。 A reaction consisting of a fin boss fixed to a stern frame in front of the propeller, and a plurality of fins that protrude radially from the fin boss and are tilted or twisted so as to bend the flow of water in the opposite direction to the rotational direction of the propeller. The wing is provided with a fin, and when the ship is traveling forward, the blade of the propeller is located diagonally below and in front of the fynbos on the side where the blade of the propeller rises, and in front of the fynboss diagonally above the fynbos with the side where the blade of the propeller descends. A propulsion performance improving device for a ship, comprising a rectifying propeller that rotates in a direction opposite to the rotational direction of the propeller to generate forward thrust.
