This 23 Foot Centurion Is Built for Serious Water Sports. The Nv233 offers two extra feet of space than the Nv213 and a Bold, Performance-Driven Profile. With Centurion's exclusive RAMFILL ballast system the Nv233 is a surf powerhouse built on our Opti-V Hull with Quick Surf Pro and a Silent Stinger Wake Plate for an epic, smooth, adjustable ride that is also inside-voice quiet. And with the Nv Series' new step-up transom step, it's easier than ever to get back in the boat to celebrate a new trick. The Nv233 leaves nothing out—except your next day on the water.
