the House battery bank directly (not through the House Battery Switch).

=== Circuit Breaker Panels ===

As of September 2016, there are four circuit breaker panels above the galley sink, and one panel in the cockpit.

*'''Note''': Any circuits that are not currently connected will be labeled "N/C" with blue tape at the circuit breaker.

|}

==== Circuit Breaker Panel 4 ====

As of September 2016, this Breaker panel is not being used. Some of the breakers may be used for other circuits in the future. Some of the space on the panel may also be used for ammeters in the future.

==== Nav Lights Fuse Panel ====

The dark grey plastic panel in the cockpit, starboard of the wheel, is a Blue Sea Systems "[http://bluesea.com/category/16/products/4306 WeatherDeck Waterproof Fuse Panel]". The navigation lights on the boat are controlled through this six-position panel.

Power to this panel is supplied by the "Navigation Lights Master" circuit breaker on the control panels above the galley sink. Each of the six circuits is protected by an internal blade-type fuse. When power is supplied to the panel, and the corresponding fuses are not blown, then the circuit indicator labels will glow red. When each circuit is switched on, then the label will glow green. If the label does not glow, then the fuse is probably blown. Please see the instruction manual for fuse replacement.

** just forward of the stove
** starboard locker, just forward of the mast

Note that there is an 800 watt DC-to-AC inverter on board.

== Anti-Electrolysis ==

* There are two zincs clamped to prompt shaft, new as of March 2016. (Typically replaced each spring.)
* There is an external zinc "guppy" that is deployed at the stern while the boat is on the mooring or at the dock. New as of May 2015.

== Lightning Dissipation ==

* The boat is fully grounded, with a woven copper strip connecting the mast, shrouds, and engine block.
* The mast step is electrically connected to the keel via a grounding strap from the mast step to a keel bolt.
* The only bonding from the grounded systems to salt water is via the propeller shaft via the engine block.

= Electronics =

== Fixed mount GPS ==

* Garmin GPSMap 541 Chartplotter
* mounted in cockpit bulkhead, port of companionway
* antenna is located on the cockpit rail port of center aft of the helm
* communicates with GMI 10 display, wind instruments, depth sounder, and AIS transonder via NMEA 2000 network
* sends position data to VHF500dsc radio (one-way communication) via NMEA 0183 data connection.

== Garmin GMI 10 Sailing Instrument ==

* mounted in cockpit bulkhead, port of companionway
* can display various parameters, such as depth, apparent wind speed and angle, true wind speed and direction, speed over ground, etc.
* Communicates with GPSMap 541, wind instrument & depth sounder via NMEA 2000 network

== Wind ==

* Garmin GWS 10
* senses wind speed and angle
* communicates with GMI 10 display and GPSMap 541 via NMEA 2000 network

== Depth Sounder ==

* Garmin Thru-Hull Intelliducer (depth sounder)
* located starboard of center aft of forward main cabin bulkhead inside of cabinet
* communicates with GMI 10 display and GPSMap 541 via NMEA 2000 network

== NMEA 2000 network ==

The NMEA 2000 network on ''X Dimension'' entirely consists of instruments, cables and connectors manufactured by Garmin. All connectors are NMEA 2000 "Micro" connectors. The network consists of a backbone that runs from the cabinet on the port side of the companionway to the top of the mast. The backbone requires a terminator at either end. The backbone also requires 12v DC power to operate; this is supplied by the yellow power cable.

The network consists of a backbone, and various "drops" that interface via "T-connectors". The drops on the network currently are:

* Garmin GMI 10 display
* Garmin GPSMap 541 chartplotter
* Yellow 12v DC power cable
* Garmin Intelliducer depth sounder
* Garmin GWS 10 wind instrument
* Vesper XB8000 Class-B AIS Transponder
* Arduino-based data logger

The GMI 10, GPSMap 541, and Vesper XB8000 have their own power connections. The depth sounder and wind instruments draw power from the network.

The network cables have five conductors:

* Red: +12v DC
* Black: Ground
* White: Data+
* Blue: Data-
* bare wire: shield

== Radar ==

* JRC RADAR1000 mounted display
* installed in cubby over Nav Station table

The refrigerator / ice box is located beneath the galley counter and can be accessed via two hinged hatches. There is a shelf in the refrigerator compartment that will accommodate ice blocks.

The refrigerator compressor is made by '''Alder/Barbour'''. The exact model is unknown but appears similar to the '''ColdMachine''' model.

The compressor runs on the 12V house battery and is located in the starboard lazarette outboard of the house battery box. The compressor is powered by a 15A breaker on breaker panel 2 above the galley sink. A thermostat in the ice box controls operation of the compressor.

The compressor has two blade type fuses located at the outboard aft corner:
* 15A Main
* 5A Fans

A diagnostic LED is on the rear panel; the cadence of the LED's flashing indicates the specific problem with the compressor.

X-Dimension Winterization

2018-04-22T18:01:59Z

Scott: Created page with "This is a list of things that must be done to make the boat ready for winter: -- 1-2 weeks before haul-out: * complete all needed paperwork for haul-out marina (e.g. winter s..."

This is a list of things that must be done to make the boat ready for winter:

-- 1-2 weeks before haul-out:
* complete all needed paperwork for haul-out marina (e.g. winter storage application, insurance forms)

-- 2 days before haul-out:
* confirm that marina has you on the schedule, and that all paperwork is complete

-- things to do before you depart for the haul-out:
* remove windex, wind instruments, VHF antenna, and tricolor from top of mast
* replace halyards with messengers
* remove and store cushions at pavilion - hang from ceiling, minimize crushing/kinking/folding.
* sails should be removed from boat and hung from ceiling at pavilion to avoid rodent infestation
* medical kit should be removed to some place that will be above freezing over the winter, to avoid damage to medications.
* make sure you have sufficient antifreeze: 10-11 gals of propylene glycol. There should be no ethylene glycol in the antifreeze - it is a poison.

-- things to do prior to haul-out (could be days ahead or on the way to the marina):
* drain freshwater system. then pour 6 gallons of poly antifreeze (pink stuff) into the freshwater tank. then open hot water faucet at galley until antifreeze comes out. then open hot water faucet at head until antifreeze comes out. then do the same with cold faucets.
* pour pink antifreeze in toilet, pump through to holding tank until you can see about 1/2" of pink in the bottom of the holding tank. should be about 1 gallon for this.
* remove spinnaker blocks from aft mounts and stow them somewhere on board
* remove the paddlewheel speedo sensor

-- after arriving at the haul-out marina:
* winterize the engine. with the boat in the water, run the engine. close the seawater thru-hull. open the cap to the seawater strainer. pour in antifreeze until it starts coming out the exhaust. then shut down the engine. should be about 3-4 gallons of antifreeze for this.

* Ready the mast for pulling:
** REMOVE THE BOLT THRUGH THE MAST STEP AND BASE OF THE MAST
** remove ringdings and loosen shrouds and baby stay
** bend cotter pins so easily removed (but won't fall out)
** Make sure the mast/mast step bolt is removed
** remove the bolts securing the plate at the base of the mast
** remove the mast collar-to-mast tie rods and fittings
** have mast wiring disconnected and tied/taped to avoid fouling
** loosen the pipe clamps holding the mast boot in place
** remove the boom vang
** remove the boom
** when mast is removed ensure that all pins are placed into a plastic cup/bin

--when the boat is on the hard:
* get *all* water out of the bilges and underfloor areas
* open all thru-hulls
* remove steering wheel and stow/tiedown on the bow
* be sure tools are not waterlogged or grease covered

Over the winter anything that can mildew on the boat probably will so you should remove foulies, inflatable pfds, tethers, kitchen towels, etc. These should not go to the pavilion; they tend to disappear over the winter; someone should take these home for safekeeping. The orange pfds usually stay on the boat.

The compass seems to winter better in someone's home than on the boat.

X-Dimension Standard operational procedures

This is a list of concise, preferred operational practices for X-Dimension. For detailed descriptions of systems, please see [[xdim_systems | Systems Descriptions]]. David Collins, the previous owner, wrote the [[Media:X Dimension Manual of Useful Information.pdf | ''Manual Of Useful Information'']].

