New features include the Maximus Tower, Centurion Downfire audio system with LEDs, flip-up stadium seating and so much more! The now standard RAMFILL ballast system provides you with the largest capacity tanks with the quickest filling system possible. No gimmicky surf-system, this is pure displacement and the SV233 is one of the most versatile wake boats with clean, professional wakes coupled with a World Wake Surfing Championship wave on both sides of the boat.
