PROBLEM TO BE SOLVED: To suppress occurrence of disturbance in a flow near a rear end part of a skeg thereby improving propulsion performance.SOLUTION: A twin skeg ship 1A comprising: a hull 1a; skegs 2A, in a pair, which are provided on a stern hull 3 of the hull 1a at an interval; propeller shafts 8 which are supported by the respective skegs 2A in the pair and project from the skegs 2A toward a stern 1b side; and propeller s10 which are fixed to the propeller shafts 8 on the stern 1b side with respect to the skegs 2A. Each skeg 2A comprises: lateral faces, in a pair, which respectively continuously extend toward the stern 1b side and are connected to each other at ends on the stern 1b side, on both sides of a ship width direction; and upper rectification parts 20A which are at least a part of portions above the propeller shafts 8, and which are so formed as to gradually extend to the ship width direction outer side as a center line of the pair of lateral faces approaches the stern 1b side.SELECTED DRAWING: Figure 1

    【課題】スケグの後端部近傍における流れに乱れが生じるのを抑え、推進性能を改善する。【解決手段】ツインスケグ船1Aは、船体1aと、船体1aの船尾船体3に船幅方向に間隔をあけて設けられた一対のスケグ2Aと、一対のスケグ2Aにそれぞれ支持され、スケグ2Aから船尾1b側に突出するプロペラ軸8と、スケグ2Aよりも船尾1b側でプロペラ軸8に固定されたプロペラ10と、を備え、各スケグ2Aは、船幅方向両側に、船尾1b側に向かってそれぞれ連続して延び、船尾1b側の端部で互いに接続される一対の側面と、プロペラ軸8よりも上方の部分のうちの少なくとも一部で、一対の側面の中心線が、船尾1b側に向かうにしたがって漸次船幅方向外側に延びるよう形成された上部整流部20Aと、を備えている。【選択図】図1