== Rigging ==

=== Mainsail ===

==== Set ====
* Hoist lazy jack lines. Ensure that they are not snagged on blocks or other fittings on the boom.
* Remove sail ties after hoisting lazy jacks.
* Ease the main sheet slightly, disconnect the main halyard from the boom end and attach to the head of the mainsail
* Optional: assign a crewmember to haul the main halyard at the mast
* Ensure that the mainsheet and boom vang are free
* Head into wind
* With a couple of wraps of the halyard around the port cabintop winch, a crewmember will hoist the main.
* A crewmember at the mast can assist by jumping the halyard.
* Hoisting crew must keep an eye on the leech of the sail to ensure it doesn't snag on the lazy jacks.
* Note: The main sail can be hauled to its full height by a sailor of moderate strength and certainly by two working together. DO NOT use the winch to haul it up - binding is usually due to the halyard being fouled, a sail tie being left in place, or other problem. In these cases, use of the winch will risk breaking the rigging.
* Once the mainsail luff is fully extended, tighten the luff to the desired tension using the winch

==== Close-Hauled Trim ====
* Set the traveler slightly to windward so that with the mainsheet tight, the boom is on the centerline
* Trim the mainsheet so that the top telltale on the leech alternately streams back and curls to leeward
* Note: When close-hauled, the jib tends to backwind the main, creating a slight bubble in the mainsail luff. This is normal.

==== Reaching or Running Trim ====
* If the boom is over the traveler rail, the mainsheet has much more mechanical advantage than the boom vang and should be used as the primary sail shape control
* If the boom is outside of the traveler rail, the boom vang should be used to control the mainsail shape
* When broad reaching or running, the preventer (located in the starboard lazarette) should be attached to a bail on the boom and the toe rail and tightened as needed

==== Reefing ====
* Station two crewmembers (with one winch handle) at the forward end of the boom on the starboard side
* Station one crewmember at the main halyard & mainsheet winches
* Raise lazy jack lines
* Ensure outhaul line is locked in boom clutch, then remove outhaul line from boom winch
* Uncleat reefing line and put two wraps of the reefing line around the boom winch
* Ease the mainsheet to depower the mainsail (head the boat to wind if necessary)
* Ease the main halyard, bring the mainsail luff down, and engage the reef cringle on the reefing horn
* Tighten the main halyard; one crew member at the mast helps with halyard, the other observes and calls to the halyard crew members when the luff tension is correct
* Using the winch on the boom, tighten the reefing line until the reef clew is brought down tight against the boom - cockpit crew calls this to the mast crew
* Secure the reefing line on a cleat on the boom
* Trim the mainsail as desired
* If desired, secure foot of sail with lines through reef points and then lower lazy jacks
* Shake out the reef by reversing the procedure

==== Douse ====
* Remove the lazy jack lines from underneath the reefing horn, tighten and cleat the lazy jack halyard, ensuring that the lazy jacks are in place to catch the mainsail
* Station two crewmembers on each side of mast at the gooseneck and one at the main halyard winch
* Station a third crewmember with sail ties a the ready at the end of the boom on the cabin top (Note: it is helpful to close the companionway hatch so this crewmember can work safely
* When the boat is head to wind, ensure that the mainsheet and boom vang are free
* As the halyard is slowly eased, the crewmembers at the mast alternately flake the mainsail luff to port and starboard
* At the same time, the crewmember at the boom end flakes the mainsail leech, pulling aft at each flake and attaching sail ties
* Note: The crewmember at the halyard should be watching the flaking process to ensure that she is easing the halyard at the appropriate rate.
* Once the mainsail is completely lowered and all ties are in place, the main halyard can be removed from the mainsail head and attached to the boom end
* Ensure that the mainsheet and boom vang are free, then MANUALLY haul the main halyard to level the boom and secure the halyard
* Note: DO NOT use the winch to level the boom with the halyard. Recruit a crewmember if necessary to lift the boom. If the boom is stuck, diagnose the problem. It is usually a fouled mainsheet, main halyard, or boom vang and use of the winch will may break the rigging

=== Genoa ===

==== Set ====
* Free the jib sheets and put two wraps of the working sheet on the primary winch
* Free the black furling line and fake it down so that it will run without fouling
* Station one crewmember on the furling line, another at the working sheet, and a third with a winch handle at the ready
* While the sheet trimmer hauls on the working sheet to unroll the genoa, the crewmember with the furling line should control it so that the line pays out smoothly and under control. Do not allow the sail to unroll violently. In strong wind, it can be helpful to put a bight of furling line around a cleat to help control it.
* Sheet in the genoa to achieve the desired shape
* Secure the furling line
* Note: When reaching or running, the genoa sheets should be lead outboard of the shrouds through the snatch blocks on the rail (make sure that the sheets do not foul on the lifelines). When close-hauled, the genoa sheets should be led inboard of the shrouds through the sheet blocks on the tracks outboard of the cabin top
* Note: Before tacking and jibing, make sure that the lazy sheet is not fouled on one of the winches on the forward cabin top or on the forward hatch

==== Douse ====
* Assign a crewmember to the furling line and another to control the sheets. In strong winds, two crew members may be necessary on the furling line.
* Ease the working sheet to depower the sail
* While one crewmember hauls on the furling line, the other puts slight tension on the genoa sheets to ensure that the sail is tightly furled. To aid in furling, alternate back and forth: slack the sheet while the furling line is hauled, then tighten up the sheet while the furler pauses between heaves.
* Keep furling until there are two wraps of the sheets around the furled sail.
* Note: DO NOT use a winch on the furling line as you will risk breaking the furling mechanism, the turning blocks, and/or the stanchions

=== Asymmetric Spinnaker ===

==== Set ====
* Note: If the course is well off the wind, rig a mainsail preventer
* Pass spinnaker bag up through forward hatch and clip base of bag to lower lifeline on foredeck on side to which spinnaker will be set
* Note: Be sure that tack end of bag (green velcro tab) is facing forward. If necessary, open spinnaker bag and check that tack is forward (tack and clew are labeled on the sail)
* Remove spinnaker sheets from bag and attach snap hooks to sail clew.
* Rig spinnaker sheets outboard of forestay, pulpit, shrouds and lifelines, through large diameter portion of the turning blocks on taffrail to the secondary winches
* Note: Be sure that spinnaker sheets are routed outboard of jib sheets
* Rig tack line from outside the pulpit through the turning block at the base of the forestay to a bow cleat or a winch. For normal operation, the tack line should extend up just at or below the level of the pulpit rail. Attach tack pendant line to spinnaker tack.
* Ease spinnaker halyard and attach to spinnaker head
* Free the snuffing line and flake it down on the deck. Be sure it is not tangled in the sail or running rigging
* Note: Be sure that spinnaker halyard runs outboard of the jib sheets
* Double check spinnaker rigging to be sure that it will run clear
* Assign one or two crewmembers to handle the working sheet (ensure that the lazy sheet is loose, but cleated at its bitter end so it doesn't trail overboard)
* Assign two crewmembers to handle the spinnaker halyard, one to jump the halyard and the other at the winch.
* Assign a crewmember to feed the spinnaker out of its bag and control the snuffing line
* Pre-brief all crew on the operation
* The helmsman should steer for an apparent wind angle (AWA) of about 110 degrees (light air) to 130 degrees (heavy air)
* Note: These AWA figures may not be as critical when using the snuffer
* Hoist the snuffed sail until the head is tight at the masthead. Avoid excessive tension with the winch as the halyard can foul in the sheeve.
* The crewmember on the snuffing line should haul the side of the line not attached to the snuffing "funnel" so that the snuffer retracts along the sail toward the masthead.
* The crewmember on the working sheet should trim smoothly as the sail unsnuffs so that the sail fills evenly. Do not oversheet as this can cause excess tension on the leech as it pays out of the snuffer
* When the snuffer is fully retracted and the sail fills, ease the sheet to obtain a slight hook in the luff
* Secure the snuffing line at the base of the mast
* As the luff approaches the headstay, the tack pendant can be eased to achieve the proper sail shape
* The helmsman should keep the boat at a constant AWA throughout the set
* Note: Clear communication is very important. There should be one and only one person in charge during spinnaker operations. It is best if this person is not one of the crewmembers setting the sail or the helmsman

==== Flying ====

* The sail trimmer should be positioned at or near the windward shrouds where she can see the luff
* The sheet should be led from the secondary winch, across the cockpit, where it can be held by the sail trimmer
* A crewmember should be at the winch to grind when the trimmer calls for it - the trimmer will tail the sheet as necessary
* The trimmer should trim and ease as necessary to keep a slight hook in the luff of the sail
* The helmsman should keep a steady course and alter it only with clear communication with the trimmer
* When on a close reach, trimming may be insufficient to recover a collapsing sail. In this case, the trimmer should call for the helmsman to fall off slightly

==== Douse ====

* Assign crew to the tack pendant, and the snuffing line
* Bring the tack down until it is just above the bow pulpit
* Free the snuffing line from the base of the mast
* Ease the sheet to depower the sail and haul down the snuffing line on the side where it attaches to the "funnel"
* As the snuffer approaches the foot of the sail, ease the tack pendant to allow the foot and the snuffer "funnel" to be brought inboard of the lifeline and placed in The spinnaker bag.
* If the winds and seas are light, attach the tack and clew to the spinnaker bag and then flake the snuffed sail into the bag as the halyard is eased
* If the winds and seas are heavy, bring the snuffer down on deck under control, then place in the bag
* Attach the head to the spinnaker bag and secure the halyard at the base of the mast
* flake the snuffing line into the spinnaker bag
* Coil the spinnaker sheets and place in the spinnaker bag
* Close the bag and pass it down the forward hatch

==== Tacking and Jibing ====

* There are two options for jibing the spinnaker as shown in the videos below
* Jibing the spinnaker on the outside: http://www.youtube.com/watch?v=WbLoLfL0Lfk
* Jibing the spinnaker on the inside: http://www.youtube.com/watch?v=YEhfuK_tAr8
* On X Dimension, jibing the spinnaker on the inside works well in lighter air (less than about 6 knots). In heavier air, consider either jibing the spinnaker on the outside or snuffing the spinnaker and bringing it around the forestay snuffed before unsnuffing it on the new jibe.

