Flawless surf system 
 
The S21 was the first Supreme to introduce the Quickfill Ballast system which is a 1000lb hull-flooding ballast that fills the liner with water in under a minute. Optional Plug & Play ballast is available for professional wakeboarding and wake surfing. Inspired by the S226 the S21 is a wake surfing machine. The largest boat in its class with an excessive freeboard for performance, safety and spacious seating you’ll be shocked at how big this smaller boat is. 
Designed with the professional in mind, but priced for the weekend warrior, there is no other boat available that gives you a greater “bang for the buck”. The single highest performing wake boat available with standard features others reserve for options.
