性能向上装置。 In a propulsion performance improvement device for a ship, in which a plurality of fins protrude radially from the fin bosses surrounding the bossing in front of the propeller and are twisted so as to change the flow of water in the opposite direction to the rotational direction of the propeller. A fin that projects obliquely upward from the lower edge of the rudder horn and a fin that projects almost horizontally from the rudder near the lower edge of the rudder horn on the propeller axis are provided on both sides, and the fins are twisted. A ship propulsion performance improvement device characterized by:
