Highly skewed controllable pitch propellers (CPPs) of the author's company's design and manufacture have been installed in nearly one hundred large passenger ships since their market introduction in 1977. This paper describes the main characteristics and design principles for this type of propeller. Some results from cavitation tunnel model tests relating to the propulsive and vibration excitation performance of high skew (HS) propellers are presented. Off-design considerations for special applications are briefly discussed as well as strength considerations for high skew propellers operating in ice. The essential service experience gained in full scale is summarised.
