The paper aims at propeller design techniques which suppress inception of tip vortex cavitation. Model tests provide insight in the phenomena associated with tip vortex cavitation inception on propeller blades and the important parameters are systematically varied and investigated. The application of this work is primarily directed to improvements on naval propellers. However, lessons learned are also useful in the design of propellers for merchant ships, where there is a risk of cavitation hindrance due to vibrations or noise.
