Shrew, a folding prop was the first that crossed my mind. I had deep discussions with the skillfully prop maker Flexifold in Denmark. But when he realized that the foldig would be placed in the streaming water after the big prop(stopped or slowley turning) he took all his calculations back and told me "it will not work".
Then a folding would has proplem to go out in reverse and it could jeopardize to get a heavy boat to stop.
No one could tell the pitch to this application.
The Autostream feathering prop is bigger 18", compaired to Flexifold 17" and Volvo Penta proposals 16".
An other advantages is adjusting the pitch in the water guite easy from the swimladder.
After sea trail I'm pleased how this prop works in forward, stop and in reverse. The drag is not more than a folding may be less according to Autostream.
