The present invention is to provide an apparatus capable of improving a degree of measurement about added resistance in waves by reducing a component of a first wave force in total resistance of waves to measure the total resistance of waves with an appropriate volume of a dynamometer when performance of a ship in waves is evaluated through a model test. To achieve this, the present invention provides an apparatus for measuring added resistance in waves, which comprises: a moving unit placed on a towing tank and connected with a model ship and a connection rod to be moved back and forth in accordance with front and rear agitation of the model ship; a restriction unit installed in the moving unit and partially restricting movement of the moving unit; and a dynamometer installed to the connection rod and measuring total resistance of waves which is applied to the model ship. 본 발명은 파랑 중 선박의 성능을 모형시험을 통해 평가함에 있어서 파랑중전체저항에서 1차파력의 성분을 감소시켜 적절한 용량의 동력계로 파랑중전체저항을 계측할 수 있도록 함으로써 결과적으로 파랑중부가저항 계측의 정도를 향상시킬 수 있는 장치를 제공하는 것을 목적으로 한다. 상기한 목적을 달성하기 위하여 본 발명은, 예인전차에 위치하며 모형선과 연결봉으로 연결되어 상기 모형선의 전후동요에 따라 전후로 이동하는 이동부; 상기 이동부에 설치되어 상기 이동부의 이동을 부분적으로 구속하는 구속부 및; 상기 연결봉에 설치되어 상기 모형선에 작용하는 파랑중전체저항을 계측하는 동력계;를 포함하는, 파랑중부가저항 계측 장치를 제공한다.
