Sports and leisure watercraft 3 to 4 metres long of the single brace trimaran type, rigged as a catboat using a sailboard rigging, characterised in that the inside of its central hull is designed to receive therein the helmsman, in that it is designed to be totally controllable from inside its central hull, and in that its transverse stability is independent of the weight and of the position of the helmsman, who therefore does not have to exert any so-called righting positions.
