Dimensions: Length 16' 6", tube diameter 20", Self Bailing Floor. This boat is full of versatility. Created in the early 90's as a larger paddleboat for our eastern commercial outfitter market, the Tempest 1 SB's popularity has flowed into the extended trip western style of river running. Paddle the Tempest with four thwarts or drop the thwarts and load a cargo frame for a Main Salmon trip. The Tempest 1 features ten 2.5" D-rings, four removeable thwarts, a full 5-year warranty, Maravia's TOUGH Class VI base fabric and the best URETHANE coating on the market - over 40 times the abrasion resistance of PVC and over 15 times the abrasion resistance of Hypalon. We will discount the price if you wish less than four thwarts.
