。 In front of the screw propeller at the stern, a plurality of front fins are provided that protrude radially from both sides of the hull in order to twist the flow of water flowing into the screw propeller in the opposite direction to the rotation direction of the screw propeller. In addition, between the front fin and the screw propeller, a radial projection is provided from the stern boss surrounding the propeller shaft in order to twist the flow of water flowing into the screw propeller in the opposite direction to the rotation direction of the screw propeller. A plurality of rear fins are provided, and a central portion of the plurality of front fins as a whole is larger than a central portion of the plurality of rear fins as a whole in a propeller blade movement direction during forward rotation of the screw propeller. A double-type reaction fin characterized by being set so that it can be shifted slightly.
