Re: Fixed vs folding prop

We recently switched from a 2 blade fixed to a 3 blade Max prop.. the difference is remarkable and percentage wise much higher in the light air 3-4 knot boatspeed range than the powered up 5-6+ knot range. We probably reach our optimum upwind speed now in 5 knots less wind than before, and can ghost along at 3-4 knots where 2-3 would have been it before.

The feathering props do away with the folders' reverse issues, and 3 blades is much less vibration under power too... but at a cost, of course ($$$)
