Anchors

  • 230 feet of white 3-stranded rode in blue basket, single black mark every 10 feet, double or triple mark every 50 feet
  • 90 feet of blue/orange polypropylene 3-stranded rode
  • 100 feet of beige 3-stranded rode
  • big Danforth anchor with 10 feet of chain attached
  • smaller CQR anchor

Rigging

Mast and Boom

  • Total length of mast: 63' 11.5"
  • Height of mast above deck: 57' 0.5"
  • Height of lower spreader above deck: 22' 0.5"
  • Height of upper spreader above deck: 41' 2.75"
  • Height of foredeck light above deck: 25'
  • Distance from base of mast to deck: 6' 11"
  • Distance from base of mast to foredeck light: 31' 11"

Standing Rigging

Shrouds and Spreaders

Standing rigging on the mast was inspected in detail March 2016. All rod rig fittings were removed, mushroom ends cleaned and regreased and reassembled except for the port lower spreader cup - there's one sticky set screw that cannot be loosened. Red threadlocker was used where appropriate. As a result of the inspection the upper starboard shroud (from the lower spreader to the masthead) was removed and taken to the riggers, where the lower end was cut off, the ferrule replaced, and a new head formed. The rigger said this was a non-standard size; he thinks it is not a Navtec rod but another make. He says a size 15 die (not a usual Navtec size) is the best match.

During the inspection everything seemed fine except the ferrules for the upper ends of the upper diagonals (lower spreaders to upper spreaders) could not be freed from the rod; the heads looked fine. Again, the port lower spreader cup could not be disassembled.

The rigger that we used: Kevin at NorthEast Rigging, 978-287-0060, http://nerigging.com/.

Headstay and Backstay

A Harken Mark III (Unit Size 2) headstay roller furling system is installed on the headstay. The drum should roll clockwise when rolling in the headsail. Owner's manual can be found at [1]

The backstay has a 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.

Running Rigging

Halyards

  • Main halyard: 125' long x 1/2 " (core unknown). As of Feb 2016 we have two in good condition.
  • Jib halyard: 125' long x 7/16" dia. with hi-tech core with no creep. As of March 2016 we have two in good condition, one new (solid green color) as of March 2016.
  • Spinnaker halyard: One 125' long x 7/16" dia. with hi-tech core (creep OK), one 125' long x 7/16" dia. of Sta-Set new as of March 2016.
  • Spinnaker pole topping lift: 95' long x 3/8" dia of Sta-Set. No need for a high-tech core here. New as of March 2016.

The covering of many of the jib/spin halyards is worn about 20' from the snap shackle, which would be about the level of the upper spreaders when the halyards are attached to a sail and tensioned. Inspection in March 2016 indicated that the screws holding the birdlines above the upper spreaders are the likely cause - these were too long and protruded inside the mast. They were set to a length that was flush with the inside of the mast and locked with nuts on the outside of the mast prior to launch in April 2016.

Sheets

  • 2016 season main sheet: Main sheet 52' x 9/16" measured
  • 2016 season jib sheet: 58' x 3/4 " measured (remeasured: 58 1/2 feet long)

The 2016 season jib sheet diameter was clearly too big - it was hard to fit through blocks, and was a little big for the winches. It was easy on the hands, though.

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 was repaired in 2013. The spring and the vang tube were replaced.
  • If necessary to adjust the vang to level the boom, first attach 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.

Sails

Sails Kept on the Boat

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

Mainsail

When not sailing, the mainsail is normally kept flaked on the boom with a sail cover.

While hoisting, reefing, or flaking the mainsail, the "lazy jacks" (E-Z-JAX system) can help contain it. See the E-Z-Jax system manual (untitled pdf) for operation instructions (page 4).

Headsails

The #3 Genoa (approximately 135%) is an older sail. Can be sheeted inside or outside the shrouds.

The #1 Genoa was purchased for the 2014 season.

There is a UV shield on the #1 and #3 genoas. Port side. Make sure it is exposed when the sail is left furled on the drum. The drum should roll clockwise when rolling in the sail.

