PROBLEM TO BE SOLVED: To provide a ship type which reduces wave-making resistance in a high speed vessel having a sea speed of a Froude number 0.32 or greater.SOLUTION: A ship type has a shape in which, in a shape of load water line, width is gradually narrowed in a curved manner from an SS6 position backward, and it is the narrowest at 1/2 position of SS4 and formed to be 90% of the maximum width, and toward the rear side from there, the width is widened gradually in a curved manner, and the width is the widest at an SS3 position, and also, at each position between the SS6 position and the SS3 position, the width below the load water line does not become wider than the width at the load water line. Thereby, in a region from the SS6 position to the SS3 position especially in a high speed region in which a Froude number is 0.32 or greater while a ship body is travelling, a pressure drop phenomenon occurred in a conventional ship type is alleviated and a so-called wave valley becomes small, so that a wave-making phenomenon generating around the ship body is also alleviated. Therefore, an effect can be acquired in which a wave-making resistance reduces, and accordingly, a main machine horse power required for propelling the ship body is further reduced than that of the conventional ship type.SELECTED DRAWING: Figure 14

    【課題】フルード数が0.32以上の航海速力を有する高速船において、造波抵抗を低減する船型を提供する。【解決手段】満載喫水線の形状を、SS6位置から後方に向けて徐々に曲線状で幅を狭め、SS4 1/2位置で最も狭くして最大幅の9割幅に形成し、それより後方に向けては徐々に曲線状で幅を広げて、SS3位置で最大幅に形状し、且つSS6位置とSS3位置間の夫々の位置で満載喫水線より下方の幅が満載喫水線での幅より広がらない形状の船型とすることで、船体が航走しているとき特にフルード数が0.32以上の高速域でSS6位置からSS3位置間の領域において、従来船型で見られた圧力低下現象が緩和されて所謂波の谷が小さくなることで船体周りに発生される造波現象も緩和され、その為に造波抵抗が低減し、それに伴い船体の推進に要する主機馬力も従来船型より低減される効果が得られる。【選択図】図14
