We Say: First launched in October 2016, the Ri257 was designed to create some of the biggest wakeboarding wakes and wakesurfing waves on the market. For 2018, though, this big boy has gotten even better thanks to the introduction of Centurion's new Opti-V hull. Simply put, the wakes and waves aren't just the best Centurion has ever created, they are among the best available. What's more, by reducing resistance on the running surface, the new hull stays more balanced and improves fuel economy. Better for wakes and your wallet? We'll take it.
