To improve redundancy in a main engine in a vessel.SOLUTION: A vessel 1A includes: a hull 2; a main engine 3; an output shaft 34; a propeller 42; a propeller driving shaft 4; a motor 5; and a shaft connection/disconnection unit 7. The main engine 3 is provided in the hull 2. The output shaft 34 is rotated and driven by the main engine 3. The propeller 42 is provided outside the hull 2. The propeller driving shaft 4 rotates the propeller 42. The motor 5 is provided on the propeller driving shaft 4 and rotates and drives the propeller shaft 4. The shaft connection/disconnection unit 7 disconnects the output shaft 34 and the propeller driving shaft 4.SELECTED DRAWING: Figure 1 【課題】船舶における主機の冗長性を高める。【解決手段】船舶１Ａは、船体２と、主機３と、出力軸３４と、プロペラ４２と、プロペラ駆動軸４と、電動機５と、軸連結断続部７と、を備える。主機３は、船体２内に設けられる。出力軸３４は、主機３により回転駆動される。プロペラ４２は、船体２の外部に設けられる。プロペラ駆動軸４は、プロペラ４２を回転させる。電動機５は、プロペラ駆動軸４に設けられ、プロペラ駆動軸４を回転駆動させる。軸連結断続部７は、出力軸３４とプロペラ駆動軸４とを断続する。【選択図】図１
