To provide a marine propulsion devise and a ship capable of recovering contraction flow energy generated by propeller rotation.SOLUTION: A marine propulsion devise comprises a propeller provided at the stern, and a duct located at least partially on the wake side of the propeller and with the centerline along the axis of the propeller rotation. The duct has an airfoil shape in the cross section including the centerline and the angle of the airfoil shape chord direction relative to the centerline is 5 degrees or less.SELECTED DRAWING: Figure 2

    【課題】プロペラの回転によって生じる縮流のエネルギーを回収可能な舶用推進装置及び船舶を提供する。【解決手段】舶用推進装置は、船尾に設けられるプロペラと、前記プロペラの後流側に少なくとも部分的に位置し、前記プロペラの回転軸に沿った中心線を有するダクトと、を備え、前記ダクトは、前記中心線を含む断面において翼型形状を有し、前記翼型形状のコード方向が前記中心線に対してなす角度が5度以下である。【選択図】 図2
