ABSTRACT:
The boat control system of the invention is a propulsion system for controlling the direction of passage of a vessel underway at low speeds. Six thruster nozzles are installed around the hull so that, used individually or in combinations, the boat can be maneuvered forward, backward, laterally or turned on its axis. The impeller pumps are operated by a water cooled reversible DC electric motor which allows the thruster apparatus to operate for long periods.
