PURPOSE:To secure such a ship that is good in a feeling of boarding comfortableness as sailing on the surface of the water at super-high speed, by situating a lifting center of the ship more rearward than the center of gravitation, and constituting it so as to cause a hull nose part alone to come into contact with the surface of the water at the time of sailing. CONSTITUTION:A main wing 2 provided with a propulsive machine of a propeller or the like is attached to both sides in the rear of the hull 1, and dynamic lift at the main wing 2 is increased in proportion as a sailing speed is upped by drive of the propulsive machine, whereby the hull 1 is made so as to be floated up. At this time, a lifting center A is set to be more rearward than a gravitational center B whereby a rear part alone of the hull 1 is made so as to be floated as leaving a part of the gravitation left behind on a hull nose part 3. And afterward, the hull 1 should be sailed while making the hull nose part 3 contact with the surface of the water. During this sailing, if the dynamic lift grows larger than the specified value and the main wing 2 comes to be lifted up, the hull 1 is lifted up at the rear part alone and an angle of elevation of the main wing 2 is made smaller, so that it loses the dynamic lift, going down to a fixed angle, thus it comes to being stable in consequence.
