PROBLEM TO BE SOLVED: To reduce wave-making resistance by restraining wave height from increasing at a side rear end (corner part) of a water flow deflector, in a stern structure having the water flow deflector provided on a bottom surface of a stern.SOLUTION: A stern structure includes a hull, and a water flow deflector 16 which is provided integrally with the hull, which constitutes a part of a bottom 14 of a craft on the rear end side of the hull and which has a downward inclined surface. Front and rear edges of the inclined surface of the water flow deflector are gradually displaced posterior to the hull toward a lateral side from a central position in a width direction of the hull.SELECTED DRAWING: Figure 1
【課題】船尾底面に水流偏向体を備えた船尾構造において、水流偏向体の側部後端(角部)で波高が増大するのを抑えることで、造波抵抗を低減する。【解決手段】船体と、船体と一体に設けられ、船体の後端側にて船舶の船底14の一部を構成する、後ろ下がりの傾斜面を有する水流偏向体16とを備え、水流偏向体の傾斜面の前縁及び後縁は、船体の幅方向にて中央から側方へ向かうにつれて、徐々に船体の後方へ変位している。【選択図】図1
