A water inlet opening (6) is provided in the wall of this elongated capacity (4) oriented towards the bow of the craft and maintained in the open condition, in order to have the water back pressure prevailing in this elongated capacity (4) as soon as the craft is moving in the forward direction, said elongated capacity (4) being then at least partially filled with water.
