を特徴とする、舶用推進効率向上装置。 It has multiple fins protruding radially from the fin boss that surrounds the propeller shaft of the propeller at the front of the screw propeller at the stern, and the fins are twisted so as to bend the flow of water in the opposite direction to the forward rotation direction of the propeller. At the same time, it is equipped with rectifying fins that can rectify the flow flowing into the fins.
A marine propulsion efficiency improving device, characterized in that the rectifying fin projects radially from the fin boss and is joined to the front edge of the fin.
