PROBLEM TO BE SOLVED: To provide a ship steering device which can easily determine a prescribed amendment factor regardless of a physical relationship of a side thruster and a forward/backward propeller with respect to centroid of the ship and a shape of the ship.SOLUTION: A ship steering device of a ship 100 comprises: a forward/backward propeller 4 to which power is transmitted through a propeller shaft 4a; and a side thruster 6 which generates thrust in a crosswise direction of the ship 100. The ship steering device includes a joystick lever which instructs propulsion direction of the ship 100 and magnitude of the thrust by inclination direction and inclination angle. Traverse thrust by the side thruster 6 is generated according to inclination operation of the joystick lever, a first amendment thrust by the forward/backward propeller 4 is generated according to turning operation of the joystick lever to cancel the rotation moment generated by the traverse thrust, and a first amendment factor is determined to calculate the first amendment thrust with respect to the traverse thrust.SELECTED DRAWING: Figure 4 【課題】船舶の重心に対するサイドスラスタと前後進プロペラとの位置関係および船舶の形状に関わらず容易に所定の補正係数を決定することができる操船装置を提供する。【解決手段】プロペラシャフト４ａを介して動力が伝達される前後進プロペラ４と船舶１００の左右方向の推力を発生させるサイドスラスタ６とが設けられる船舶１００の操船装置において、船舶１００の推進方向と推力の大きさとを傾斜方向と傾斜角度で指示するジョイスティックレバーを備え、ジョイスティックレバーの傾斜操作に応じたサイドスラスタ６による横移動推力を発生させ、横移動推力によって発生する回転モーメントを打ち消すようにジョイスティックレバーの回転操作に応じた前後進プロペラ４による第１補正推力を発生させ、横移動推力に対する第１補正推力を算出するための第１補正係数を決定する。【選択図】図４
