PROBLEM TO BE SOLVED: To provide a propeller for a vessel capable of improving cavitation performance and propeller efficiency. SOLUTION: A maximum value of a camber is made to a shape positioned at a rear edge side more than 0.75 in a chord line direction (x/C), so as to restrain a high negative pressure peak value at a leading edge and delay initial generation of cavitation. The leading edge side of the camber is made small, and the trailing edge side is made large. The camber increment at the rear part is made large compared to the camber decrement at the front part, so as to enlarge a lifting force almost without changing resistance force and improve efficiency of the propeller.
