The O'Brien Format Wakeboard is ready to take your riding to new levels this season! By using top-to-bottom full length wood stringers, they were able to both reduce the total volume of the board and decrease the overall weight of the fiberglass laminate, making a board that is up to 1.5 lbs lighter than our standard core. They have also redesigned the progressive rocker by lifting up the centerline of the board toward the tips, resulting in more vertical pop with no loss of speed to the wake. A double concave construction through the board's midsection softens impacts on landings. The base of the deck is finished off with 4 spine fins, the signature Delta Base for a faster ride, and a full length step-down rail to increase edge hold while carving.
