Abstract:
A hull for a high-speed vessel, the hull comprising a central main float and two side floats of shorter length situated towards the stern of the central float, said side floats being connected to said central float by link arms, the three floats having underwater portions which remain under water at all speeds, the underwater portions of the side floats having foils, the three floats having fineness coefficients in the range 0.25 to 0.35 with a ratio of length over beam lying in the range 12 to 20 and a ratio of central float length to side float length in the range 2.5 to 4.5, the link arms being faired in the form of airplane wings having a mean chord and a height above the water which is between one-half and one-fourth of the mean chord, thereby creating two ground-effect nozzles between the link arms, the abovewater side surfaces of the central float, the side floats, and the surface of the water on which said hull is moving.
