This freakin' thing is a blast. For like $350 you have a raft that flys!!!...When you get up in the air it is fun as a mofo, just like a flying dream. If and when you hit some turbulence all hell brakes loose, and if you cannot save it you skip across the water like a thrown rock...ouch, double-ouch...Once you get the hang it is exhilarating. We had everyone in the vicinity stopping their boats, and all they were doing, to applaud this floatation device that makes heros of mere mortals.
