The Grand Canyon Cat. 27" tubes will give you more cargo capacity than you'll ever need. This cat has a continuous curve bow and stern. NRS "cats" are designed for extraordinary performance, agility and stability, whether transporting passengers and gear or sport boating. Precisely sized continuous-curve tubes enhance capacity, ride and maneuverability in all models. Extended wear patches allow for longer frames. As a safety measure, every new NRS Cataraft tube includes our three-chamber safety system. This system divides tubes into three separate chambers, providing flotation during emergency deflation. Repair kit included. Alternative colors may be available for fleet orders. Frames Sold Separately
