ABSTRACT:
A motor driven pump, located substantially at the center of mass of a boat and its fixed contents, is provided with a series of selectively effective, aligned openings for taking in water from a selected direction and discharging it in the same direction, so that the boat can be shifted at will forward, backward, sidewise or obliquely without substantially affecting the orientation of the keel of the boat. Provision is made for the utilization of the same pump (1) for pumping out and discharging bilge water; (2) for utilizing water from the body of water in which the boat floats to fight fires; and (3) for turning the boat through simultaneous utilization of disaligned intake and discharge passages. Provision is further made for the optional use of an auxiliary boat driving motor in the stern of the boat with slide member for smoothly covering and streamlining the auxiliary motor operating space when such motor is withdrawn therefrom.
