Recently, in order to improve circumstances for sailor, reducing vibration and noise will be required.<BR>As a method of reducing a propeller induced force, Highly Skewed Propeller is investigated. This paper presents some aspects of Highly Skewed Propeller applied for controllable pitch propeller and then some advantages and test results regarding Highly Skewed Propeller are introduced by basing the investigations at DTNSRDC in the United States and our model test. Highly Skewed Propeller applied for controllable pitch propeller has backward and forward skew, in order to reduce spindle moment for blades without compromising the advantages of propeller skew (cavitation and vibration improvement) .<BR>Model experimental results and full scale results by KaMeWa propeller are presented which the advantages of Highly Skewed Propeller are confirmed for controllable pitch propeller, too.
