What about old MacGregor Ventures? 17, 21? Think they even made a 19 and a 22 at various times. I have a 17 - I've beached it. The swing keel does hang below the hull, but it's an 800 lb. boat. Jump off the bow and shove it off the shore.... (actually just moving yourself to the bow will usually get it un-stuck) There's a youtube video of me out on the Potomac on a windy day. Advertised to sleep 4. 2 + gear wouldn't be a problem. There is no separate potty area, unless you count the entire cabin. I think they look better than a Potter and they're certainly cheap. There's no tabernacle but I'm tall but scrawny and I rig and launch it myself in 20 mins. (only 3 stays, no spreaders) It tows great behind a 6 cylinder RWD unibody station wagon. Just something to consider.
Keep the expenses low and the good times high.
