PROBLEM TO BE SOLVED: To reduce fuel consumption without losing the operation safety of a vessel.SOLUTION: A vessel for driving a usual propeller by a main engine to obtain thrust includes a vertical tunnel 30 formed in a bow part to penetrate a bottom, a horizontal tunnel 32 formed to communicate with the vertical tunnel 30, and an additional propeller device including an additional propeller 20 and its driving means 22. The additional propeller device is configured such that the additional propeller 20 is provided to turn around the vertical center line of the vertical tunnel 30, the additional propeller 20 can be lifted below the bottom and to the height position of the horizontal tunnel 32, and the additional propeller 20 is along the vertical tunnel 30 when it is at the height position of the horizontal tunnel 32.SELECTED DRAWING: Figure 1

    【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】主機により常用プロペラを駆動して推進力を得る船舶に、船首部に船底を貫通する上下トンネル30が形成され、上下トンネル30に連通して横方向トンネル32が形成され、追加プロペラ20及びその駆動手段22を含む追加プロペラ装置が設けられ、追加プロペラ装置は、その追加プロペラ20が上下トンネル30の上下方向中心線回りに旋回可能に設けられ、かつ、追加プロペラ20が船底より下方と、横方向トンネル32の高さ位置とに昇降可能に構成され、追加プロペラ20が横方向トンネル32の高さ位置にあるとき、横方向トンネル30に沿うように構成されている。【選択図】図1
