とを特徴とするリアクションフィン。In front of the screw propeller at the stern, a plurality of fins are provided that protrude radially from a boss surrounding the propeller shaft and are formed so as to convert the direction of the flow flowing into the propeller into a direction opposite to the rotating direction of the propeller. In the reaction fins, the length of the fins arranged below the base line is shorter than the length of the fins arranged parallel to and above the horizontal base line passing through the center of the propeller, and A reaction fin characterized in that the fin tips and the fin tips and the stern frame are connected by reinforcing struts.
