The 6 Channel Concave creates an air pocket in the back half of the board. Breaking up surface tension & creating an air bubble resulting in more lift, less drag, increased speed while having better hold & rail control resulting in better manouvreability. This creates the ultimate board for speed & control.
1) Central Quad Concave's tracks laminar (water) flow through the centre of the board which keeps you higher up the wave face and enabling you to generate more board speed.
2) Outer Venturi channels draw laminar (water) flow from a wider entry point into a narrow exit through the tail based on bernoulli's principle, the laminar flow increases speed as it progresses through the channel, giving you substantially more speed, torque and drive. By combining technology with science, NMD & VS bring you the world's fastest bodyboard.
