2021 Supra SL 450

The Supra SL 450 is a premier watersports tow boat

With more options and features than ever before, the redesigned Supra SL is a premier watersports tow boat designed to provide all 17 riders on board, no matter their skill level, a fun day on the water. First off, Supra didn’t compromise in any way when it designed the wake and wave of the SL. Featuring 3,500 pounds of subfloor ballast, the riding surface can be completely programmed and customized, and is capable of everything from an easy-to-ride, beginner wake, all the way up to a pro-level wake where the sheer volume of water could power a small village.

Moving into the interior of the SL, we couldn’t find a single thing to complain about. Everything was purposely designed and meticulously crafted, from the Chill Tech Vinyl (preventing even black vinyl from getting hot in the sun) and the FxONE Power Tower that folds with the push of a button, to the in-floor storage compartments and the GatorStep nonskid flooring from the bow to the swim platform. Supra’s designers even removed reasons for anyone to ever have to get up out of their seat by keeping everything within reach, including an in-sole cooler, phone holders, cup holders and USB charging ports.

At the helm, the captain will find a feature-rich dash setup that is both ergonomic and user-friendly. Two of the three touchscreen displays in Supra’s Vision Control System put the controls at your fingertips without you having to scroll and search for basic operational information. Between Supra’s patented AutoWake system and its preprogrammed rider profiles, you can be confident that the wake and wave shapes will stay consistent for the rider, even if passengers change seats during their set. We also loved the all-new heated captain’s chair featuring power controls, integrated software, and heated back and seat cushions. And a must-have feature for 2021: the dual stern thrusters controlled by twisting the knob of the throttle. No matter your prior experience, it’s hard not to feel comfortable and confident sitting at the helm.
