Something to think about - depending on often your guests sail, they may not feel comfortable on the leeward side of the boat when it begins to heel. I have a 24 footer that will easily fit 6 people, and I have carried 5, but it tended to sink the rear of the boat. Either way, but my point is, if you want to carry a lot of people and have everyone comfortable, get a catamaran. Then all seats are usable.
