Backstay Adjuster

Sailtec Integral Backstay Adjuster (Model 10SI), 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.

Headsail Roller Furling System

Sails Kept on the Boat

General: The [Owners "Helpful Hints"] has various advice in the pages 4-5 "Sail Control" section.

Mainsail

Lazy Jack Installation Manual (no title) for the E-Z-JAX mainsail furling system. Page 4 of this manual gives operating instructions; the rest of the manual is e.g. parts identification and installation instructions.

The mainsail is normally kept furled on the boom with a sail cover.

Headsails

The #3 Genoa (approximately 135%) is normally kept on the roller furler.

The #1 Genoa is a carbon-reinforced racing sail that is normally kept in the forward v-berth and used for racing.

Spinnaker

The Asymmetric Spinnaker is normally kept in a spinnaker bag in the forward v-berth. It is equipped with a snuffer.

Note: Spinnaker pole storage on toe-rail requires periodic checking even on sails not using spinnaker, because of its current (Sep 2011) shortened length (see Ongoing Problems list.)

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.

Bilge Pumps

There are two electric bilge pumps and two manual bilge pumps. The primary electric is a diaphram pump located in the cabinet beneath the nav station. The secondary is a submersible located in the center portion of the bilge well. Float switches for these pumps are located in the bilge well. The primary manual is located in the port bulkhead of the cockpit just forward of the helm. The secondary manual is located under the floorboards of the foul weather gear locker. It can be operated without removing the floorboards.

Individual auto-manual-off controls for each electric pump are located port of the nav station. These are energized by the always-on bilge pumps breaker in the main breaker panel.

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

See the previous owner's Useful Info writeup, page 7, section headed "Bilge Pumps" for the previous configuration.

Strum Box

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).

Refrigerator / Ice Box

Fridge Compressor (looking forward)

Fridge Compressor (top)

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 refridgerator 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.

Stove

Freshwater

Electrical

12-volt

Batteries

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

Both banks of batteries are charged by the alternator through an ARCO BI-1602 battery isolator.

Starter Battery

The Starter battery is a marine high-current AGM battery (not intended for deep cycle use). The battery is located in the port lazarette, next to the water heater, and under the propane tank. The starter battery is isolated by the Starter Battery Switch, currently located in the starboard lazarette, above the House batteries. (This switch will likely be moved to the breaker panels above the galley sink before the boat is operational in summer 2012.)

When the Starter Battery Switch is on, power is supplied to the following circuits through the "always on" 50 amp "Engine" breaker at the top of the galley breaker panels:

Starter button on binnacle (connected to starter solenoid)
HEHR voltage regulator unit
Engine instruments in cockpit instrument panel
Engine temperature sensors and oil pressure sensor

The Starter Battery Switch also sends power to the following circuits through the "always on" 10 amp "Fuel Pump" breaker.

Electric inline Fuel Pump located under port settee, just aft of the fuel tank.

House Batteries

The House battery bank consists of two mixed-use AGM batteries (intended for starting and/or deep cycle use), connected in parallel. These batteries are 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 wooden tray that contains winch handles.

Misc

The best measure of the status of the house battery is to use the switch above the galley sink and toggle it to the right when the engine is stopped (i.e., not charging) and the battery switch is set to "House". There is a voltmeter near the switch that should indicate at about the red/green line. When the engine is running, the indicated voltage should ba approximately 14V. Note that the switch sometimes has a poor contact and needs to be jiggled a little to have it work. Note that the ammeter in the engine instrument cluster in the cockpit is not working.

110-volt

The 110v system is inoperative as of May 2012.

The shore power connector has been disconnected.
All the 110v breakers have been removed.
The wiring to the 110v outlets is still in place but is disconnected at the breaker panels.
Three 110v outlets (non-GFCI) are located:
- in the head
- 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 May 2012
There is an external zinc "guppy" that is deployed at the stern while the boat is on the mooring or at the dock.

Lightning Dissipation

The boat is fully grounded, with a woven copper strip connecting the mast, shrouds, and engine block.
The only bonding from the grounded systems to salt water is via the propeller shaft via the engine block.

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

The GMI 10 and GPSMap 541 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