== Engine ==
=== Starting ===

* Engine Battery Switch above galley sink must be ON
* Transmission must be in neutral (port lever horizontal)
* Throttle (starboard lever) up slightly (half an inch)
* Assure engine stop control (T-handle) is in run position (down)
* Turn on (up) the grey Ignition Switch on the binnacle; buzzer will sound
* Press black starter button (middle button above ignition switch)
* Throttle down to idle after engine starts
* Check oil pressure gauge to ensure pressure rises after start
* Check exhaust on the transom to ensure cooling water is being expelled
* If water is not expelled, turn off engine immediately to prevent overheating

=== Shifting ===

* Throttle must be at idle before shifting (starboard lever down)
* Transmission settings (port side lever): ahead propulsion (lever up), astern propulsion (lever down), neutral (lever horizontal)
NOTE: FAILURE TO SET THROTTLE AT IDLE BEFORE SHIFTING WILL DAMAGE PROPELLER FEATHERING MECHANISM

=== Stopping Engine While Under Sail (to feather propeller)===

* Transmission must be in ahead propulsion (port lever down)
* Boat speed must be at least 5 knots through the water so that prop feathers when engine stops (use throttle as necessary to supplement sails)
* Keeping transmission in ahead propulsion, pull engine stop control (T-handle) up; engine will stop and buzzer will sound
* Turn off (push down) grey Ignition Switch on binnacle; buzzer will silence
* Move transmission lever to neutral (port lever horizontal) to prepare for next start
* Visually check prop shaft (can be viewed easily from starboard lazarette opening); if rotating quickly, then prop has not feathered and process must be repeated at a higher boat speed. If rotating slowly, place transmission in astern propulsion to stop rotation.
NOTE: If engine is stopped while in astern propulsion, the propeller will not feather.

=== Stopping Engine ===

* Transmission in neutral (port lever horizontal)
* Throttle at idle (starboard lever down)
* If engine has been running hard and is hot, allow to idle for a few minutes to cool before stopping engine
* Pull engine stop control (T-handle) to up position; engine will stop and buzzer will sound
* Push down the grey Ignition Switch (starboard on binnacle, under start button)
* Turn off the Engine Battery Switch (above galley sink) before leaving the boat

== Head ==

== Electrical ==

=== House Battery Switch ===

* The House Battery switch should be turned to HOUSE when you enter the boat. This supplies power to most of the electrical systems and allows the battery to be charged if you start the engine.
* The House Battery switch should be turned OFF when you leave the boat.
* The House Battery switch should never be turned to "Both" or to "2" except in the event of an emergency.

=== Charging Batteries ===

* Switch the House Battery Switch to HOUSE
* Turn on the Engine Battery Switch
* Start the Engine (see above)
* Check the HEHR Regulator on the bulkhead inside the starboard lazarette
* The orange, yellow, and green LEDs on the regulator should be on
* If the red low-voltage LED is on, increase the engine throttle until the red LED turns off.

=== Navigation Instruments ===

Quick start for GPSMap541:

* press HOME
* select "Charts" with the arrow keys, then press SELECT
* Select "Navigation Chart" with the arrow keys, then press SELECT

Please read the owners manuals for the GPSMap541 and the GM10 (located in the documentation folder inside the navigation table) for more detailed operation of these units.

=== VHF Radio ===

The fixed mount VHF radio receives latitude and longitude data from the Garmin GPSMap541. Always make sure the "Navigation Instruments" are turned on at the breaker panel whenever the VHF Radio is turned on. A "satellite" icon will appear on the front panel of the radio to indicate that it is correctly receiving position data from the GPS.

In a life-threatening emergency, an automatic distress call can be initiated by lifting the hinged red plastic cover labeled "Distress" and holding down the button for five seconds. This should send out a digital distress call and then switch the radio to channel 16. You must also make a voice Mayday call on channel 16.

For more details about operation of the VHF radio, please see the owners manual (located in the documentation folder inside the nav station table).

=== Navigation Lights ===

Navigation lights must be turned on between sunset and sunrise.

* '''Under sail power in a harbor'''

Turn on "Running Lights" only. This turns on the red and green sidelights in the bow and the white stern light. Note that these are easier to see by nearby boats than the Tri-color.

* '''Under sail power in open seas'''

Turn on "Tri-Color" only. This is easier to see from a distance than the running lights and uses less power.

* '''Under motor power'''

Turn on "Running Lights" and "Steaming Light". Use of the tri-color is not allowed while motoring.

* '''At anchor'''

Turn on "Anchor Light" only. Note that the anchor light is not necessary while in a "Special Anchorage".

=== Emergency Battery Operations ===

The House Battery Switch should normally be turned to HOUSE for operation of the 12v systems and for proper charging of both Engine and House batteries, or OFF before leaving the boat. The other switch positions should be used only in emergency situations. For example:

* If the Engine Battery is depleted and the engine needs to be started in an emergency, the Engine Battery bank and the House Battery can be tied together in parallel by switching the House Battery Switch to "both". If there is enough power left in the House Battery bank, it may be able to start the engine. Note that this will immediately start draining the House batteries as the dead Engine Battery pulls current from them. Also note that the charging system may not work properly in this configuration.

* If the House Battery bank is depleted and electrical systems need to be used (such as the VHF radio), the Engine Battery can be used to power the 12v systems by turning the House Battery Switch to "2". The "Engine" and "Fuel Pump" breakers can be turned off in this situation to save power and quiet the alarm buzzer. Note that this will not power the electric bilge pumps. To power the bilge pumps in this situation, the House Battery Switch should be turned to "Both".

== Freshwater ==

== Galley ==

===Lighting Galley Stove===
* Open valve at top of propane tank (located in Port Lazarette)
* Switch on electrical panel above galley sink to 'on'
* Switch on bulkhead above galley stove to 'on' (Note: pilot light on switch inoperative)
* Light butane lighter or strike match
* Press in control knob for desired burner on stove and turn to light position
* Light burner
* Hold in knob for about 20-30 seconds then release

NOTE: Turn off both electrical switches and close valve at top of propane tank after each use

If a task needs additional explanation, please make a page for that task and post updates. When a task is completed, move it to the 'Completed Tasks' section, and include the date it was completed.

Please use the discussion page to discuss the prioritization and content of any of these tasks.

== Pre-2017 splash work ==

* Clean the bottom. Maybe paint the bottom. The bottom will change color in August, so there’s no need to put two coats of black on, or maybe even get new black bottom paint.

* Work on the fuel tank. This might be better done in Aug, when it will be warm. I’d recommend getting 6” SS access ports; 4” might be too small. I like the Seabuilt ports.

* Engine maintenance - put oil in the engine, change the filters, etc.

* Change the faucet in the head. It leaks.

* Maintain the manual bilge pumps. Neither works particularly well at this point.

* Electric bilge pumps - does anyone know the status of these? I seem to recall that one or none of these worked well.

* New jib sheets - did these ever get ordered?

* Sails - did the spinnaker, #3, and #1 ever make it to North? It might be too late for these now.

* Fill the propane tank

* Re-install the bolts for the toe rail, using butyl to seal them.

* Replace the foam seals on the forward hatch. The forward hatch generally leaks, so that could be a project for someone.

* Pieces of the wood framing around the companionway hatch are rotted; these will need to be replaced at some point. Not necessarily a pre-launch thing.

* Table nut fasteners - this needs to be done (finally!).

* Inspect and lube steering gear

== 2016 Off-season work ==
Based on the skipper's meeting of Tue 27 Sept. Please put your name next to things you'd like to lead/contribute to.

* Mast partners: need to develop a template so we can fashion partners out of hard rubber wedges.

* Topsides: the plan is to pull the boat in Aug 2017 and redo the topsides and replace the engine with a Yanmar.

* Toerails: do this fall. Remove one side and replace that side, using the existing toerail on the other side to crank the new toerail into shape. Will need to fill in the old boltholes (w/ Pro-Set), and then drill new holes. We will pull the boat once we have all the needed goodies - toerails, bolts, drillbits, etc. Challenge: finding new toerail extrusions.

