The invention discloses an anti-swing full-rotation tugboat capable of enhancing course stability. The tugboat comprises a boat body and a bilge keel is arranged at the bilge part of the boat body; aventral fin is arranged at the center of the bottom of the boat body; and the bilge keel and the ventral fin extend along the front-back direction of the boat body. According to the anti-swing full-rotation tug capable of enhancing course stability, the bilge keel and the ventral fin are arranged at the same time to form the transverse and vertical bidirectional water pressing effect, so that boosting vortex damping is triggered; and thus on the basis of improvement of the anti-swing performance and the running stability, the reaction to rotation flexibility and ship speed increase is avoided,so that the comprehensive performance of a ship is improved.
本发明公开了一种抗摇及加强航向稳定性的全回转拖轮,包括船体,所述船体的舭部设置有舭龙骨,所述船体的底部中心设置有腹鳍,所述舭龙骨和所述腹鳍沿所述船体的前后方向延伸设置。本发明的一种抗摇及加强航向稳定性的全回转拖轮,通过同时设置舭龙骨和腹鳍,从而,形成横向、竖向的双向压水效果,引发助推性的漩涡阻尼,进而,在提高抗摇性能和行驶稳定性的基础上,避免对回转灵活和船速提升起反作用,从而,提高船舶的综合性能。
