Propane System The propane system supplies two internal units, a Force 10 Three-burner Gimbaled Stove with Oven, and an Bosch Instant hot-water unit in the pilothouse. There is an aft locker for two cylinders in the lazarette, which has drains to the outside as required, in case of leaks. Each tank has a 12 volt solenoid, which has a switch on the 12 volt panel in the engine room. The certified hoses are one piece from the tank to each unit. There is an additional tank and hose for the BBQ.
