The board that started O'Brien's Delta base revolution! The Natural's full profile and wide tips are ideally suited to the rider who prefers a slightly tail-heavy approach to the wake. The blended 3-stage rocker kicks the tail into the wake and generates vertical pop. The variable beveled edge and quad molded fins provide secure edging even when not using the optional center fin. One ride is all it takes. Natural 134: 52.8"x 16.85". For 90-170 lb. riders. Natural 139: 54.7" x 17.1". For 140-220 lb. riders. Natural 144: 56.7" x 17.35". For 170-250 lb. riders.
