I recommend you go to YANMAR America Corporation
for best advice. C & C designed & built the boat, and would have gone to Yanmar to spec an engine and prop. Fixed props are the norm, folders the compromise to achieve race performance, there is always a trade off - performance under sail v performance under power.
Hopefully you can cut through at Yanmar to someone to get some good, down to earth advise on the BEST PROP FOR YOUR BOAT IN YOUR SITUATION. If you are only cruising you might also consider a 3 blade over a 2 blade.
BTW, our 32 has the offset shaft too. It is great for leaving dock on starboard side as it pulls to port in forward, and great for approaching dock on port side. We dock in a river with canal outflow that varies from 2 to 6 knots throughout the day. We swing a Flexfold geared folder - some minor improvements under sail (well, we finished second in each series this year handicaping against another C&C 32, CS27 & a J24 in main n jib fleet, and it wasn't entirely crew expertise, or was it?
), but there is noticable prop whip under power. There are some good SN threads discussing this too.
