Face it, stowing a tube on small boats, ski boats and PWC's can be a hassle! We designed SURF with these watercraft in mind. Despite its small size, 54" x 43" (deflated size), SURF is big on performance. Sit on top or lie down, either way, you'll love the remarkably stable ride. Four deluxe handles with neoprene knuckle guards provide a great grip. SURF is equipped with a Boston valve for fast inflating and deflating, 2 boarding straps and a drain vent.
