Engine Room

The engine room is accessible through a dedicated hatch in the mid cockpit. In the area forward of the engine there is room to access the engine front and sides. Inside the pilothouse is also a hatch that allows access to the area behind the engine, the shaft seal, and exhaust system.

Extensive sound insulation is present between the engine room and the pilothouse/salon. The engine room ventilation is through dedicated ports of large capacity and the intake is protected from taking water.

The engine room also houses the house battery bank, fuel tanks, water tanks, the waste tank and there is a dedicated location for the 120VAC diesel genset.

Machinery and Tanks

Standard power is the Betamarine B85T which produces 85hp at 2,800rpm. The shaft is equipped with a dripless shaft seal and two cutlass bearings. The propeller is a 22" diameter four blade type for optimum efficiency. The engine uses a water lift muffler with dry stack riser to prevent raw water entering the engine.

Fuel is drawn from either tank, each of which has its own fuel filter / water separator. The total standard fuel capacity is 200 USG which can be expanded with an auxiliary tank. There are two fuel fills on deck, one for each wing tank. Tank level indicators are provided at the helm. Tanks are controlled by a crossover valve to allow fuel management.

A hydraulic steering system with an 18" wheel is located at the starboard helm station. SeaPiper is equipped with a standard bow & stern thruster.

In an emergency the rudder can be hand controlled by a manual tiller fit through to the cockpit deck hatch. A hydraulic bypass valve is incorporated in the hydraulic system to allow this control.

SeaPiper is equipped with two stainless steel wing tanks for fresh water 80 USG, with its own pressure pump and deck fill plate. The freshwater systems provide approx. 30 psi of hot and cold water to the galley, and head/shower. The waste tank is in the engine room forward and is equipped with a deck pump out plate overboard discharge with seacock and electric diaphragm waste.

Electrical

SeaPiper is equipped with two electrical systems: one for 12VDC and one for 12Vac. The house battery bank is configured for (2) 6V Group L16 sized batteries (400Ah each) and these batteries are connected into a 12V system. This house battery is connected to an AC inverter/charger to generate the 120Vac on board. In the pilothouse a MASTER battery switch is located that enables the 12V house battery to power SeaPiper's 12V system.

SeaPiper is equipped with a well laid out custom 12V circuit breaker panel and a 120Vac circuit breaker panel. An onboard battery charger is provided and is connected directly to the shore power connection, and this charges the house battery bank as well as the starting battery. The starting battery can be connected in parallel to the house battery bank by means of the MASTER battery switch.

There is a total of six (6) 120Vac outlets provided on board. For serviceability and to enable easy modifications wiring that is located behind panels is generally run through conduit. All wiring is Marine Grade stranded and tinned wire and labeled where appropriate.

Ventilation

All accommodations have extensive passive ventilation through dedicated ventilators, in addition to opening ports, hatches and opening doors.

Materials

The SeaPiper 37's hull and superstructure is of resin infused vinylester construction providing better fiber to resin ratio, stronger laminate, lower void content and a reduction in VOCs (gasses) emitted during construction.
