Provided are a stern rectification structure and a vessel capable of improving the efficiency of a propeller by rectifying a water intake flowing toward a propeller surface with the stern rectification structure installed in the stern of a vessel body, capable of improving propulsive performance by increasing thrust applied to the stern rectification structure in case of rectification, and structurally durable. The stern rectification structure is composed of an L-shaped stern rectification plate (5A) and a thrust generation assisting member (5B). The L-shaped stern rectification plate (5A) is installed to protrude from an outer plate of the stern of the vessel body (2) of the vessel in a widthwise direction of the vessel body and composed of a base plate unit (10) extended in the widthwise direction of the vessel body and a bent part (13) installed in an end of the base plate unit (10) in the widthwise direction of the vessel body and bent upward. The thrust generation assisting member (5b) is installed between the lower side of the L-shaped stern rectification plate (5A) and the vessel body (2) to allow the outer part to be inclined upward at an angle (1) larger than 0, but not exceeding 45.

    [과제] 선체의 선미에 설치한 선미정류구조에 의해 프로펠러면에 유입하는 흐름을 정류하는 것에 의해, 프로펠러의 효율을 보다 높이는 것과 함께, 정류할 때에 선미정류구조에 작용하는 추력성분을 보다 크게 해서 추진성능을 보다 향상하는 것이 가능한 것과 함께, 구조적으로도 견고한 선미정류구조 및 선박을 제공한다. [해결수단] L자형 선미정류판(5A)과 추력발생보조부재(5B)로 이루어지고, L자형 선미정류판(5A)을, 선박(1)의 선체(2)의 선미의 외판상에 선체폭방향으로 돌출해서 설치되고, 선체폭방향으로 연장된 기판부분(10)과, 이 기판부분(10)의 선체폭방향의 단부에 설치된 위쪽으로 꺾여진 절곡부분(13)을 갖고서 구성하는 것과 함께, 추력발생보조부재(5B)를 L자형 선미정류판(5A)의 하부와 선체(2) 사이에, 경사각도(α1)를 수평에 대해서 외측이 위쪽으로 향하는 각도로 0도보다도 크고 또한, 45도 이하로 해서 설치하여 구성한다.