* Engine: re-engine boat with new Yanmar during the time the boat topsides are being repainted.

* Rear quarter plates - do at the same time as toerails. Re-fab out of aluminum or S/S if we are sure the quarter plates will not touch the aluminum toerails.

* Deck core rot: could be a minor matter. Scott to find the right moisture meter to survey deck and hull.

* Fuel tank: old one will be removed and replaced with a new solid tank in same spot as old tank. Will outsource work/ have work overseen by someone who has experience doing this. Adam to take lead.

* Jib and Main sheets: replace now before end of 2016 season. New jib sheets should be a smaller diameter than the current sheets. Get length & diameter to Fran.

* Bow roller/ electric windlass/ hawsepipe: Look into getting this on the boat. Fran thinks this is important for safety. Violeta to research.

* Take asym to North for repair estimate (Adam)

* Bilge pumps: fix diaphragm pump, diagnose submersible pump, fix cockpit manual pump.

Smaller things:
* Red dinghy motor - take to Crystal Cove. Engine does not idle well.
* Get gray dinghy motor from C.C.
* Solar panel needs to be more permanently installed. Eric to lead.
* Replace faucet in head
* Table nut fasteners - this needs to be done (finally!).
* wood at forward end of companionway - needs repair. wood at forward end of companionway is also rotten.
* New brakes for wheel lock - Ted to take lead.
* Inspect steering gear
* Address crack in spreader bracket
* Spot paint mast after prep.
* hooks on shrouds to hold Spin hlyd
Things to not do:
* paint the bottom - this will happen in Aug 2017. Bottom to be painted with Shark White or MIT Gray so we can see when it is dirty.

== Pre-splash 2016 Tasklist ==
* Fix engine oil leaks - Lloyd. Someone sent by Lloyd worked on the leak before splash. What's the result?
* Replace nuts on rear quarter fittings - Scott
* Inspect steering gear, grease rudderpost - Ted
* Remove corrosion on mast and boom; repaint - Eric (postponed for next year?)
* Touch up topsides paint - Greg says he will take care of this if we have time prior to splash.
* Cetol woodwork - Violeta - postponed for after splash (too cold and/or windy before that)

[[(by person)]]

WM shopping list (everyone add stuff here):
* 33g CO2 cylinder for Spinlock Deckvest (tall and thin preferred)
* 50/50 antifreeze - 1 gal.

Things that are important that may need to wait:

* Remove, refurbish and reinstall rear quarter aluminum plates (used for spinnaker turning blocks) - Scott. We may not be able to have these fabbed within our timeline.
* Repair soft spots on deck: over head, just aft of fwd stbd cleat, other? Not this year
* Remount boom winch - Scott. I looked at this a few days ago, and it looks pretty good.
* Toerails? No.
* re-tab bulkheads to hull? No.
* obtain recent iPad for iNavX -Scott. I’m still working on this...
* sell old AIS/splitter/NMEA2000 -> USB devices. Where are these? I looked for them on the boat and didn’t find them. Selling these would pay for a usable iPad.
* replace jackline mounting points with cleats. Still want to do this, but can be done with the boat in the water
* Remove, refurbish and reinstall fuel tank - Adam. This is being put off to next fall.

Offshore2017

2018-01-07T15:24:07Z

Scott:

This is the outline for the offshore sailing course, January 2017.

=Title:=
Offshore Sailing Shore School

IAP listing: http://student.mit.edu/searchiap/iap-9289af8d5862a09a01588396c2fc01cd.html

Location: 66-160 (http://whereis.mit.edu/?go=66)

=Bluewater Shore School=
You know that MIT has a fabulous river sailing program, but did you also know that MIT also has an offshore sailing program, where you can sail MIT's 43-foot boat, X Dimension, in Boston Harbor, to P-town, along the Maine coast, and even to Halifax, Nova Scotia?

The purpose of this IAP course is to show you that sailing a 43-foot boat differs from dinghy sailing only in degree: the boat and sails are bigger, you can stay out longer (days!), and you don’t have to come back to the dock at night. We are offering 8 sessions that will cover the fundamental and practical aspects of large boat sailing, with the goal of making everyone feel equipped with the knowledge to feel comfortable sailing along the coast. The classes will cover keelboats, weather, navigation (including celestial navigation), safety at sea, racing, and chartering a boat in the Caribbean.

No prior knowledge of keelboats or sailing is required (though the latter is very helpful); just an interest in learning about sailing in the salt water.

Times:
Tuesdays & Thursdays 6:30-8:30

=Sessions=
==Tue Jan 10: Introduction to Keelboats - Eric Brown==
Whether you're out for a day sail or crossing the ocean, you'll need to understand the various onboard systems. This session provides basic knowledge of the typical coastal cruising sailboat -- structure, rigging, electrical, engine, navigation, etc. Attendees will learn the nautical terms for things (the galley, not the kitchen), feel comfortable finding their way around a boat, and get a sense for life aboard at sea.

* Slides from this session: [[File:MIT_IAP_2017_-_Offshore_Sailing_-_Introduction.pptx]]

==Thu Jan 12: Chartering a boat - Tim Hall==
If you have some experience sailing, there's a good chance you can charter a boat in the Caribbean and elsewhere. This session discusses the practical aspects of arranging for and sailing a charter in the Caribbean. Topics we will talk about include:
* Choosing crew
* Checking out the boat (what to look for)
* Provisioning the boat
* Cooking on board and planning meals
* What to bring and how to dress
* Clearing customs and sailing among the islands of different countries
* Seasickness

Chartering is much easier than you imagine - and the water really is bluer in the Caribbean!

==Tue Jan 17: Racing - Adam Traina==
Racing is a very fun and very effective way to learn how to sail well; you are on a boat with expert sailors who are helping you to correctly trim, drive, navigate and in general sail the boat. In this session we will introduce sailboat racing and cover a broad range of topics that will enable you to have fun while racing keelboats. Topics we will cover include:

* what does it even mean to race boat that are really different?
* different types of races: courses, regular vs. chase races.
* the basic racing rules of sailing
* starts (very different from auto race starts!)
* sail trim
* racing and sailing tactics

==Thu Jan 19: Navigation #1 - Ted Young==
Where are you? How will you get to your destination safely? In this course we will cover the
basics of coastal navigation, including how to read nautical charts, identification of navigation
aids, and proper use of a magnetic compass.

* Slides from this session: [[File:Navigation_IAP_2017_1.pdf]]

==Tue Jan 24: Safety at Sea - Scott Dynes==
This session covers what you need to know to be safe sailing bigger boats offshore. Topics covered will include:
* Personal responsibility and managing risk
* What to wear
* On the boat and boat handling
* Communication
* Things to keep you safe (e.g. harnesses and tethers)
* Things to keep others safe (e.g. man overboard procedures)
* Sailing in different kinds of weather

To the extent possible we will demonstrate equipment and procedures.

==Thu Jan 26: Navigation #2 - Ted Young==
In part two of this introduction to coastal navigation, we will further discuss skills for safe navigation, including understanding of tides and currents, piloting and dead reckoning, the navigation rules, as well as techniques for using electronic devices such as depth sounders, GPS, and RADAR.

* Slides from this session: [[File:Navigation_IAP_2017_2.pdf]]

==Tue Jan 31: Weather - Eric Brown==
You’ve probably heard ‘Red sky at night, sailor’s delight; red sky in morning, sailors take warning’, but did you ever wonder why that is so? In this session we will cover many aspects of weather as it related to sailing, including:
* Weather basics: high and low pressure, warm and cold fronts, and what it all means for the sailor.
* Observational weather - what can you tell about future weather based on what you are seeing now?
* NOAA weather forecasts - there’s a lot of information, and we will make sense of it.
* How to get weather information at sea, when there is no 6 o’clock news.

* Slides from this session: [[File:MIT_IAP_2017_-_Offshore_Sailing_-_Weather.pptx]]

==Thu Feb 2: Celestial Navigation - Adam Traina==
Before there was GPS, there were the stars. Ocean voyagers have used the stars to generally navigate for millennia, and precisely navigate since the invention of the marine chronometer. In this session we will go through the theory and practice of celestial navigation; we hope to have enough sextants to allow for hands-on activities. While you will not walk away from this class knowing how to navigate by the stars, you will know why and how it works, and what to do next if you want to learn celestial navigation in detail.

