The Swell Surf System utilizes high-speed rams to adjust 5/16-inch stainless steel blades laser cut and bent to control water turbulence off the rear of the boat's running surface. The specially designed trailing edge of these blades, or flaps as these types of elements are referred to in a fluid dynamics, create a vortex-effect behind the boat resulting in specific wave shapes. Different angels of deployment of the blades create custom effects in the water turbulence to swell-up Skim and Barrel waves. Swell blades benefit from a shot peen finish, a strengthening process commonly utilized in aeronautical construction, to increase the fatigue life of the piece. The Swell System is mounted and held together by a series of stainless steel through-bolts and stainless brackets for an extremely stable platform for wave making. The Swell Surf System is available on 2014 Supra SA and SC wake boat models only.
