PURPOSE: A vessel is provided to collect a lost energy with a rotary current in a rearward of a propeller, and to prevent a decrease phenomenon of a propulsion efficiency of the vessel. CONSTITUTION: A vessel comprises a hull (110), a propeller (120), a rudder (130), a blade unit (140), and an energy recovery module (150). The propeller is combined rotatably with an end of a stern bulb (111) formed in a tail end of the hull, and generates a driving force for a propulsion of the hull. The rudder is combined in the hull in a position adjacent to the propeller, and controls a progressive direction of the hull. The blade unit is arranged rotatably in one side of the rudder towards the propeller, and is rotated by a rotary current in a rearward of the propeller in a rotation of the propeller. The energy recovery module is connected to the blade unit partially, and is arranged inside the rudder, and collects a generated energy in a rotation of the blade unit.
