There really isn't much room at all in the cabin of the 750. I did the RTI on one last year and you could probably sleep 2 people in it I guess but you wouldn'y be "hanging out" down there at all.
Tim, is the 28r going to have enough cabin space for all of you? I think 2 adults would be ok but 2 adults plus 2 teenagers would be cramped. There are always the tramps on either side if it doesn't rain and you coat yourself with Off. I went through the same issue thinking about which corsair to get. It is mainly because the wife wants a more "family friendly" boat than a beachcat and life is clearly too short to sail/race monohulls! Although there aren't many racing for the most part (but there are more 31s racing at nats than 24s) we have decided the 31 would be best for the mixture of cruising/racing. Probably 80% crusing overall. Looking at getting one within a year or so. Now how to fit the blade on the side tramp... <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
