The innovative Vault wakeboard from Ronix recognizes that your body is crossed up when riding toeside. Taking this into consideration, the design of the rocker and fin shape/placement allow the rider to point the board with maximum grip to the wake without requiring excessive attack angle. The toeside rail is thinned out to sit deeper in the water, creating additional grip from this sharp profile. The toeside fins are deeper, longer, and closer to the rail for a strong/stable edge hold. The design of the heelside was created for a rider facing the boat with a more natural position to point the board to the wake. The heelside rail starts off softer/fuller for a mellower transition, then blends to a more vertical sidewall with less resistance on the water. The heelside fins are shorter and further from the rail for a quicker release on spinning tricks. A wider profile creates a bigger sweet spot in any water condition. Includes 2 fiberglass 1.7" fins.