* Total length of mast: 63' 11.5"
* Height of mast above deck: 57' 0.5"
* Height of lower spreader above deck: 22' 0.5"
* Height of upper spreader above deck: 41' 2.75"
* Height of foredeck light above deck: 25'
* Distance from base of mast to deck: 6' 11"
* Distance from base of mast to foredeck light: 31' 11"

== Standing Rigging ==

=== Shrouds and Spreaders ===

Standing rigging on the mast was inspected in detail March 2016. All rod rig fittings were removed, mushroom ends cleaned and regreased and reassembled except for the port lower spreader cup - there's one sticky set screw that cannot be loosened. Red threadlocker was used where appropriate. As a result of the inspection the upper starboard shroud (from the lower spreader to the masthead) was removed and taken to the riggers, where the lower end was cut off, the ferrule replaced, and a new head formed. The rigger said this was a non-standard size; he thinks it is not a Navtec rod but another make. He says a size 15 die (not a usual Navtec size) is the best match.

During the inspection everything seemed fine except the ferrules for the upper ends of the upper diagonals (lower spreaders to upper spreaders) could not be freed from the rod; the heads looked fine. Again, the port lower spreader cup could not be disassembled.

The rigger that we used: Kevin at NorthEast Rigging, 978-287-0060, http://nerigging.com/.

=== Headstay and Backstay ===

A Harken Mark III (Unit Size 2) headstay roller furling system is installed on the headstay. The drum should roll clockwise when rolling in the headsail. Owner's manual can be found at [http://www.harken.com/uploadedfiles/Product_Support/PDF/mk3-2-4865.pdf]

The backstay has a Sailtec Integral Backstay Adjuster (Model 10SI), [http://www.sailtec.com/public/sailtec_bochure_2007.pdf brochure on web] (no operating instructions). When sailing upwind, the backstay should be adjusted so that the piston is approximately 2 inches from the white gauge on the shaft (2" minimum). Cross check the headstay sag. In moderate winds, the headstay should have very little sag.

==Running Rigging==

=== Halyards ===

* Main halyard: 125' long x 1/2 " (core unknown). As of Feb 2016 we have two in good condition.
* Jib halyard: 125' long x 7/16" dia. with hi-tech core with no creep. As of March 2016 we have two in good condition, one new (solid green color) as of March 2016.
* Spinnaker halyard: One 125' long x 7/16" dia. with hi-tech core (creep OK), one 125' long x 7/16" dia. of Sta-Set new as of March 2016.
* Spinnaker pole topping lift: 95' long x 3/8" dia of Sta-Set. No need for a high-tech core here. New as of March 2016.

The covering of many of the jib/spin halyards is worn about 20' from the snap shackle, which would be about the level of the upper spreaders when the halyards are attached to a sail and tensioned. Inspection in March 2016 indicated that the screws holding the birdlines above the upper spreaders are the likely cause - these were too long and protruded inside the mast. They were set to a length that was flush with the inside of the mast and locked with nuts on the outside of the mast prior to launch in April 2016.

=== Sheets ===

* 2016 season main sheet: Main sheet 52' x 9/16" measured
* 2016 season jib sheet: 58' x 3/4 " measured (remeasured: 58 1/2 feet long)
The 2016 season jib sheet diameter was clearly too big - it was hard to fit through blocks, and was a little big for the winches. It was easy on the hands, though.

=== Traveler ===

The traveler is built of Harken "big boat" and HL (high load). The purchase is 4:1.

* track: 5 foot long Harken 32mm
* end controls: Harken 5170 with cam cleat
* car: Harken T3242B.HL

=== Boom Vang ===

* The boom vang was repaired in 2013. The spring and the vang tube were replaced.
* If necessary to adjust the vang to level the boom, first attach a topping lift to the boom (the main halyard will serve this purpose well). When the weight of the boom is held by the topping lift, remove the two 10-32 allen head cap screws that are located on either side of the vang tube near where the red indicator tab is in the vang tube slot. These allen head cap screws fit into a series of threaded holes in the inner aluminum thick walled tube that carries the red indicator tab. This tube serves as the stop for the main vang spring. Raise or lower the boom until the proper threaded holes line up with the clearance holes in the outer tube and re-install the cap screws.

= Sails =

== Sails Kept on the Boat==

General: The [[http://sailing.mit.edu/wikiupload/3/31/X_Dimension_Manual_of_Useful_Information.pdf Owners "Helpful Hints"]] has various advice in the pages 4-5 "Sail Control" section.

===Mainsail===

When not sailing, the mainsail is normally kept flaked on the boom with a sail cover.

While hoisting, reefing, or flaking the mainsail, the "lazy jacks" (E-Z-JAX system) can help contain it. See the [[Media:Lazy Jack Installation Instructions.pdf |E-Z-Jax system manual]] (untitled pdf) for operation instructions (page 4).

===Headsails===

The #3 Genoa (approximately 135%) is an older sail. Can be sheeted inside or outside the shrouds.

The #1 Genoa was purchased for the 2014 season.

There is a UV shield on the #1 and #3 genoas. Port side. Make sure it is exposed when the sail is left furled on the drum. The drum should roll clockwise when rolling in the sail.

The #4 jib/ heavy-weather jib was purchased for the 2016 season. There is no UV shield on this sail; please do not store it on the headstay.

===Spinnaker===

New for the 2016 sailing season is an asymmetric 'runner'.

== Sail Inventory (as of May 2016)==

=== Mainsails ===

The mainsail was purchased new prior to the 2014 season, and is on the boat during the sailing season and in the end bay of the pavilion off-season.

Storm Trysail

=== Jibs and Genoas ===

Genoa #1 was purchased new prior to the 2014 season, and is on the boat during the sailing season and in the end bay of the pavilion off-season. There is a UV shield on the Genoa, port side. Make sure it is exposed when the sail is left furled on the drum. The drum should roll clockwise when rolling in the sail.

Genoa #3 (tied with sail ties, but not in a sail bag)

There is a UV shield on the #1 and #3 genoas. Port side. Make sure it is exposed when the sail is left furled on the drum. The drum should roll clockwise when rolling in the sail.

A #4 jib/ Heavy-weather jib (satisfies ISAF HW jib definition): purchased new in Spring 2016. There is no UV shield on this sail; do not roller furl this jib - take it off the headstay.

Storm jib, new in 2013.

=== Asymmetric Spinnaker ===

We have a ~new asymmetric spinnaker as of Spring 2016. Shredded in June 2016. To be diagnosed, possibly repaired off season.

=== Symmetric Spinnakers ===

As of May 2015 we do not have the capability to fly symmetric spinnakers on the boat.

0.5 oz Tri Radial Symmetric Spinnaker (in North Sails blue bag dated 1979)

0.75 oz Symmetric Spinnaker (in North Sails blue bag)

1.5 oz Tri Radial Symmetric Spinnaker (in blue sail bag)

Three symmetric spinnakers (one of each weight) were relocated to S. Dynes' garage for hanging storage Oct 2013.

=== Sails We Used To Own ===

The original working main that came with the boat blew out at the end of the 2013 season. North Sails deemed it unrepairable.

A spare main, originally for the previous mast and unable to be mounted on the current mast without changing slugs. Discarded as part of a pavilion cleanup fall 2013.

Original Genoa #2. A panel split during the 2013 season; North Sails deemed it unrepairable.

Original Genoa #1. Various tears/holes during the 2013 season; North Sails deemed it unrepairable ("nothing to sew to'). Discarded as part of a pavilion cleanup fall 2013.

Working Asymmetric Spinnaker : blew out a panel at the end of the 2014 season, North Sails deemed it unrepairable.

== Companionway Hatch Removal ==

* Remove Forward Hatch Stop by removing three wood screws on the ceiling of the coach roof just forward of the companionway opening. Slide the stop out between the hatch and the coaming.

* Remove the wood screws holding the hatch rails to the hatch. All screws except the furthest forward screws will be accessible. Once these are removed, the rails may be rotated outboard and the hatch slid aft to access the last two screws. Remove the hatch.

== Steering ==

=== Helm ===

* The steering wheel is trapped by the fiberglass cover in the center of the cockpit. Remove this cover to remove the steering wheel.
* The emergency tiller is a long steel bar inserted into a square hole beneath an inspection portal in the fiberglass cover aft of the helm. The tiller is kept in the starboard lazarette.

=== Rudder ===

* When hauled in Nov 2011, the rudder was saturated with water. 4 holes were drilled to drain it over the winter, then plugged in May 2012.
* The rudder was pulled Dec 2011 and the shaft repacked. Prior to this time there was a steady trickle of water entering the boat from the rudder post.

== Thru-Hulls ==

As delivered to MIT in August 2011, X-Dimension had 11 thru-hulls. 
After Winter 2011/2012 refurb, the thru-hulls are:

* port v-berth 1.5" - blackwater out
* port forward of keel 1" - greywater out
* port mid-keel 0.75" - toilet in
* stbd mid-keel 0.75" - galley seawater
* port mid-keel 2" - speed impeller
* stbd mid-keel 2" - depth transceiver (epoxied in place)
* stbd aft of keel 1.5" - galley greywater out
* stbd mid cockpit 1" - engine in
* stbd cockpit 1.5" - scuppers
* port cockpit 1.5" - scuppers
* port cockpit 1/2" at waterline - propane drain

There are two vestigial thru-hulls, one for an impeller and the other for a depth transducer. These are located just aft of the main cabin forward bulkhead, beneath the cabinets.

