Hi all, “White heather ” based at Port Edgar has a three bladed prop and is raced each week in Div 2. I allow the prop to spin free when racing ,believe this gives me an extra 1/2 knot in windy weather?????

Santana has a three bladed prop now fitted with a rope stripper (see photo).
I would differ from Brian in believing it best to lock the prop shaft when sailing by putting the engine in gear to stop the blade spinning. Just think of how a sycamore seed slows its descent by spinning, or a helicopter can descend after engine failure by auto-rotating.
