  • Patent number: 5595132
    Abstract: A catamaran vessel includes two hulls which are mutually connected by a cargo deck. A superstructure includes passenger spaces and is supported by a web structure which extends generally along each hull. Each longitudinal side wall of the superstructure is formed from a latticework beam whose plane is oriented generally vertically and whose longitudinal axis extends essentially horizontally. The latticework beams are fixedly connected to the wall structures. The floor and ceiling structures of the superstructure are connected to the latticework beams so as to greatly stiffen the superstructure and to render the beams highly resistant to bending forces. Consequently, the spaces defined between the longitudinal profiles of the beams and the struts are essentially free of deformation forces when the vessel is at sea. The spaces can be used essentially completely for windows, and the wall structures can be given a relatively low natural bending resistance.

  • Patent number: 5535690
    Abstract: A pitch stabilized vessel includes at least one displacement hull constructed for high propulsion speeds of, for instance, 35 knots. The hull is configured so as to locate the pitching center of the vessel far forwards on the hull, for instance, at a point corresponding to 75% of the length of the hull from the stern thereof. Generally horizontal and elongated fins extend along the hull and project out from the actual hull in the stern half thereof. The fins extend from the stern-edge of the hull through a distance corresponding to one-third of the length of the hull. The fins have a total horizontally projected surface area which corresponds to at least 5% of W/d, where W is the total underwater volume at construction draft and d is the hull construction draft.

  • Patent number: 5269245
    Abstract: A hull intended for multi-hull vessels for goods and passenger transport at speeds of, e.g., 30-50 knots is characterized in that the vertical distance from the base line of the hull to the center-of-gravity point of the volume of the underwater body of the hull, up to a water line corresponding to a normal hull draft, is over 55% of the hull draft defined between the base line (BL) and the water line (T) in the case of the stern half of the hull extending between the stern and midships.
