The other day I was reading a boating world magazine (in a lobby provided by the lobby) and came accrost an add for hot tubs for boaters I suppose they have a aired up tube around them to float them and they heat the water that comes from the body of water that they are in to 110 degrees and does the Hot tube thing it was really bad ass looked like one of those floating trampoleens only with a hot tub in it instead!! I can't remember who made them or where to find them though! Has anyone herd of or seen these Hot tubs?
