PROBLEM TO BE SOLVED: To provide a ship steering device which can perform positioning control corresponding to influence of inertial force of a ship or disturbance thereof.SOLUTION: A ship steering device is provided in which movement control is performed to move a ship to a target coordinate based on a signal of a GPS device. Based on a distance from a target position, a movement control stopping zone Ar, a buffer zone Br adjacent to the movement control stopping zone Ar, and a movement control executing zone Cr adjacent to the buffer zone Br are configured. Generation of thrust by a propulsion unit of the ship for a movement control is stopped at the movement control stopping zone Ar. Generation of thrust by the propulsion unit of the ship for a movement control is executed at the movement control executing zone Cr. Only when the ship is stayed in the buffer zone Br after being moved from the movement control executing zone Cr to the buffer zone Br, and being moved away from the target position, generation of thrust is executed by a propulsion unit of the ship for movement control at the buffer zone Br.SELECTED DRAWING: Figure 7 【課題】船舶の慣性力や外乱の影響に対応した位置決め制御をすることができる操船装置を提供する。【解決手段】ＧＰＳ装置の信号に基づいて船舶を目標位置に移動させる移動制御を行う操船装置において、目標位置からの距離を基準として、移動制御停止帯域Ａｒと、移動制御停止帯域Ａｒに隣接している緩衝帯域Ｂｒと、緩衝帯域Ｂｒに隣接している移動制御実施帯域Ｃｒと、が設定され、移動制御停止帯域Ａｒにおいて、移動制御のための船舶の推進装置による推力の発生を停止し、移動制御実施帯域Ｃｒにおいて、移動制御のための船舶の推進装置による推力の発生を実施し、緩衝帯域Ｂｒにおいて、移動制御実施帯域Ｃｒから緩衝帯域Ｂｒに移動してきた後に緩衝帯域Ｂｒ内に留まっており、かつ目標位置から離間する方向に移動している場合にかぎり移動制御のための船舶の推進装置による推力の発生を実施する。【選択図】図７
