ABSTRACT:
Presented is a water propulsion system for ships that enhances the efficiency of both the water propulsor(s) and the ship itself. This is accomplished by location of water inlet(s) for the water propulsor(s) to take advantage of water flow characteristics around a secondary bow of the ship and also proximal a stern of the ship. A primary object is to reduce the energy of the bow and/or stern waves of the ship and hence reduce the ship's wave making resistance. A secondary object is to reduce the frictional resistance of the ship. The water propulsors are preferably electrically driven with built in stator field windings and armatured rotors. A bow oriented water propulsor(s) would preferably have its discharge into a gas cavity in the underside of the ship. Both bow oriented and stern oriented water propulsor(s) would optimally have steering and/or reversing mechanisms.
