Hi Jeff,
I have the Sea Eagle Foldcat the two person frameless pontoon offered by Sea Eagle. It's bigger than the single person frameless pontoon but I'll do a pros/cons list for you.
Pros:
-Fits in the back of my Mazda3 (trunk has a gap to the back seat that i push the boat through when I put the back seat down). For comparison, my boat's deflated dimensions are 56" x 21" x 10".
-Comfortable bass boat seats that swivel
-Great for float trips.
-Stable - we stand up to cast on it all the time. with the swivel seats it means we can cast in any direction at any time.
-Electric motor attaches easily.
-Very high floating with a shallow draft. I've taken friends >250 lbs out fishing on it.
-Indestructible material
Cons
-Not very maneuverable, for a couple reasons. First, it doesn't track well. Second, it doesn't move too briskly with the oars, although that might be different for the single person boat . It's great when you can use the trolling motor, but often times you are using the boat to float over shallow areas - note that this is the same problem that any boat would have. Personally, I don't have any problems with the rowing bc I used to row crew, but it takes my non-rower friends a while to get the hang of it. In contrast to HeaveToo, however, I find it to be much dryer than my kayak because your never tipping the oars above your head (the resulting drip gets on your everything).
-Takes up more space than my inflatable kayak.
So as you can tell I have both the inflatable pontoon and kayak. I live in a condo too, but my fiancee won't let me keep the FoldCat in our place. I was thinking of selling it, but I'm storing it at her parent's house now so the problem is solved. I don't know what your storage situation is but I used to keep it in a little storage locker when we lived separately and that was great. I have a lot of accessories for the boat, which I invested a lot of time and thought into getting the perfect setup so I was glad not to sell it. But all the accessories actually take up just as much room as the boat. (my accessories: a trolling motor, a
marine battery, an anchor, and 2 lifejackets).
Hope that helps.
