  8. CRP:Controllable-Reversible Pitch propeller • Blades pivot on axes radial to the propeller shaft • Pitch is determined by Blade angle • “Feathering” is Zero pitch • Negative pitch yields astern thrust • At constant engine RPM, ship speed is controlled by pitch • Speed = Pitch x RPM

  9. CRP propellers….. • ,,, are common with Gas Turbine propulsion and many Medium Speed Diesel propulsion ships • … are occasionally used with Slow Speed Diesels • … and are rare with Steam Turbine propulsion
