PURPOSE: A transformable rudder of a vessel is provided to achieve precise and quick steering by reducing the area during high-speed traveling and increasing the area during low-speed traveling or in an emergency. CONSTITUTION: A transformable rudder of a vessel comprises a rudder body(110), a transformation member(120), and a transformation drive part(130). The rudder body is installed in order that the direction is converted for steering of a hull. The transformation member is installed in the rudder body and slides to protrude from or retract into the rudder body. The transformation drive part makes the transformation member protrude from or retract into the rudder body. |