In June 2013 another thru-hull was added:
* port v-berth 2" - combined speed paddlewheel/depth-sounder/water temperature

== Bilge Pumps ==

There are two electric bilge pumps and two manual bilge pumps. An electric submersible pump is in the central portion of the bilge well. A diaphragm electric pump is in the cabinet beneath the nav station. Float switches for the two electric pumps are located in the bilge well. The diaphragm pump's float switch is in the deepest part of the bilge; it should energize first and keep the bilge dry. The submersible pump's float switch is forward and higher; it should energize if there is an inch or more water in the bilge.

The two electric bilge pumps are connected to the House batteries via the always-on "Bilge Pumps" breaker on [[X-Dimension_systems#Circuit_Breaker_Panel_1|breaker panel #1]]. Individual auto-manual-off controls for the electric pumps are located port of the nav station. Note that the "Bilge Pumps" breaker bypasses the House Battery Switch and the pumps will still operate if the House Battery Switch is off. (See [http://sailing.mit.edu/wikiupload/3/3c/X-dimension_bilge_circuits.pdf X Dimension Bilge Pump Wiring])

The cockpit manual pump is located on the port bulkhead of the cockpit just forward of the helm. The high-volume manual pump is located under the floorboards of the hanging locker behind the nav station, and can be operated without removing the floorboards. The handles for the two manual pumps are stored in the hanging locker behind the nav station. The smaller handle fits the pump in the cockpit, and the longer handle the pump behind the nav station.

All bilge hoses exit the boat starboard of center at the transom.

=== Submersible Electric Bilge Pump ===

Maintained March 2017.

'''Note:''' the high volume manual pump is operated with the long handle from inside the locker behind the nav station. The pump itself is underneath the floorboards in that locker; the handle is inserted into the pump through a cut-out in the floorboards on the starboard side of the locker (to your left when looking into the locker). The cutout may be covered by stored items, such as PFDs, which must be removed to access the pump.

=== Strum Boxes ===

* Strum boxes are 1 1/2" West Marine part # 100729, Whale mfg. part # SB5865

== Head ==

The head is a hand-operated marine toilet unit connected to a 25 gallon expanding holding tank. The output from the toilet goes into the holding tank. From the holding tank there are two hoses, one to a pump-out fitting on the deck, the other to a thru-hull under the forward cabin sink.

The forward facing panel beneath the sink in the forward cabin can be removed for access to the thru-hull valve.

The seawater in thru-hull is located port of center under the main cabin floorboards, just aft of the mast. A small mesh strainer is located inline soon after the thru-hull valve.

The toilet is Jabsco model 29090-2000 (compact bowl & seat).

= Electrical =

== 12-volt ==

=== Batteries ===

There are two independent sets of batteries on the boat. The "Engine" battery (or "Starter Battery") is used for starting the engine. The "House" batteries supply power to most of the rest of the electrical equipment onboard.

The House batteries are charged by the alternator. The Engine battery is charged via the Balmar Duo Charge, mounted on the bulkhead above and just forward of the House batteries. A solar panel was installed in 2015 to trickle-charge the house batteries.

==== Engine Battery ====

The Engine Battery is a marine dual-purpose AGM battery. The battery is located in the port lazarette, next to the water heater, and under the propane tank.

The Engine battery is isolated by the Engine Battery Switch, located alongside the circuit breakers above the galley sink. The Engine Battery Switch is an on/off switch, located by the circuit breaker panels above the galley sink.

When the Engine Battery Switch is on, power is connected to the starter motor and to the "Ignition Switch" on the binnacle in the cockpit through the always-on 50 amp "Engine" breaker above the galley sink. The Ignition Switch on the binnacle powers the following circuits:

* Starter button on binnacle (connected to starter solenoid)
* Balmar charging regulator
* Engine instruments in cockpit instrument panel
* Engine temperature sensors, oil pressure sensor and alarm buzzer
* Electric inline Fuel Pump located under port settee, just aft of the fuel tank

The Engine Battery Switch should be switched to OFF when leaving the boat.

==== House Batteries ====

The House battery bank consists of two Lifeline GPL-31T deep-cycle marine AGM batteries, tied together in parallel. This battery bank is located in the starboard lazarette, just aft of a bulkhead that separates the lazarette from the main cabin. The House battery compartment is usually covered by a white wooden tray that contains winch handles.

The House battery bank is isolated by the House Battery Switch, located alongside the circuit breakers above the galley sink.
The House Battery Switch is a four-way switch located by the circuit breaker panels above the galley sink. During normal operation of the boat, the House Battery Switch should be switched to the "House" position. This allows the house battery bank to be charged by the engine, and to power the various 12-volt devices through the breakers above the galley sink.

The House Battery Switch should be switched to "OFF" when leaving the boat.

The two additional positions on the House Battery Switch will enable parallel use of the House battery bank and the Engine battery, and should only be used in case of emergency. (See [http://sailing.mit.edu/wiki/index.php/Standard_operational_procedures#Emergency_Battery_Operations Emergency Battery Operations]) Note that the Engine Battery Switch must be ON in order to use the House Battery Switch as an emergency parallel switch.

=== Solar Charging ===

A 55-watt '''Ganz GSP-55 solar panel''' is installed on the v-berth hatch. The cable snakes through the dorade box into the head, then along the port wiring conduit. It connects to a '''Morningstar SunSaver MPPT solar controller''' which charges the House battery bank directly (not through the House Battery Switch).

=== Circuit Breaker Panels ===

As of September 2016, there are four circuit breaker panels above the galley sink, and one panel in the cockpit.

*'''Note''': Any circuits that are not currently connected will be labeled "N/C" with blue tape at the circuit breaker.

==== Circuit Breaker Panel 4 ====

As of September 2016, this Breaker panel is not being used. Some of the breakers may be used for other circuits in the future. Some of the space on the panel may also be used for ammeters in the future.

==== Nav Lights Fuse Panel ====

The dark grey plastic panel in the cockpit, starboard of the wheel, is a Blue Sea Systems "[http://bluesea.com/category/16/products/4306 WeatherDeck Waterproof Fuse Panel]". The navigation lights on the boat are controlled through this six-position panel.

Power to this panel is supplied by the "Navigation Lights Master" circuit breaker on the control panels above the galley sink. Each of the six circuits is protected by an internal blade-type fuse. When power is supplied to the panel, and the corresponding fuses are not blown, then the circuit indicator labels will glow red. When each circuit is switched on, then the label will glow green. If the label does not glow, then the fuse is probably blown. Please see the instruction manual for fuse replacement.

== Mast and Boom ==

* Total length of mast: 63' 11.5"
* Height of mast above deck: 57' 0.5"
* Height of lower spreader above deck: 22' 0.5"
* Height of upper spreader above deck: 41' 2.75"
* Height of foredeck light above deck: 25'
* Distance from base of mast to deck: 6' 11"
* Distance from base of mast to foredeck light: 31' 11"

== Standing Rigging ==

=== Shrouds and Spreaders ===

Standing rigging on the mast was inspected in detail March 2016. All rod rig fittings were removed, mushroom ends cleaned and regreased and reassembled except for the port lower spreader cup - there's one sticky set screw that cannot be loosened. Red threadlocker was used where appropriate. As a result of the inspection the upper starboard shroud (from the lower spreader to the masthead) was removed and taken to the riggers, where the lower end was cut off, the ferrule replaced, and a new head formed. The rigger said this was a non-standard size; he thinks it is not a Navtec rod but another make. He says a size 15 die (not a usual Navtec size) is the best match.

During the inspection everything seemed fine except the ferrules for the upper ends of the upper diagonals (lower spreaders to upper spreaders) could not be freed from the rod; the heads looked fine. Again, the port lower spreader cup could not be disassembled.

The rigger that we used: Kevin at NorthEast Rigging, 978-287-0060, http://nerigging.com/.

=== Headstay and Backstay ===

A Harken Mark III (Unit Size 2) headstay roller furling system is installed on the headstay. The drum should roll clockwise when rolling in the headsail. Owner's manual can be found at [http://www.harken.com/uploadedfiles/Product_Support/PDF/mk3-2-4865.pdf]

The backstay has a Sailtec Integral Backstay Adjuster (Model 10SI), [http://www.sailtec.com/public/sailtec_bochure_2007.pdf brochure on web] (no operating instructions). When sailing upwind, the backstay should be adjusted so that the piston is approximately 2 inches from the white gauge on the shaft (2" minimum). Cross check the headstay sag. In moderate winds, the headstay should have very little sag.

