The Tarzan Boat is built exclusively for fun. Not speed, not luxury, not cruising. If you happen to be on Lake Havasu during the madness I think you would do better rolling up in this then in a speedboat or yacht.
You can pick from three sizes and have options like water slides, trampolines, high dives, and swing outs. Sure you could just get a normal party barge but this one takes it to the next level. Heck, even Mitt Romney has one.
