<p>A vessel comprising a hull providing the floating power and having on the underside an upwardly re-entering hull recess and air supply means (31) for supplying pressurized air to the hull recess. Preferably the hull comprises at least two downwardly projection hull parts (22) extending in the longitudinal direction of the vessel and bounding between them the hull recess, whilst at least one flap body (25, 26) is connected with the hull so as to be movable between a rest position in which the flow resistance is at a minimum and a working position in which the hull recess is closed laterally in a manner such that it is open only on the bottom side. </p> |
