I've had a West Marine inflatable (hypalon) which was made by Zodiac for 9 years now. It stays outside on a dock with no cover in the Northeast US. One of the tubes has had a slow leak that I haven't been able to find. I have bottom paint on it. It has held up reasonably well. I don't know if they've changed the design of the hard floor which is 5 plywood panels that fit together, but I hate this design. I dread having to put the floor in and take it out at the beginning and end of the season. A real PIA job.
We take the engine off and tow it on cruising weekends. Overall I'm satisfied, but will probably look at other options, so I will be reading this thread with interest.
