Shawn Watson's pro model has all the bells and whistle, as well as Watson's seal of approval. Features carbon X construction for increased torsional rigidity. The triple concave, aggressive 3-stage hull design generates a high trajectory pop off the wake, yet breaks the water for softer landings, all while maintaining speed and flow. Concave V-channels at the tips increase speed and lift and provide for strong edge hold. Watson 135: 53.2" x 16.8". For 90-170 lb. riders. Watson 139: 54.8" x 17.2". For 130-210 lb. riders.
