Is the aft cockpit drier ?? prolly a bit in heavy weather. Given a choice i would take the cc everytime. You are not usually under heavy weather conditions and so, you can put up with some wet for a while.
The CC gives you a few extras tht have already been mentioned , but what they didn't mention is how it effects the layout below...I love an aft main cabin
Had a jeaneau 45 CCfor a few weeks and never had a problem ..loved every minute..sail one or two of each !
No better way to find out what suits you best ...but the very minor negs about the CC are far outweighed
