Abstract
Disclosed is a method of controlling a rotational speed of a propeller of a ship to reduce cavitation. The method may reduce cavitation by determining a rotational angle range of a propeller corresponding to a cavitation occurrence section when cavitation occurs during sailing of a ship and by increasing or reducing the rotational speed of the propeller within the determined rotational angle range of the propeller corresponding to the cavitation occurrence section. Therefore, it is possible to simply reduce cavitation only by controlling the rotational speed of the propeller without changing the structure of the propeller.
