The pro model Format Wakeboard started the wood revolution with O'Brien's Fusion Core. Top to bottom full-length wood stringers allow a superior wakeboard construction. Reduced overall volume and decreased weight mean the Format is easy to control when riding. The progressive rocker has been reinvented with a centerline that lifts toward the tips, resulting in more vertical pop with no loss of speed to the wake. The Format wakeboard has a subtle double concave through the clean midsection of the board that softens impact on landings. O'Brien's signature Delta base offers a faster ride and a full-length step-down rail to increase edge hold. Format 132: 52"L x 16.96"W. For 90-170 lb. riders. Format 137: 53.9"L x 17.11"W. For 140-220 lb. riders. Format 142: 55.9"L x 17.26"W. For 170-250 lb. riders.
