PURPOSE: A lift fin and a ship having the same are provided to reduce the resistance of a hull because the submerged surface area of the ship is reduced by floating the hull with lift generated in the lift fin, and to reduce roll of the ship by adjusting the position of the lift fin. CONSTITUTION: A lift fin(10) generates lift to reduce resistance and roll applying to a hull, and comprises a multistage wing(12) and a turning part(14). One end of the multistage wing is hinge-coupled to the hull around a hinge shaft and is flexibly extended to a longitudinal direction. The rotating part vertically turns the multistage wing around the hinge shaft. |
