Hull-less boat comprising three buoyancy elements 1 arranged at the apices of an isosceles triangle whose axis of symmetry is the axis of the boat. The buoyancy elements 1 have a symmetrical profile of least hydrodynamic resistance and the shape of the vertical plane of symmetry is a trapezium whose large base is at the top parallel with the water line and with the axis of the boat and the small base at the bottom, the leading edge making an angle greater than 30 DEG with the vertical. The buoyancy elements 1 are connected by the superstructure 3, 4 in a star or triangularly parallel to the water line 2 and distanced from the water surface by a value similar to the draught. At least one of the buoyancy elements 1 is equipped at the rear of its submerged part with a rudder 10. On the superstructure and above each buoyancy element 1 a sail 8 is mounted. <IMAGE>
