The latter houses at least one bladed device (10, 11). Said ledges (8, 9) incorporate two units arranged at opposite parts from the hull centreline. Bladed device (10, 11) is arranged at aft part of the ledge (8, 9). Besides, said ledge (8, 9) incorporates one or more lateral thrusting propellers (12, 12′, 12′′) to develop the water flow relative to said hull (1) between bladed device (10, 11) and craft hull, in lengthwise direction at the ledge (8, 9).
