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.

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 has been recently (09 March 2013) been repaired. The spring and the vang tube have been replaced. When the vang is installed, it will likely need adjusting to level the boom. This is accomplished by attaching 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.

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. 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.

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 "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.

Engine Battery

The Engine Battery (or "Starter 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.

When the Engine Battery Switch is on, power is connected to the starter motor and to the "Ignition Switch" on the binnacle through the "always on" 50 amp "Engine" breaker at the top of the galley breaker panels.

The Ignition Switch powers on 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

The Ignition Switch also sends power to the following circuit 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 Lifeline GPL-31T deep-cygle 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 on the breaker panel 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 to be charged by the engine and it allows the house battery to power the various 12-volt devices through the breakers on breaker panels 1, 2, and 3.

The House battery switch should be switched to "OFF" when leaving the boat.

The additional positions on the House Battery Switch should only be used in emergencies. Details for how to use the House Battery Switch in an emergency can be found in the File:XD Battery Switch Guide.pdf.

Circuit Breaker and Switch Panels

As of August 2012, There are four circuit breaker panels above the galley sink, and one switch panel.

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

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

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

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 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.
