Stay away from Walker Bay air floor in my opinion. We have had nothing but trouble with ours and the repair gurus have given up on fixing the air floor, as soon as you fix one hole another appears. We had friends with a very expensive WB RIB, with center console and 20 hp. Also major problems and the company support was terrible.
We put Petit inflatable on our boat and never again. When you bring it on deck and fold it you get black powder everywhere. If it all fell off at once it would have been better. Ours just get falling off, now for more than three years.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
