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.
In South Africa doing lots of boat stuff. Departure north from Cape Town around December 15th. Arrival in the Caribbean around the beginning of February, after 5300 miles or so.
