Steve,
I never really put it in the water but it would seem to work pretty well for two people. It's fairly wide so should be stable. You were right on the space issue. I could put it together in the cockpit, but there had better not be anything else in there with you. It pretty much took the whole area. Launching it was fairly simple, slide it over the side, but put something over the gel coat to protect the finish.
Disassembly was the real show stopper. You have to haul the whole boat into the cockpit. I was hoping to disassemble some of it in the water (the seats and transom, but that wasn't going to work. After that, I came to the conclusion there was an easier way.
I don't have a photo album set up, but PM me your e-mail address and I will send you some pictures. Basically I took two antenna rail mount adapters, welded railing T's on them, ran a piece of 1 inch stainless railing through them for the front. It clears the roof by about 1.5 inches. On the rear, I took a similar piece of 1 inch stainless and using u-bolts attached it to the vertical on the rear of the radar arch. After some more experimenting, I will eventually weld the cross piece to the arch or spot weld the u-bolts. This rear railing makes a good place to hang a tarp to cover the back deck until I get a camper back that will work with kayaks on the rack.
