The QuadConcave can be broken down into two parts:
1. Central Double Concave - Tracks laminar (water) flow through the centre of the board keeping you higher on the wave face, which allows you to generate more speed into your bottom turns.
2. Outer Venturi Channels - Draws the laminar flow from a wider entry point into a narrow exit through the tail. Based on Bernoulli’s principle, the laminar flow increases in speed as it progresses through the channel, giving you more drive.
The Quad Concave is precision shaped on our custom built AKU CNC shaping machine.
The AKU gives us the ability to design progressive channel and concave set-ups with incredible accuracy and consistency previously not possible by hand shaping.
Dave Winchester has brought his style, versatilty & all round talent to VS. Winny has created this model for the those after the top shelf version of his template in Parabolic core .
Dave has a legion of fans through his explosive & elegant wave riding. This model is a great choice if you dream of riding like Winny one day.
