To provide a vessel propulsion device and a vessel capable of improving propulsion performance.SOLUTION: A vessel propulsion device includes: a plurality of ducts provided on a bottom of a hull and lined up in width direction crossing a front-rear direction of the hull; propellers arranged rotatably inside respective ducts and generating a flow in the front-rear direction inside the ducts; and a fairing material provided on at least one of a front side or a back side between the ducts, respectively continued with inner surfaces of ducts adjacent to each other, and having a pair of guide surfaces projecting in the front-rear direction from the ducts. A dimension of the fairing material in the width direction becomes smaller as it separates from the ducts in the front-rear direction.SELECTED DRAWING: Figure 4
【課題】推進性能を向上させることができる船舶推進装置、及び船舶を提供する。【解決手段】船舶推進装置は、船体の船底に設けられ、船体の前後方向に交差する幅方向に並ぶ複数のダクトと、ダクトのそれぞれの内部に回転可能に配置され、ダクト内に前後方向の流れを発生させるプロペラと、ダクト間の前側及び後側の少なくとも一方に設けられ、互いに隣り合うダクトの内面とそれぞれ連続するとともにダクトから前後方向に突出する一対の案内面を有するフェアリング材と、を備え、フェアリング材の幅方向の寸法は、ダクトから前後方向に離間するにしたがって小さくなる。【選択図】図4
