A propulsion apparatus for a ship in which two propellers rotate in opposite directions to generate propulsive force, and a ship equipped with the propulsion apparatus. The propulsion apparatus for a ship according to an embodiment of the present invention includes: a rear propeller fixed to a drive shaft; a front propeller rotatably supported on the drive shaft in front of the rear propeller; and a conversion driving device connected to a front propeller to rotate the front propeller in an opposite direction to the rear propeller and to convert a rotational force generated by the front propeller rotated by an external force into electric power.

    두 프로펠러가 상호 반대로 회전하며 추진력을 발생시키는 선박용 추진장치 및 이를 갖춘 선박이 개시된다. 본 발명의 일 실시예에 의한 선박용 추진장치는 구동축에 고정된 후방프로펠러; 후방프로펠러 전방의 구동축에 회전 가능하게 지지된 전방프로펠러; 전방프로펠러와 연결되어 전방프로펠러를 후방프로펠러와 반대로 회전시키고, 전방프로펠러가 외력에 의해 회전되어 발생되는 회전력을 전력으로 변환하는 변환구동장치;를 포함한다.
