The Supra Boats @Supra_Boats Ride System (SRS) integrates wake performance features to enhance your riding. It all starts with the sturdy, easy-to-fold S-Bend or Pro Edge tower on the SA, which comes standard with swivel board racks, four rotating tower speakers, a bimini top and more. Supra's expandable Flex ballast or the SA's Liquid Lead setup and wake-shaping SmartPlate let you create ideal wakes for every level of rider. The Supra SmartPlate commands the flow of water moving past the hull and allows you to adjust the shape of the wake at the dash. The integrated Zero Off speed control and the unaffected wakes under the PURE Surf swim step deliver perfect pulls time after time. Harness all this powerful performance with the tap of your finger on customizable rider profiles stored in the all-new VISION Touch system. SRS is standard on the new SA350, SA450 and 550 as well as the 21V, 22V and 242. A 2013 Supra is all you need to shred!
