Designed as a smaller boat that can deliver a big wave at a more budget-friendly price, the Supreme S21 performed admirably during our day on the lake testing and riding behind it. In fact, we enlisted the assistance of the pros at sister publication Wakeboarding magazine to assess the wake, wave and rideability this boat delivers.
Our pro riders noted that the S21’s wave wouldn’t blow boaters away with how big it is, but they came off the water impressed with how capable it is for a variety of riding styles. At just under 21 feet length overall, the Supreme S21 might not be thought of as a boat that can make a solid wave, especially when compared to larger 24- or 25-foot boats, but we proved it defies the odds. The biggest thing we noticed when testing the S21 was that the pocket in the wave manifested itself farther back from the transom than the wave of many other boats of similar size. That characteristic makes it great for beginners, who often struggle controlling their speed and can become psyched out for fear of running into the back of the boat. On the other hand, the pocket of the S21’s wave proved big enough to allow advanced riders to build up speed for doing tricks or airs. Beginners to more-advanced riders will love the mellow, consistent shape and the sizable pocket of the wave this boat produces. Ya gotta love win-win scenarios.
We were also impressed with the running capability of the S21. Rushing to top speed proved no problem for this boat, and the 409 horses under its hatch creased the surface of the lake at 39.7 mph. From a standstill, it hit 20 mph in just 5.2 seconds, and it posted better than 3 mpg economy at 24 mph.
Supreme debuted the QuickFill ballast system, a 750-pound-capacity ballast tooled into the hull, aboard the S21. It fills up super-quick. An optional plug-and-play ballast provides even more wave-making.
If you don’t need the size of a bigger boat but want something that can easily provide serious wakesurf fun for you and your friends (while not breaking the bank), the Supreme S21 could be speaking your language.
High Points
* Built-in ballast system can quickly add 750 pounds of water weight to your surf experience thanks to the optional QuickFill system.
* Supreme’s SeeTouch Dash proved a simple, easy-to-use touchscreen that makes navigating the boat’s systems a breeze.
* Spradling matte vinyl used in the S21 is comfortable (the new camel color looks sharp!) and up to the rigorous demands placed by sandy feet, boards, spilled beverages and more.
