The present invention provides a ship propulsion apparatus, which is possible to collect axial flow energy generated by rotation of a propeller, and a ship. The ship propulsion apparatus comprises: a propeller formed on a stern portion; and a duct at least partially positioned on a wake side of the propeller and having a central line along a rotating axis of the propeller, wherein the duck has a wing shape with respect to a cross section having the central line and has equal to or less than 5 degrees of an angle formed by a code direction having the wing shape with respect to the central line.

    (과제) 프로펠러의 회전에 의해 발생하는 축류의 에너지를 회수 가능한 선박용 추진 장치 및 선박을 제공한다. (해결 수단) 선박용 추진 장치는, 선미에 형성되는 프로펠러와, 상기 프로펠러의 후류측에 적어도 부분적으로 위치하고, 상기 프로펠러의 회전축을 따른 중심선을 갖는 덕트를 구비하고, 상기 덕트는, 상기 중심선을 포함하는 단면에 있어서 날개형 형상을 갖고, 상기 날개형 형상의 코드 방향이 상기 중심선에 대해 이루는 각도가 5 도 이하이다.
