Have to agree that the Catalina 25 pop-top comes closest to fitting the wants you lay out in the first post. That said, keep in mind the trailering, rigging and launching a boat of this size is a major operation. OK for a week or two vacation, but you won't want to do it every time you want to go sailing.
Following up along these lines; I just saw sitting in the yard a Catalina Capri 22. Maybe not as much elbow room, but a whole lot easier to trailer, rig, launch, and haul.
What a sweet looking little boat. Looks to have nice lines, underbody, and wing keel. She should sail resonably well I suspect.
Head room would be an issue, but for weekend camping style, I would.

If a man is to be obsessed by something, I suppose a boat is as good as anything, perhaps a bit better than most - E.B. White
