PROBLEM TO BE SOLVED: To provide a rudder, rudder unit and a marine vessel capable of reducing resistance during straight advancing of the vessel while maintaining the original performance of the rudder.SOLUTION: A steering comprises: a pair of rudder bodies 20 rotatably supported to a hull through respective rotary shafts, disposed on a right side and a left side across a center of a beam of the hull. When the rudder bodies 20 are attached to the hull, upper parts 20A are arranged with reference faces R being vertical and along a front and rear direction of the hull during straight advancing of the hull, and lower end parts 20B are disposed tilting toward outside of the beam.SELECTED DRAWING: Figure 3
【課題】舵本来の性能を得つつ、船舶の直進時の抵抗を低減する舵および舵ユニットならびに船舶を提供する。【解決手段】回転軸を介して船体に対して回転可能に支持される舵本体20が、船体の船幅の中央から左右にずれて一対設けられる舵において、舵本体20は、船体に取り付けられた場合に、上部20Aが船体の直進時に基準面Rが鉛直かつ船体の前後方向に沿って配置され、下端部20Bが船幅の外側に向けて傾斜して設けられる。【選択図】図3
