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.

If you want to get more info on this, their web site is www.varipropusa.com, and they can be e-mailed at varipropusa@rivnet.net.
