Bulkheads and Framing
* resin used for construction is vinyl-ester except where noted.
- All bulkheads and support elements affixed to the hull are made of composite material (Coosa Board, resistant to rot).
- All major and minor bulkheads/framing elements were initially tacked in with methacrylate structural adhesive before final glass tabbing.
- Major bulkheads that separate compartment spaces are of 1.5 inch BW 26 Coosa Board and are tabbed in with at least 4 layers of 1708 biaxial glass, staggered every two inches, over a 0.75 inch foam fillet.
- Minor support and framing elements are of 0.75 inch BW 26 Coosa Board, tabbed with three layers of 1708 biaxial glass, staggered every two inches, with a finger laid fillet of silica thickened resin.
- all wiring uses ABYC approved tinned stranded copper wiring (Ancor or Cobra brand)
- butt, ring, and battery lug connectors are sealed with heat-shrink (either supplied with the connector or added separately)
- all voltages for house loads are 24 VDC except where noted
- house electric power distribution (24VDC and 12VDC) is provided with Mastervolt distributed power components (Masterbus)
- general electrical components (buss bars, power posts, breakers, panels, etc) are of BlueSeas brand.
- all wiring is, at minimum, 16 AWG (except where noted). CAT5e is used for Masterbus network communication.
- raw water is supplied by a once inch seacock that feeds a strainer/manifold
- three taps from the manifold, each with a ball valve, supply raw water to the necessary systems
- the strainer/manifold is valved such that the water supply can be shutoff, and fresh water be directed through the strainer/manifold for the purpose of flushing raw water systems with fresh water
Fresh and Raw Water
- Fresh water is supplied by three stainless steel tanks, center (35 gallons), port and starboard wing (XX gallons)
- Each tank can be completely isolated with each tank having a ball valve on the intake and discharge side
- Fresh water is pressurized with a pressure pump/pressure tank system
- Fresh water is pulled through two filter cartridges
- Raw water is pressurized with a 1.9 GPH pressure pump.
Supply and Distribution
- cold,hot and raw water is distributed via SeaTech polypropylene tubing and compatible fittings (a metric version of ‘PEX’, often used for houshold plumbing)
- The SeaTech plumbing routes through a central manifold, where each branch of plumbing throughout the boat can be shut off
- hot water is produced with an ITR Zephyr heating system (also supplies hydronic space heating)
- raw, cold and hot water supplies: forward head/shower, aft cabin sink, galley sink
- Toilet discharge can be directed to a 27 gallon holding tank, or direct overboard
- Toilet flush water can be selected from pressurized raw or cold fresh water
- Holding tank can be emptied via deck fill or pumped (electric) direct overboard
- Forward head shower sump can be pumped into black water holding tank, or direct overboard
- Main galley sink can be diverted into 16 gallon holding tank (in bilge, center section), or direct overboard
- Aft cabin sink empties directly into 16 gallon holding tank
- Appliance (washer, dishwasher) empties into 16 gallon holding tank, or direct overboard
- three forced air radiators are installed throughout: aft cabin, forward head, main/forward salon
- the coolant is heated with an ITR Zephyr heating unit and distributed to the radiators via marine grade heater hose
- The ITR unit includes an expansion and overflow tank, the heating circuit can be bypassed via valves to disconnect cabin heating while still providing domestic hot water
- Fuel is diesel stored in three main tanks: center (XX gallons), port and starboard wing (YY gallons each)
- Fuel fill can be isolated to any one, or all, main diesel tanks by opening/closing a ball valve for each main taink
- There are two ‘day’ tanks of 13 and 17 gallons
- Fuel can be polished/transferred to and from any one of the five tanks, through a 120 gph Racor dual filter, via 2.6 GPM transfer pump
- There are three send/return lines from the filter assembly, with individual shutoff valves, to supply necessary devices
