Bring more friends along on your next whitewater rafting adventure by adding an additional thwart to your NRS 12' Revolution Raft. Adding another thwart provides spots for more paddlers and extra flotation for your raft. The NRS BAT (TM) (Batten Attachment Thwart system) lets you easlily add or remove thwarts to accommodate paddlers or a rowing frame (this thwart comes with two unbreakable battens and the thwart side patch, boat side patch not included) . Trouble-free Leafield (TM) C7 Valve guarantees simple, reliable inflation and deflation. Built with the same quality materials and workmanship as your NRS inflatable boat.
