【摘要】 船舶在弯曲航道航行时需改向航行，为了减少船舶回转中的船速损失，使船舶基本沿着计划航线改向航行，采取根据船舶改向旋转半径，按合适的回转角速度改向操纵法，可能是最理想的方法更多还原

【Abstract】 Ships need to alter course on meander faisway.In order to reduce the loss of ship’s speed,and keep ships alter course along planned course,it may be the most favourable way to manoeuvre ships according to the radius of turning on altering course and a proper angular velocity.更多还原
