I haven't sailed either boat mentioned, but like Matt have seen the Melges 24 up close in action. While it was faster than the J24s at the same (large) regatta, it was MUCH slower than the Melges 32, which blew me away with how fast a monohull could go (granted, it was blowing 18+ knots).

Having said all of that, I wouldn't trade my Hobie 16 for any of them. A trimaran, maybe... <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
