2020 Supra SL450 w/6.2L Raptor 450

Huge wakes and surf performance that leaves an impression—that’s what the 2020 Supra SL delivers, and then some. Throw massive waves and huge sessions behind this leading-edge performance towboat.

The smartest towboat on the water is also the hardest working. When it comes to delivering dense and solid wakes and waves, Supra is second to none. Our Swell Surf 3.0, Supra Launch System and the Supra Smart Plate along with 3500lbs of subfloor ballast all work together to throw the best riding wakes and waves in the industry.
