Zusammenfassung:Disclosed is a propeller for a vessel. The propeller has a cap fin, and thus is capable of controlling a hub vortex, recovering propulsion force which is lost by the hub vortex, and is desirable in terms of noise and vibrations. The cap fin divides loads of propeller blades. Therefore, the pitch angle of the propeller blades can be reduced. Accordingly, the propeller blades efficiently function for a cavitation, and a cap fin can be formed into a wing form to amplify lift force, improve the efficiency of the propulsion system, and reduce fuel consumption.
