Abstract:
1. In an improved means for integrating a water propulsion system into a ship, the improvement comprising: a first bow oriented water propulsor having a first bow oriented water inlet disposed, at least in part, proximal a lower forward portion of a bow of a main center hull of the ship and wherein, when the ship is moving forward and the first bow oriented water propulsor is operating, water taken into the first bow oriented water inlet generates a hydrodynamic force on a bow wave of said ship thereby reducing energy of said bow wave and wherein said first bow oriented water propulsor expels at least a majority of its discharge propulsive force water aft into a first open bottomed recess inset upward into the main center hull of the ship and wherein said first open bottomed recess is, at least in part, defined either side longitudinally by downwardly extending longitudinal portions of the main center hull and wherein a first open bottomed pressurized gas layer is formed in said first open bottomed recess and wherein said first open bottomed pressurized gas layer is supplied with gas from artificial gas pressurization means.
