An idea that came to fruition, the Obrien Valhalla incorporates one of the most radical ideas in wakeboarding. Four aluminum removable Crook fins in each corner of the board are out of the way when you do not need them and when on edge they bite like no other! While the board is flat, the rocker allows the Crook fins to be out of the water giving it a loose feel. The Valhalla has a variable-bevelled edge which is soft in the mid section for a floaty feel when flat and a smooth ride in choppy conditions. The dual moulded fins have a refined profile for minimal lift and drag. The Valhalla has a progressive rocker for the consistency of a continuous rocker and the pop of a 3 stage rocker. Has a double concave hull making for softer landings, composite deck with added strength but still extremely light.
