Three (3) propellers were newly designed for the container ship on which comparatively large pressure fluctuation of higher order blade frequencies (2nd5th) was observed. 1) The following concepts were applied in the new propeller design in order to decrease the propeller tip-vortex cavitation, consequently to decrease the pressure fluctuation of higher order blade frequencies, without changing the number of propeller blades. (1) Tip-unload (2) Smaller diameter (3) Increase of blade area (4) Increase of skew Model experiments were performed in the cavitation tunnel by using these propeller models. These propellers were evaluated after investigating the repeatability of the fluctuating pressure and the effects of the number of propeller revolutions (at the test) and the cavitation number on the fluctuating pressure. The fluctuating pressure of one (1) of these propellers was found to have decreases by about 40 % on average.
