舶のリアクシヨンフイン。 In a propulsion system for a ship in which a propeller is installed eccentrically from the center of the ship on the side where the propeller blades descend when the propeller rotates forward, fins protrude radially from the fin boss surrounding the bossing in front of the propeller. A plurality of propeller blades are installed from near the side of the descending side to near the downward slope of the rising side, and the fins are twisted so as to change the flow of water in the opposite direction to the forward rotational direction of the propeller. A reaction fin for a ship, characterized in that it is provided with a.
