In the last episode of Boat TechTV we looked at the cornerstone of marine propulsion - the fixed pitch propeller. However there are many areas of Naval Architecture where the use of a fixed pitch propeller is not suitable or good enough. One good example of this is sailboat propellers. This episode looks at feathering sailboat propellers and in particular Autoprop feathering sailboat propellers.
