We have a C&C 37/40XL. We have a "J Prop" 18" three blade feathering propellor. Ours is the standard version, not the newer EP version. The J Prop is simply a wonderful propellor. The pitch is adjustable while fitted to the boat, a diver can easily (no tools required) make final fine tuning adjustment for you if you don't already have the pitch perfect when you install it.
Beta Marine imports the J Prop (it is made in Italy) and supports it in North America: http://www.betamarinenc.com/j-prop/ Several vendors in Canada sell the J Prop, including: http://www.hollandmarine.com/J-PROP.html https://www.marineoutfitters.ca/index.cfm?category=10025% 7C10777%7C11683&product=44098098&code=J%20Prop%2063153U100 https://ca.binnacle.com/product_info.php?products_id=10220 If you have heard of "Maine Sail" (Compass Marine) here is his take on the J Prop: We also run a J-Prop and it has been one of the nicest props I have owned or run a boat with. Smooth as glass, great power, a bit faster under sail, and stops on a dime. You would need to pry this prop from my dead fingers but I could not get rid of the Flex-O-Fold fast enough.. On this same vessel we have had a Michigan three-blade, Campbell Sailor, Flex-O-Fold two blade, back to Campbell Sailor (when the FOF did not work out) and now the J-Prop which has been absolutely flawless. We suffered ZERO speed hit compared to the CS and the Michigan, can still hit max rated RPM, and we sail slightly faster in lighter winds than we did with the CS and Michigan. If anything our speed under power may have gone up by .1 - .2 knots but this is hard to quantify. The surface area of the J-Prop is likely leading to less "slip" that we had with the Campbell. A sizing or pitch issue on the J-Prop takes about 40 seconds to remedy, if you launched it for "set up" without the pitch adjustment locked down...... Again, we have had a ZERO performance hit with our J-Prop and I am very, very, very picky on this stuff. It has honestly been the finest prop we have had on this boat in terms of performance, sailing speed and smooth. Or boat was re-powered back in 2001 so we now have a Yanmar 47 Hp Turbo. Our J Prop has no problem delivering those hp. to the water. I highly recommend the J Prop.
