Provided is an apparatus for reducing added resistance of a ship. According to an embodiment of the present invention, in a ship in which added resistance is reduced by reducing pitch and heave motions of the ship in the long wavelength section of the wave, an apparatus for reducing added resistance of a ship comprises: a bow resistance reducing device mounted on a bow part of the ship; and a stern resistance reducing device mounted on a stern part of the ship. The bow resistance reducing device and the stern resistance reducing device may be mounted on the sides of the bow and stern parts so that the lift force acts upwards of the bow resistance reducing device and the stern resistance reducing device when encountering the wave.

    선박의 부가저항 저감 장치가 제공된다. 일 실시예에 있어서, 파랑의 장파장 구간에서 선박의 피치운동(pitch motion) 및 히브운동(heave motion)이 저감되어 부가저항이 감소된 선박에 있어서, 상기 선박의 선수부에 장착되는 선수부저항저감장치; 및 상기 선박의 선미부에 장착되는 선미부저항저감장치;를 포함하고, 상기 선수부저항저감장치 및 상기 선미부저항저감장치는, 파랑과 조우 시 상기 선수부저항저감장치 및 상기 선미부저항저감장치의 상방으로 양력이 작용하도록 상기 선수부와 상기 선미부의 측면에서 장착될 수 있다.
