S21 Overview

We’ve all got priorities. By day you’re a hard-working professional. By weekend, an aspiring champion surfer. There’s no reason you can’t live the dream with the extraordinary S21. Designed with the professional in mind, it’s priced for the weekend warrior. The S21 first introduced Supreme’s QuickFill ballast system, which is a 750-pound capacity ballast tooled into the hull that fills with water in two minutes. In other words, it’s ready when you are to chase those goals. Optional Plug and Play ballast in the back is available to elevate your wake riding. It has room for 12, with safety and spacious seating prioritized.
