3 and 4 Wintons are directly connected to pumps and in addition are fitted with 4 - inch piping extending to the bilges of boat, enabling them to take suction and pump out water in case of a leak which the regular bilge pump will not displace. They are located, one each side of the boat while one will carry the entire electric load of the boat the other is in reserve in case of breakdown or overhaul. There are 3 12-volt auxiliary batteries for generators, radio, and stool pigeons. The bank of batteries also provided a 24-volt electric lighting circuit to all parts of the boat including navigation lights which can be used in case of emergency. One hundred gallons of lubricating oil is carried in reserve tank.
Fuel is supplied to each engine by gravity and fuel pump systems.
Generators are supplied y fuel pump system only. Each pump will furnish water to any part of the system and discharge is controlled by a hydraulic valve. All major gate valves controlling discharge from pumps to manifold and turrets are opened and closed by means of a hydraulically operated piston attached to the gate valve stem. The hydraulic system uses oil, but if a breakdown occurs the valves may be operated by either air or water pressure with the aid of by-pass valves. Electric driven blowers in engine room provide a change of air every five minutes, preventing an accumulation of dangerous gases and fumes.
