PROBLEM TO BE SOLVED: To provide an automatic ship position retaining boat capable of easily adapting even when characteristics such as size, shape and how it is drifted by wind which are unique to a boat are changed and retaining the boat automatically to a constant point offshore.SOLUTION: An automatic ship position retaining boat 1 is installed with a motor 3, a battery 4 and a controller 5 inside a hull 2 and a wind direction and wind velocity sensor 6 is attached to a top unit of the hull 2. A propeller 8 is connected to a motor 3 through a propeller shaft 7 and functions as an electric propulsion device 9. A unique dynamic behavior of the hull 2 is learned and stored to the controller 5 as an initial set value, the size of propulsion of the electric propulsion device 9 and fore and aft propulsion directions are automatically controlled by the controller 5 adjusting to the wind direction and the wind speed detected by the wind direction and wind speed sensor 6 and the ship position is retained.SELECTED DRAWING: Figure 1

    【課題】ボートの大きさ、形状、風による流され方等の、ボートに固有の特性が変わっても簡単に対応でき、自動的にボートを洋上の一定地点に保持することが可能な自動船位保持ボートを提供する。【解決手段】自動船位保持ボート1には、船体2の内部にモーター3、バッテリー4、制御器5が設置され、船体2の上部には風向風速センサー6が取り付けられている。モーター3にはプロペラーシャフト7を介してプロペラー8が接続されており、電動推進器9として機能する。船体2の固有の運動特性が学習されて初期設定値として制御器5に記憶され、電動推進器9の推力の大きさと前後の推進方向が、風向風速センサー6によって検知される風向と風速に合わせて制御器5により自動的に制御されて船位保持がなされる。【選択図】図1