==Running Rigging==

=== Halyards ===

* Main halyard: 125' long x 1/2 " (core unknown). As of Feb 2016 we have two in good condition.
* Jib halyard: 125' long x 7/16" dia. with hi-tech core with no creep. As of March 2016 we have two in good condition, one new (solid green color) as of March 2016.
* Spinnaker halyard: One 125' long x 7/16" dia. with hi-tech core (creep OK), one 125' long x 7/16" dia. of Sta-Set new as of March 2016.
* Spinnaker pole topping lift: 95' long x 3/8" dia of Sta-Set. No need for a high-tech core here. New as of March 2016.

The covering of many of the jib/spin halyards is worn about 20' from the snap shackle, which would be about the level of the upper spreaders when the halyards are attached to a sail and tensioned. Inspection in March 2016 indicated that the screws holding the birdlines above the upper spreaders are the likely cause - these were too long and protruded inside the mast. They were set to a length that was flush with the inside of the mast and locked with nuts on the outside of the mast prior to launch in April 2016.

=== Sheets ===

* 2016 season main sheet: Main sheet 52' x 9/16" measured
* 2016 season jib sheet: 58' x 3/4 " measured (remeasured: 58 1/2 feet long)
The 2016 season jib sheet diameter was clearly too big - it was hard to fit through blocks, and was a little big for the winches. It was easy on the hands, though.

=== Traveler ===

The traveler is built of Harken "big boat" and HL (high load). The purchase is 4:1.

* track: 5 foot long Harken 32mm
* end controls: Harken 5170 with cam cleat
* car: Harken T3242B.HL

=== Boom Vang ===

* The boom vang was repaired in 2013. The spring and the vang tube were replaced.
* If necessary to adjust the vang to level the boom, first attach a topping lift to the boom (the main halyard will serve this purpose well). When the weight of the boom is held by the topping lift, remove the two 10-32 allen head cap screws that are located on either side of the vang tube near where the red indicator tab is in the vang tube slot. These allen head cap screws fit into a series of threaded holes in the inner aluminum thick walled tube that carries the red indicator tab. This tube serves as the stop for the main vang spring. Raise or lower the boom until the proper threaded holes line up with the clearance holes in the outer tube and re-install the cap screws.

== Sails Kept on the Boat==

General: The [[http://sailing.mit.edu/wikiupload/3/31/X_Dimension_Manual_of_Useful_Information.pdf Owners "Helpful Hints"]] has various advice in the pages 4-5 "Sail Control" section.

===Mainsail===

When not sailing, the mainsail is normally kept flaked on the boom with a sail cover.

While hoisting, reefing, or flaking the mainsail, the "lazy jacks" (E-Z-JAX system) can help contain it. See the [[Media:Lazy Jack Installation Instructions.pdf |E-Z-Jax system manual]] (untitled pdf) for operation instructions (page 4).

===Headsails===

The #3 Genoa (approximately 135%) is an older sail. Can be sheeted inside or outside the shrouds.

The #1 Genoa was purchased for the 2014 season.

There is a UV shield on the #1 and #3 genoas. Port side. Make sure it is exposed when the sail is left furled on the drum. The drum should roll clockwise when rolling in the sail.

The #4 jib/ heavy-weather jib was purchased for the 2016 season. There is no UV shield on this sail; please do not store it on the headstay.

===Spinnaker===

New for the 2016 sailing season is an asymmetric 'runner'.

== Sail Inventory (as of May 2016)==

=== Mainsails ===

The mainsail was purchased new prior to the 2014 season, and is on the boat during the sailing season and in the end bay of the pavilion off-season.

Storm Trysail

=== Jibs and Genoas ===

Genoa #1 was purchased new prior to the 2014 season, and is on the boat during the sailing season and in the end bay of the pavilion off-season. There is a UV shield on the Genoa, port side. Make sure it is exposed when the sail is left furled on the drum. The drum should roll clockwise when rolling in the sail.

Genoa #3 (tied with sail ties, but not in a sail bag)

There is a UV shield on the #1 and #3 genoas. Port side. Make sure it is exposed when the sail is left furled on the drum. The drum should roll clockwise when rolling in the sail.

A #4 jib/ Heavy-weather jib (satisfies ISAF HW jib definition): purchased new in Spring 2016. There is no UV shield on this sail; do not roller furl this jib - take it off the headstay.

Storm jib, new in 2013.

=== Asymmetric Spinnaker ===

We have a ~new asymmetric spinnaker as of Spring 2016. Shredded in June 2016. To be diagnosed, possibly repaired off season.

=== Symmetric Spinnakers ===

As of May 2015 we do not have the capability to fly symmetric spinnakers on the boat.

0.5 oz Tri Radial Symmetric Spinnaker (in North Sails blue bag dated 1979)

0.75 oz Symmetric Spinnaker (in North Sails blue bag)

1.5 oz Tri Radial Symmetric Spinnaker (in blue sail bag)

Three symmetric spinnakers (one of each weight) were relocated to S. Dynes' garage for hanging storage Oct 2013.

=== Sails We Used To Own ===

The original working main that came with the boat blew out at the end of the 2013 season. North Sails deemed it unrepairable.

A spare main, originally for the previous mast and unable to be mounted on the current mast without changing slugs. Discarded as part of a pavilion cleanup fall 2013.

Original Genoa #2. A panel split during the 2013 season; North Sails deemed it unrepairable.

Original Genoa #1. Various tears/holes during the 2013 season; North Sails deemed it unrepairable ("nothing to sew to'). Discarded as part of a pavilion cleanup fall 2013.

Working Asymmetric Spinnaker : blew out a panel at the end of the 2014 season, North Sails deemed it unrepairable.

== Companionway Hatch Removal ==

* Remove Forward Hatch Stop by removing three wood screws on the ceiling of the coach roof just forward of the companionway opening. Slide the stop out between the hatch and the coaming.

* Remove the wood screws holding the hatch rails to the hatch. All screws except the furthest forward screws will be accessible. Once these are removed, the rails may be rotated outboard and the hatch slid aft to access the last two screws. Remove the hatch.

== Steering ==

=== Helm ===

* The steering wheel is trapped by the fiberglass cover in the center of the cockpit. Remove this cover to remove the steering wheel.
* The emergency tiller is a long steel bar inserted into a square hole beneath an inspection portal in the fiberglass cover aft of the helm. The tiller is kept in the starboard lazarette.

=== Rudder ===

* When hauled in Nov 2011, the rudder was saturated with water. 4 holes were drilled to drain it over the winter, then plugged in May 2012.
* The rudder was pulled Dec 2011 and the shaft repacked. Prior to this time there was a steady trickle of water entering the boat from the rudder post.

== Thru-Hulls ==

As delivered to MIT in August 2011, X-Dimension had 11 thru-hulls. 
After Winter 2011/2012 refurb, the thru-hulls are:

* port v-berth 1.5" - blackwater out
* port forward of keel 1" - greywater out
* port mid-keel 0.75" - toilet in
* stbd mid-keel 0.75" - galley seawater
* port mid-keel 2" - speed impeller
* stbd mid-keel 2" - depth transceiver (epoxied in place)
* stbd aft of keel 1.5" - galley greywater out
* stbd mid cockpit 1" - engine in
* stbd cockpit 1.5" - scuppers
* port cockpit 1.5" - scuppers
* port cockpit 1/2" at waterline - propane drain

There are two vestigial thru-hulls, one for an impeller and the other for a depth transducer. These are located just aft of the main cabin forward bulkhead, beneath the cabinets.

In June 2013 another thru-hull was added:
* port v-berth 2" - combined speed paddlewheel/depth-sounder/water temperature

== Bilge Pumps ==

There are two electric bilge pumps and two manual bilge pumps. An electric submersible pump is in the central portion of the bilge well. A diaphragm electric pump is in the cabinet beneath the nav station. Float switches for the two electric pumps are located in the bilge well. The diaphragm pump's float switch is in the deepest part of the bilge; it should energize first and keep the bilge dry. The submersible pump's float switch is forward and higher; it should energize if there is an inch or more water in the bilge.

The two electric bilge pumps are connected to the House batteries via the always-on "Bilge Pumps" breaker on [[X-Dimension_systems#Circuit_Breaker_Panel_1|breaker panel #1]]. Individual auto-manual-off controls for the electric pumps are located port of the nav station. Note that the "Bilge Pumps" breaker bypasses the House Battery Switch and the pumps will still operate if the House Battery Switch is off. (See [http://sailing.mit.edu/wikiupload/3/3c/X-dimension_bilge_circuits.pdf X Dimension Bilge Pump Wiring])

The cockpit manual pump is located on the port bulkhead of the cockpit just forward of the helm. The high-volume manual pump is located under the floorboards of the hanging locker behind the nav station, and can be operated without removing the floorboards. The handles for the two manual pumps are stored in the hanging locker behind the nav station. The smaller handle fits the pump in the cockpit, and the longer handle the pump behind the nav station.

