PROBLEM TO BE SOLVED: To enable a decrease in fuel consumption without spoiling marine navigation safety.SOLUTION: A ship 10 which obtains propulsive power by driving a normally-used propeller 11 with a main engine 12 is provided with an additional propeller 20 and its driving means. The additional propeller 20 is arranged at the bottom or at a bottom rise part that is a position different from an arrangement position of the normally-used propeller 11. An output of the driving means of the additional propeller 20 is 25% or less of an output of the drive means of the main engine, so that a normally-used operation state that the normally-used propeller 11 is driven to obtain propulsive power and an operation state that the additional propeller 20 is driven to obtain propulsive power can be selected.

    【課題】船舶の運航安全性を損なうことなく、燃料消費低減を図ることができるようにする。【解決手段】主機12により常用プロペラ11を駆動して推進力を得る船舶10に、追加プロペラ20及びその駆動手段が設けられ、前記追加プロペラ20は、前記常用プロペラ11の配置位置とは異なる位置であって、船底又は船底立ち上がり部に配置され、かつ前記追加プロペラ20の前記駆動手段の出力は、前記主機の駆動手段の出力の25%以下であり、常用プロペラ11を駆動して推進力を得る常用運転状態と、追加プロペラ20を駆動して推進力を得る運転状態とを選択可能である。【選択図】図3
