The technical field of the invention is that of ship building, more particularly making ship hulls. A monohull with stern stabilizers, also known as a pseudo-trimaran, for constituting a very high-speed ship comprises a central float (1) and two shorter side floats (2) situated towards the stern of the central float (1) and connected thereto by faired link arms (5); according to the invention, the underwater portions of the three floats (1, 2) are always immersed at least in part and regardless of speed, with the side floats (2) having tiltable underwater foils (3) and with the fineness coefficients of the three floats lying in the range 0.25 to 0.35, with ratios of length over beam lying in the range 12 to 20, and with the ratio of the length of the central float over the length of the side floats lying in the range 2.5 to 4.5.

[ What is claimed is:] [1.]1. 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.
