The invention provides a gate rudder capable of reducing energy consumption of a ship in navigation. In a gate rudder having a pair of rudders composed of a left rudder and a right rudder disposed on both sides of a propeller at a stern, the rudders are formed by a first rudder portion extending in a left-right direction and a second rudder portion extending in a straight line in an up-down direction in a rear view. The rudder chord length of the second rudder part in the front-back direction is 40%-100% of the diameter of the propeller, the propeller is arranged between 15%-65% of the rudder chord length from the front edge of the second rudder part in the side view, and the propeller is arranged between 15%-65% of the rudder chord length from the front edge of the second rudder part in the side view. A rudder shaft for driving the rudder is arranged at a position which is 30-50% of the length of the rudder chord from the front edge of the second rudder part.

    提供能够降低船在航海中的能量消耗的门舵。在具有由配置在船尾的螺旋桨的两侧的左舵和右舵构成的一对舵的门舵中,在后视观察时,由沿左右方向延伸的第1舵部和沿上下方向呈直线状延伸的第2舵部形成所述舵,将所述第2舵部的前后方向的舵弦长度形成为所述螺旋桨的直径的40%~100%,在侧视观察时,将所述螺旋桨设置在从第2舵部的前缘起舵弦长度的15%~65%之间,在侧视观察时,将对所述舵进行驱动的舵轴设置在从所述第2舵部的前缘起舵弦长度的30%~50%的位置。
