Designed with Parks Bonifay's superior knowledge of hydrodynamics, the Ronix Parks ATR wakeboard features a less-is-more rockerline and a supersized sweet spot with the most amount of surface area in a high-end board. The result is an easy-riding board that still provides a hard edge. Leave the wake with less work and more forward momentum. Its glide speed is similar to that of the One board, but it has a tighter overall feel transitioning and when edging. Center variable edge, plus a sharper rail and soft bevel create a controlled accelerated edge transfer with a forgiving bottom design. Thin profile reduces swing weight. ATR construction features durable, nonstick, sintered base that maintains glide speed, parallel carbon fiber weave to provide a more rigid layup than traditional fiberglass, ultra stiff core, and Krypto cable to strengthen the sidewalls.
