PROBLEM TO BE SOLVED: To provide an inward-inclined bow shape that enables an in-wave resistance increase to be reduced without damaging smooth underwater traveling performance and a large inward-inclined shape to be easily obtained, a vessel with the inward-inclined bow shape, and a method for designing the inward-inclined bow shape.SOLUTION: The bow shape of a hull 10 of a vessel has an inward-inclined shape 20 in which a part of a stem line 11 of a bow of the hull 10 is retreated and a part of the hull 10 is inclined inward. The shape of the stem line 11 is set so that a static water-level elevated position which is a position of a rising water surface occurring during smooth underwater traveling where there is no wave generated by a sea speed set as a representative speed generated in the bow during vessel sailing for each vessel during designing can be within the range X of the upper surface 11A of the retreated stem line 11.SELECTED DRAWING: Figure 1
【課題】平水中走行性能を損なうことなく波浪中抵抗増加を減少させることができ、また、大きな内方傾斜形状を容易に得ることができる内方傾斜船首形状、内方傾斜船首形状を有した船舶、及び内方傾斜船首形状の設計方法を提供すること。【解決手段】船舶の船体10の船首形状であって、船体10の船首部のステムライン11の一部が後退して船体10の一部が内方に傾斜した内方傾斜形状20を有し、船舶の航行時に船首部に生じる船舶毎の代表的な速度として設計時に設定されている航海速力によって波のない状態である平水中を走行する時に生じる水面の盛り上がり位置である静的水位上昇位置が、後退したステムライン11の上面部11Aの範囲X内にあるようにステムライン11の形状を設定した。【選択図】図1
