PROBLEM TO BE SOLVED: To provide a ship steering device which can perform fixed point holding control effective and with good accuracy.SOLUTION: A ship steering device 7 for a ship 100, which can perform fixed point holding control, and in which in the case that during performing fixed point holding control, a distance deviation from a target position is larger than a specified value and a travel quantity of the ship per a unit time is equal to or less than a specified quantity, or in the case that such a state that an azimuth deviation from a target azimuth is larger than a specified value and a turning quantity is equal to or less than a specified quantity is continued during a specified time or longer, a set value of a thrust for fixed point holding control at the time of these determination is stored as a reference value, and the reference value is added to an inputted set value of a thrust for fixed point holding control.SELECTED DRAWING: Figure 6
【課題】効率的且つ精度よく定点保持制御を実施できる操船装置を提供する。【解決手段】定点保持制御を実施可能な船舶100の操船装置7において、定点保持制御を実施する間に、目標位置からの距離偏差が所定値よりも大きい場合、且つ、単位時間当たりの船舶の移動量が所定量以下である状態が所定時間継続している場合、或いは、目標方位からの方位偏差が所定値よりも大きい場合、且つ、単位時間当たりの船舶の回頭量が所定量以下である状態が所定時間継続している場合に、これらの判定時点における定点保持制御の推力の設定値を基準値として保存し、入力される定点保持制御の推力の設定値に基準値を加算する。【選択図】図6
