This locally owned Supreme S21 is a great find with only 131 hours of use! It’s been well cared for and has all the right features like a quick fill ballast system, upgraded stereo, upgraded rear ballasts, upgraded trailer, and with its extreme pickle-fork design there’s room for you and 11 friends!

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 the optional Plug & Play ballast has been added and is excellent for professional wakeboarding and wake surfing. Inspired by the S226 the S21 is a wake surfing machine. The largest boat in its class with is excessive freeboard for performance, safety and spacious seating. You’ll be shocked at how big and capable this 21’ boat is.
