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 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 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 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.

6	FRESH WATER PUMP	10A	Supplies power to the fresh water pump. Do not turn it on if the fresh water tank is empty.

Circuit Breaker Panel 3

This is a "normal" circuit breaker panel in that all of the circuits are fed by the House battery switch. The breaker names and their rated amperage are listed below:

#	Name	Amps	Notes
1	CABIN LIGHTS	30A	Supplies power to the various cabin lights onboard.
2	STEREO	15A	Will supply power to the AM/FM/CD-Player stereo system.
3	PROPANE	5A	Will supply power to the propane tank solenoid valve circuit, necessary for operation of the propane stove. Note that, in addition to this circuit breaker, a switch above the stove must be turned on to activate the propane solenoid.
4	FRIDGE	15A	Supplies power to the 12-volt compressor used to chill the refrigerator.
5	BILGE BLOWER	15A	Turns on the bilge blower.
6	12V AUX SOCKETS	10A	Will supply power to 12-volt "cigarette lighter" type sockets. Three in the cabinet with the back of the GPS, two at the nav table, one in the radar/radio bay, and one in the v-berth.

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 "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.
