The Centurion Ri237 already boasts the best waves, wakes and ride. Still, our engineers have found a way to improve the Ri237 by developing a completely new running surface for the 2018 model. The new Opti-V hull creates exceptional balance with engineered triangular pads on the rear corners of the hull. The side-to-side balance creates a symmetrical wakeboard wake, but because there is less resistance on this running surface the 2018 Ri237 delivers superior handling and 50% better fuel economy.
