  • Ship hull construction
    Patent number: 4802427
    Abstract: A ship hull construction comprises an upper main hull having a keel and three submerged substantially cylindrical sub-hulls, one sub-hull being located directly beneath the keel of the main hull, the other two sub-hulls being located above and to opposite sides of said one sub-hull, each sub-hull being mounted to the underside of said main hull and imparting buoyancy thereto, whereby the sub-hulls produce an advantageous hydraulic lift that softens entry of the main hull and dampen pitch, roll and yaw.
