Rigging

Standing Rigging

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. Cross check the headstay sag. In moderate winds, the headstay should have very little sag.

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.)

Current Inventory of Sails at the Pavilion (as of 02/09/2012)

Deck

Winches

When delivered to MIT in August 2011, X-Dimension sported 15 winches. After winter refurb January 2012, X-Dimension has 13 winches.

Traveler

Machinery

Power Train

GENERAL NOTE: The "Engine & Drive" section, pp. 5-6, of the previous owner's "Useful Info" has some data about the power train and how to operate it.

Engine and Transmission

TEMPORARY NOTE: The Perkins engine SHOP and PARTS manuals are available only as web copies as listed in the | documents list. As of now (30Aug11) we are verifying their dates when printed relative to our engine's age, and looking for a complete parts manual.

TEMPORARY JOTTINGS OF PRINCIPAL COMPONENTS

  • ENGINE: Perkins 4-108 diesel (4-cyl, 50-hp), new in 1989
  • Serial # ED70058U630095P (mfg 1987)
    (ED=4.108; 70058=parts list Nr; U=mfg UK; 630095=engine S/N; P=1987)
  • TRANSMISSION: Newage gearbox, approx 10 yrs old (at 2011)

Coupler, Stuffing Box and Cutlass Bearing

Propeller

  • PROP: Max-Prop feathering 2-blade propeller, unknown size/pitch/model#/etc
    • QUESTION: We found aboard (Sep11) a pamphlet for 3-blade prop, but "Useful Info" paper says she has a 2-blade prop.
    • Some water-damaged paper aboard has: MAX PROP Three Blade COL|__NS, 5-20-96, where "|__" looks a little like a down-arrow followed by room for 1 or 2 digits/characters.
      HEY!! Want to bet the "COL..." printing is "COLLINS"? ... as in the previous owner of the boat!?

Other Power Train Components

  • MUFFLER: Vernalift (unidentified model & mfgr) Thomasville, GA
  • FUEL SUB-SYSTEM:
    • Emergency fuel cut-off: ToBeFound
    • Filler deck fixture & Filtering: TBF
    • Primary fuel filter / water separator : on stbd lazarette bulkhead; Racor 500 FG S/S;
      inlet screen (TBFound)
    • Primary fuel lift pump: location: TBD (only germane if TBD has manual pump feature)
    • Tank:
      • Capacity: 40-gal, giving approx 288 miles @ 2000 RPM using 0.9 gal/hour
        giving 6.5 kt (per "Useful Info" doc p.5).
      • Material/when Installed/Replaced: TBF
    • Fuel gauges:
      • There is a mechanical fuel gauge located under the port main saloon bunk cushion.
        It is quite accurate when the boat is level.
      • The electrical fuel gauge(s) are not operative.
        TODO: define location(s)

Steering

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 - blackwater out
port forward of keel - ?
port mid-keel 1.5" - greywater out
port mid-keel 1" - toilet in
stbd mid-keel 1" - unused (formerly generator in?)
stbd mid-keel 2" - depth transceiver
stbd aft of keel - galley greywater out
stbd mid cockpit - engine in
stbd cockpit - scuppers
port cockpit - scuppers
port cockpit 3/4" at waterline - propane drain


Bilge Pumps

See the previous owner's Useful Info writeup, page 7, section headed "Bilge Pumps".
NOTE, however, that the control of these two pumps has been changed at MIT (>=14Sep11).


  • Forward Bilge: (between main saloon bunks)
    • Jabsco Model 34600-Series Electric Diaphragm Bilge Pump
    • Jabsco catalog shows Model 34600-0000 as their 12-volt DC version
    • This a high-capacity pump, actuated by a switch above the sink, powered by the "house" 12-v batteries. The "house battery must be 'on' for this switch to energize the pump.
    • There is a bilge float switch that turns on the pump when the water level in the bilge activates the switch, powered thru an inline fuse by the "house" batteries.
    • The pump is located under the nav table in a locker, and a hose into the bilge, and a strumbox (filter). Accessing the pump's check valves is easy to clear out small bits of crud that get past the strumbox.
    • The Jabsco bilge pump is plumbed to an outlet at the stern just above the waterline.
    • The in-line fuse is rated for 15 amps and the fuseholder is adjacent to the connection at the positive terminal of the house battery bank.
    • TODO: verify that we DON'T have a switch any longer (mid-Sep11) in the 12 v power to pump
    • TODO: we need specified inline fuse info: slo-blow?, size
    • TODO: state whether we have anti-siphon loop (since outlet "just above waterline"


  • Aft Bilge: (at bottom of companionway steps)
    • NOTE: see DISCUSSION of this pump (Fall 2011) brought on by several issues, and by the temporary situation of the rudder post leak.
    • Rule model 25S 500 GPH automatic bilge pump
    • This pump's purpose is to pump out a dammed zone between the engine and the bilge pump, i.e. to pump water leaking between the rudder post and the thru-hull tube.
    • The pump's design causes it to operate every 2-1/2 minutes, and pumps as long as water is present; otherwise, if no water is present, it turns itself off and runs again in 2-1/2 minutes. It is powered thru a dedicated inline fuse by the "house" batteries.
    • Specified fuse: 2.5 amp; current 1.0 amp @ 12v, 2.5 (sic) @ 13.6v
    • the automatic 2.5 minute cycles use c. 2 amp-hr/day with no water pumped


Head

X Dimension Blackwater System

The head is a standard Jabsco hand-operated marine toilet unit connected to a very small (~5 gallon) holding tank. The output of the toilet routes through an anti-siphon loop directly to a through-hull valve. The holding tank seems to have been added as a retro-fit. A T-fitting is inline above the through-hull which routes the waste through a gate valve and then into the holding tank. By lifting the teak lid next to the sink in the forward cabin vanity, one can see the hose and valve to deflect sewage into the small holding tank or overboard. The forward facing panel beneath the sink can be removed for easier access to the holding tank and the valves. The coupling for pump out is located near the valve assembly. Pump out stations have several coupling styles and can match as necessary.

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

NOTE: At the present time (09/13/2011), the head is configured to deflect sewage overboard; the gate valve to the holding tank is stuck closed and the seacock is stuck open. The head is currently placarded "Head Inoperative Do Not Use"

Refrigerator / Ice Box

  • The refrigerator / ice box is located beneath the galley counter and can be accessed via two hinged hatches
  • The refrigerator compressor runs on the 12V house battery and is located in the starboard lazarette outboard of the house battery box
  • The switch for the refrigerator compressor is located in the panel above the galley sink
  • The current draw of the refrigerator compressor is not known (as of 10/5/2011) so the refrigerator should only be run when the engine is charging the battery
  • There is a shelf in the refrigerator compartment that will accommodate ice blocks

Stove

Freshwater

Electrical

12-volt

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

Anti-Electrolysis

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

Electronics

TEMPORARY NOTE (02Sep11): The block tabulation of electronics documentation below will probably finally reside in the [Documents] section of this wiki.
The list is here primarily because some Electronic Wiz found many web hits on current manuals, and then a paperwork slog related onboard documents to the devices too.
