PURPOSE:To reduce a load applied to an engine and efficiently display power of the engine, by introducing air to a ship bottom from a suction port of a ship body and flowing the air in the direction of the ship bottom thus decreasing resistance in a part of the ship bottom. CONSTITUTION:Air is sucked from a suction port 1 provided in a position higher than a level of water and guided to a ship bottom part from a discharge port provided in a central ship bottom step part 2. This guided air equally flows in the stern direction by a ship rib (keel) 3 to decrease frictional resistance in the under water ship bottom part, obtain a sliding condition of the stern part from the center on air, assist a load to an engine, efficiently display power of the engine and increase a speed while improve sailing efficiency. |