The #4 jib/ heavy-weather jib was purchased for the 2016 season. There is no UV shield on this sail; please do not store it on the headstay.

Spinnaker

New for the 2016 sailing season is an asymmetric 'runner'.

Sail Inventory (as of May 2016)

Mainsails

The mainsail was purchased new prior to the 2014 season, and is on the boat during the sailing season and in the end bay of the pavilion off-season.

Storm Trysail

Jibs and Genoas

Genoa #1 was purchased new prior to the 2014 season, and is on the boat during the sailing season and in the end bay of the pavilion off-season. There is a UV shield on the Genoa, port side. Make sure it is exposed when the sail is left furled on the drum. The drum should roll clockwise when rolling in the sail.

Genoa #3 (tied with sail ties, but not in a sail bag)

There is a UV shield on the #1 and #3 genoas. Port side. Make sure it is exposed when the sail is left furled on the drum. The drum should roll clockwise when rolling in the sail.

A #4 jib/ Heavy-weather jib (satisfies ISAF HW jib definition): purchased new in Spring 2016. There is no UV shield on this sail; do not roller furl this jib - take it off the headstay.

Storm jib, new in 2013.

Asymmetric Spinnaker

We have a ~new asymmetric spinnaker as of Spring 2016. Shredded in June 2016. To be diagnosed, possibly repaired off season.

Symmetric Spinnakers

As of May 2015 we do not have the capability to fly symmetric spinnakers on the boat.

0.5 oz Tri Radial Symmetric Spinnaker (in North Sails blue bag dated 1979)

0.75 oz Symmetric Spinnaker (in North Sails blue bag)

1.5 oz Tri Radial Symmetric Spinnaker (in blue sail bag)

Three symmetric spinnakers (one of each weight) were relocated to S. Dynes' garage for hanging storage Oct 2013.

Sails We Used To Own

The original working main that came with the boat blew out at the end of the 2013 season. North Sails deemed it unrepairable.

A spare main, originally for the previous mast and unable to be mounted on the current mast without changing slugs. Discarded as part of a pavilion cleanup fall 2013.

Original Genoa #2. A panel split during the 2013 season; North Sails deemed it unrepairable.

Original Genoa #1. Various tears/holes during the 2013 season; North Sails deemed it unrepairable ("nothing to sew to'). Discarded as part of a pavilion cleanup fall 2013.

Working Asymmetric Spinnaker : blew out a panel at the end of the 2014 season, North Sails deemed it unrepairable.

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

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.

Circuit Breaker Panel 1

# Name Amps Power Source Notes
1 BILGE PUMPS 25A House Battery Powers both bilge pumps. Bypasses the House Battery Switch. LEAVE THIS BREAKER ON AT ALL TIMES
2 ENGINE 50A Starter Battery Switch Powers the starter button, the engine instruments, and the alternator regulator. LEAVE THIS BREAKER ON AT ALL TIMES
3 FUEL PUMP 10A Ignition Switch Powers the inline electric fuel pump. No longer necessary for operation of the engine as of Summer 2014

Circuit Breaker Panel 2

This is a "normal" circuit breaker panel in that all of the circuits are fed by the House Battery Switch. This panel contains the circuits that are most likely to be used most of the time during sailing trips. The breaker names and their rated amperage are listed below:

# Name Amps Notes
1 NAVIGATION LIGHTS MASTER 10A Supplies power to the Navigation Lights switch panel (see below).
2 NAVIGATION INSTRUMENTS 10A Supplies power to the Garmin GPSMap541 chartplotter, the Garmin GM10 display unit, the AIS transponder, and instruments on the NMEA2000 bus.
3 VHF RADIO 10A Supplies power to the fixed-mount VHF Radio located at the navigation station.
4 RADAR 5A Supplies power to the RADAR display unit and the RADAR antenna.
5 HORN 5A Supplies power to the horn (the button is located on the binnacle).
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.

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
  • Arduino-based data logger

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

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.