All bilge hoses exit the boat starboard of center at the transom.

=== Submersible Electric Bilge Pump ===

* Rule Bilge Pump 1500 Submersible (new in 2012)
* Specs: 12 DC; capacity 1500 GPH '''horizontal flow'''
* Rule-a-Matic float switch in bilge, just forward of the submersible pump
* Rule 3-Way lighted rocker panel switch by nav table

=== Diaphragm Electric Bilge Pump ===

* Jabsco Electric Diaphragm Bilge Pump Model: 34600-0000
* Specs: 12 DC; open flow capacity: 10.8 GPM (648 GPH)
* Rule-a-Matic float switch in deepest part of bilge, aft of the submersible pump
* Rule 3-Way lighted rocker panel switch by nav table

=== Cockpit Manual Pump ===

* Whale Gusher 10
* Repair kit is West Marine part # 255658 OR 135038

Maintained April 2017.

=== High Volume Manual Pump ===

* Edson Gallon-a-Stroke Model 117
* Order parts from Edson http://www.edsonpumps.com/pumps_acc/accessories_pg_02.php
Maintained March 2017.

'''Note:''' the high volume manual pump is operated with the long handle from inside the locker behind the nav station. The pump itself is underneath the floorboards in that locker; the handle is inserted into the pump through a cut-out in the floorboards on the starboard side of the locker (to your left when looking into the locker). The cutout may be covered by stored items, such as PFDs, which must be removed to access the pump.

=== Strum Boxes ===

* Strum boxes are 1 1/2" West Marine part # 100729, Whale mfg. part # SB5865

== Head ==

The head is a hand-operated marine toilet unit connected to a 25 gallon expanding holding tank. The output from the toilet goes into the holding tank. From the holding tank there are two hoses, one to a pump-out fitting on the deck, the other to a thru-hull under the forward cabin sink.

The forward facing panel beneath the sink in the forward cabin can be removed for access to the thru-hull valve.

The seawater in thru-hull is located port of center under the main cabin floorboards, just aft of the mast. A small mesh strainer is located inline soon after the thru-hull valve.

The toilet is Jabsco model 29090-2000 (compact bowl & seat).

= Electrical =

== 12-volt ==

=== Batteries ===

There are two independent sets of batteries on the boat. The "Engine" battery (or "Starter Battery") is used for starting the engine. The "House" batteries supply power to most of the rest of the electrical equipment onboard.

The House batteries are charged by the alternator. The Engine battery is charged via the Balmar Duo Charge, mounted on the bulkhead above and just forward of the House batteries. A solar panel was installed in 2015 to trickle-charge the house batteries.

==== Engine Battery ====

The Engine Battery is a marine dual-purpose AGM battery. The battery is located in the port lazarette, next to the water heater, and under the propane tank.

The Engine battery is isolated by the Engine Battery Switch, located alongside the circuit breakers above the galley sink. The Engine Battery Switch is an on/off switch, located by the circuit breaker panels above the galley sink.

When the Engine Battery Switch is on, power is connected to the starter motor and to the "Ignition Switch" on the binnacle in the cockpit through the always-on 50 amp "Engine" breaker above the galley sink. The Ignition Switch on the binnacle powers the following circuits:

* Starter button on binnacle (connected to starter solenoid)
* Balmar charging regulator
* Engine instruments in cockpit instrument panel
* Engine temperature sensors, oil pressure sensor and alarm buzzer
* Electric inline Fuel Pump located under port settee, just aft of the fuel tank

The Engine Battery Switch should be switched to OFF when leaving the boat.

==== House Batteries ====

The House battery bank consists of two Lifeline GPL-31T deep-cycle marine AGM batteries, tied together in parallel. This battery bank is located in the starboard lazarette, just aft of a bulkhead that separates the lazarette from the main cabin. The House battery compartment is usually covered by a white wooden tray that contains winch handles.

The House battery bank is isolated by the House Battery Switch, located alongside the circuit breakers above the galley sink.
The House Battery Switch is a four-way switch located by the circuit breaker panels above the galley sink. During normal operation of the boat, the House Battery Switch should be switched to the "House" position. This allows the house battery bank to be charged by the engine, and to power the various 12-volt devices through the breakers above the galley sink.

The House Battery Switch should be switched to "OFF" when leaving the boat.

The two additional positions on the House Battery Switch will enable parallel use of the House battery bank and the Engine battery, and should only be used in case of emergency. (See [http://sailing.mit.edu/wiki/index.php/Standard_operational_procedures#Emergency_Battery_Operations Emergency Battery Operations]) Note that the Engine Battery Switch must be ON in order to use the House Battery Switch as an emergency parallel switch.

=== Solar Charging ===

A 55-watt '''Ganz GSP-55 solar panel''' is installed on the v-berth hatch. The cable snakes through the dorade box into the head, then along the port wiring conduit. It connects to a '''Morningstar SunSaver MPPT solar controller''' which charges the House battery bank directly (not through the House Battery Switch).

=== Circuit Breaker Panels ===

As of September 2016, there are four circuit breaker panels above the galley sink, and one panel in the cockpit.

*'''Note''': Any circuits that are not currently connected will be labeled "N/C" with blue tape at the circuit breaker.

==== Circuit Breaker Panel 4 ====

As of September 2016, this Breaker panel is not being used. Some of the breakers may be used for other circuits in the future. Some of the space on the panel may also be used for ammeters in the future.

==== Nav Lights Fuse Panel ====

The dark grey plastic panel in the cockpit, starboard of the wheel, is a Blue Sea Systems "[http://bluesea.com/category/16/products/4306 WeatherDeck Waterproof Fuse Panel]". The navigation lights on the boat are controlled through this six-position panel.

Power to this panel is supplied by the "Navigation Lights Master" circuit breaker on the control panels above the galley sink. Each of the six circuits is protected by an internal blade-type fuse. When power is supplied to the panel, and the corresponding fuses are not blown, then the circuit indicator labels will glow red. When each circuit is switched on, then the label will glow green. If the label does not glow, then the fuse is probably blown. Please see the instruction manual for fuse replacement.

=== Cabin Lights ===

A bundle of Black/White/Red/Yellow #14 wire runs the length of the port and starboard sides of the cabin, with the starboard set extending into the v-berth. The "Cabin Lights" breaker feeds the White circuit with Black as the return. (Red for night lights and Yellow for foot lights are currently unused. One of these two may have been co-opted for the anchor light). Red night lighting is selected locally at each light fixture. Amperages are for brightest setting and are by manufacturer's specification, not observed.

== NMEA 2000 network ==

The NMEA 2000 network on ''X Dimension'' entirely consists of instruments, cables and connectors manufactured by Garmin. All connectors are NMEA 2000 "Micro" connectors. The network consists of a backbone that runs from the cabinet on the port side of the companionway to the top of the mast. The backbone requires a terminator at either end. The backbone also requires 12v DC power to operate; this is supplied by the yellow power cable.

The network consists of a backbone, and various "drops" that interface via "T-connectors". The drops on the network currently are:

* Garmin GMI 10 display
* Garmin GPSMap 541 chartplotter
* Yellow 12v DC power cable
* Garmin Intelliducer depth sounder
* Garmin GWS 10 wind instrument
* Vesper XB8000 Class-B AIS Transponder
* Arduino-based data logger

The GMI 10, GPSMap 541, and Vesper XB8000 have their own power connections. The depth sounder and wind instruments draw power from the network.

The network cables have five conductors:

* Red: +12v DC
* Black: Ground
* White: Data+
* Blue: Data-
* bare wire: shield

[[IMAGE:XD_compressor_2.jpg|thumb=XD_compressor_2_tn.jpg|right|Fridge Compressor (top)]]
[[IMAGE:XD_compressor_rear.jpg|thumb=XD_compressor_rear_tn.jpg|right|Compressor rear label]]

The refrigerator / ice box is located beneath the galley counter and can be accessed via two hinged hatches. There is a shelf in the refrigerator compartment that will accommodate ice blocks.

The refrigerator compressor is made by '''Alder/Barbour'''. The exact model is unknown but appears similar to the '''ColdMachine''' model.

The compressor runs on the 12V house battery and is located in the starboard lazarette outboard of the house battery box. The compressor is powered by a 15A breaker on breaker panel 2 above the galley sink. A thermostat in the ice box controls operation of the compressor.

The compressor has two blade type fuses located at the outboard aft corner:
* 15A Main
* 5A Fans

A diagnostic LED is on the rear panel; the cadence of the LED's flashing indicates the specific problem with the compressor.
