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.
Back in the water in Grenada - with new main and #2 and cockpit canvas (Santa came early). Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
