Just to update on my new Varifold prop: I did question the Varifold people about the pitch of the new prop before I ordered it. I thought a 15 x 10 would be better than 15 x 9. Varifold told me that the 15 x 9 would give me 6.4 knots +- at 2900 rpm. When I delivered from the winter yard to my summer mooring, I got that speed at that rpm while towing an inflatable dinghy in the worst possible location. I guess their estimate was pretty good. I delivered to a regatta last weekend (25 nm each way) - the new prop gives me 6.6 to 6.7 knots at 3000 rpm in flat water with a 12 to 15 knot headwind. There is reserve for chop. Vibration is nil. This installation is the smoothest I have ever had on this boat - I highly recommend it to anyone who wants better performance than they are getting now.
