AIRE Tributary Thirteen HD Self-Bailing Raft - The Tributary Thirteen HD Self-Bailing Raft by AIRE with its diminishing tube design, punches through waves and opens up more bow and stern cargo room. Now with a sporty new look and beefier 42 oz./2000 denier PVC material, it is great for adventure adrenaline or family fun. 7-8 paddlers can have a lot of fun, the two thwarts install with cam straps anywhere along the inside of the boat, or you can leave the thwarts out and install a rowing frame (sold separately). The welded PVC outer shell seams and the internal urethane bladders are the foundation of this highly durable self-bailing raft, and the lace-in floor bails water quickly for a safe ride. Four main tube air chambers provide a safety margin in case of an accident, and zippered tubes allow for easy access to the bladders in case repairs are needed. 10 D-rings offer plenty of room for gear tie-down, and four handles make for easy carrying. Sporty, fun, affordable and tough is what defines the Tributary line. They are built to withstand the rigors of regular river use. The AIRE Tributary Thirteen HD Self-Bailing Raft is sized and priced just right for whitewater fun with a paddle team.
