Boat lift for my Formula
 

I'm looking for a boat lift for my Formula 272, my boat's usually berthed in the marina but always in the water (salt) but i'd like to get it out of the water after i have used it but keep it moored in it's berth. I've been looking at an Airberth, someone in my Marina has one and it looks like it could be a solution. Has anyone experience of Airberth's??
