PROBLEM TO BE SOLVED: To provide a craft that has a ship shape capable of reducing pressure resistance and friction resistance, acting on a hull, without decreasing wake gain (propeller efficiency).SOLUTION: A craft 100 has a ship shape in which a beam is maximized in a maximum beam position C at a distance equivalent to 55-85% of a between-perpendiculars length Lpp being a distance between a stern perpendicular AP and a bow perpendicular FP, from a stern 15, and in which the beam is linearly decreased toward the stern 15, between the maximum beam position C and an inclination end position D at a distance equivalent to 25-42% of the between-perpendiculars length Lpp from the stern 15.

    【課題】伴流利得(プロペラ効率)を悪化させることなく、船体に働く圧力抵抗および摩擦抵抗を減少させることができる船型を有する船舶を提供する。【解決手段】船舶100は、船尾15から、船尾垂線APと船首垂線FPとの距離である垂線間長Lppの55〜85%の距離にある最大船幅位置Cにおいて、最も船幅が大きく、船尾15から垂線間長Lppの25〜42%の距離にある傾斜終了位置Dと最大船幅位置Cとの間において、船尾15に近づく程、船幅が直線状に小さくなる船型を有する。【選択図】図1
