  • Ship hull
    Patent number: 6112687
    Abstract: A ship hull comprises at least one longitudinally directed displacement body which is symmetric to the longitudinal axis of the ship and which is adjoined by gliding surfaces at least at both longitudinal sides or, as the case may be, on all sides, being provided at the underside of the hull. The quantity of water displaced by the displacement body substantially corresponds, with respect to weight, to the total weight of the ship, so that the gliding surface lies substantially horizontally and on or in the vicinity of the surface of the water. The gliding surfaces are constructed in a wave-shaped manner in the longitudinal direction and, as the case may be, also in the transverse direction of the ship hull, wherein the wave shape of the gliding surfaces is displaced by approximately 180.degree. relative to the natural waves generated by the displacement body, so that the natural waves are virtually canceled during travel through the water.

  • Method of making a ship's hull
    Patent number: 4662299
    Abstract: A plank assembly for the formation of a ship's hull comprises interengaging hooks in only line contact with one another and enabling angular displacement of the two planks about an axis. The planks are also provided with arcuate flanges centered on this and bolted together and with attachment flanges enabling the planks to be secured to transverse ribs of the ship's hull.

  • Boat hull and method of making same
    Patent number: 4565146
    Abstract: A ship hull is formed of a plurality of transverse and generally parallel ribs and a plurality of side-by-side plank-forming and generally parallel elongated profiles each having two generally parallel londigitudinal edges abutting the edges of the adjacent profiles. One of the edges is formed with an inwardly extending flange engagng the ribs. Thus the flanges stiffen the profiles. Screw fasteners extend through the flanges and into the transverse ribs for securing the profiles to the transverse ribs. Seals form watertight joints between the abutting longitudinal edges of the profiles.
