WebbSkew is usually expressed as the circumferential displacement of the propeller tip made non-dimensional by the propeller diameter. Skew back evens out (to some extent) the influence of a highly non-uniform wake field and reduces peak values of propeller-induced vibrations. Modern ship propellers always have some skew back. • Rake iG. WebbRake can affect the flow of water through the propeller, and as implications with respect to boat performance.
