We just got back off our Lio Kai charter and were looking at ownership options on a new 42 as well. It looks like both the 40 and 42 are using the split (A-frame) mainsheeting system. The one dislike I've always had on the M4000 is this setup, and I'm sad to see the 42 uses it as well... though at least they add another dedicated winch. Running all lines including a split main on just two winches is nuts to me. The third winch would help for sure, but I'd still like to see this system go away, The 4500 is using a traveler. The *only* advantage to the casual cruiser that I can think of in a split main is that jibes are a bit safer (and the boom is still and quiet at night at anchor). Wondering what owners, who will have a lot more experience sailing these than my few weeks worth, think.
