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 [http://sailing.mit.edu/wikiupload/3/31/X_Dimension_Manual_of_Useful_Information.pdf  Useful Info] writeup, page 7, section headed "Bilge Pumps" for the previous configuration.

=== Primary Electric ===

* Jabsco Model 34600-Series Electric Diaphragm Bilge Pump
* Rule-a-Matic float switch

=== Secondary Electric ===

* Rule 1500 GPH submersible bilge pump
* Rule-a-Matic float switch

=== Primary Manual ===

=== 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 ==

[[IMAGE:XD_compressor_1.jpg|thumb=XD_compressor_1_tn.jpg|right|Fridge Compressor (looking forward)]]
[[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 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.

=== 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.  (It is indended that this switch will be moved to the breaker panels above the galley sink some time in 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 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 one mixed-use (intended for starting and/or deep cycle use) AGM battery. This battery 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.

* Note: Prior to May 2012, two house batteries were connected in parallel.  One of these two batteries was found to be unable to hold a charge, so it was removed.

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.

In an '''emergency''', the House battery could possibly be used to start the engine by switching the House Battery Switch to "Both".  This will tie the House batteries and Starter battery together in parallel.  It is unknown whether or not this will cause fire or explosion.  Please only try this in an emergency.

In an '''emergency''' the Starter battery could possibly be used to power 12-volt devices onboard, such as the VHF radio, by switching the House Battery Switch to "2".  Please only try this in an emergency.


=== 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 table at the circuit breaker.

==== Nav Lights Switch Panel ====

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

Power to this panel is supplied by the NAVIGATION LIGHTS MASTER circuit breaker on breaker Panel 1.  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 the 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.

== 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
* White: Data+
* Blue: Data-
* bare wire: shield


== Radar ==

* JRC RADAR1000 mounted display
* installed in cubby over Nav Station table
* antenna mounted on pole on port quarter.
