PURPOSE:To reduce the resistance against sailing by constructing the ship bottom between guide blades on both broadsides under a hull to be inclined downward toward the stern for floating up the hull by the air acting to the inclined face at the time of high-speed sailing. CONSTITUTION:On both broadside under a hull 1, a pair of plate-shaped guide blades 2 are provided from the bow to the stern, while on the central bow part between these guide blades 2, an expansion part 3 and auxiliary blades 4 are furnished. The expansion part 3 and a ship bottom part 7 between auxiliary blades 4 and guide blades 2 are shaped to be inclined downward from the bow toward the stern. At the time of stopping or low speed, the hull 1 sails as the hull of displacement sunk in water, while at the time of high speed, the air sucked from the bow works to the ship bottom inclined face 7 to generate a floatage, and the hull is floated up. At the time of high-speed sailing, the resistance against sailing can be reduced by gliding in a supported state by guide blades.
