High Performance
  • Swell 3.0 Surf System: This revamped system creates tall waves with long pockets and optimal push that’s consistent on both sides. Perfect for riders who like to transfer from side to side.
  • Supra Mega Velocity Sub-Floor Ballast System: Our new Mega Velocity Ballast System has capacities of up to 3,500 pounds, six pumps to reduce fill times and produces pro-level wakes and waves.
  • Raptor by Indmar 400: The Raptor series is based off a proven workhorse, the Built Ford Tough® 6.2L 16-Valve V8 engine that was designed, engineered, built and torture-tested by Ford®. The Raptor is the same state-of-the-art engine that powers the F-150 SVT Raptor and F-Series Super Duty Trucks that boast best-in-class gas horsepower, torque and max towing ratings. The 6.2L Raptor Series by Indmar® is the result of purpose driven engineering designed to provide more torque where you need it allowing faster acceleration, less time to plane, reduced wear-and-tear and better fuel economy.
  • Supra Competition Hull: The Supra® Competition hull was a benchmark design of Supra that took the performance of our boats to the next level. This innovation is alive and well across every boat in the 2018 line, resulting in massive wakes, stable point and shoot handling and a superior ride in rough water.
Precision Engineered
  • Patented Supra Autowake 2 System With Predictive State: In addition to automatically adjusting ballast for a precisely-shaped wake and wave, our second generation of AutoWake® features our groundbreaking predictive state technology. This all-new innovation senses and fills the ballast to predicted levels to provide a precise wave.
  • Supra Vision Touch System With Amplitude Display: Easily navigate through ballast and surf settings, GPS, stereo controls and more in full color. The VISION Touch™ System makes the SL as fun to drive as it is to ride behind. What’s more, the new amplitude display shows you how displacement of your boat in the water effects wake and wave size and shape.
  • Triple-Up Convertible Port Lounge Cushion: A perfect example of Supra® precision engineering, the convertible port lounge cushion lies flat for traditional wraparound seating or converts to a convenient backrest to take in the action behind the boat.
  • Easy Access Transom Surf Storage: The Supra® SL features an easy to access Transom Surf Storage locker to keep your boards safe and secure. With room for up to two boards and easy access from the swim platform our Surf Storage is one of those features you'll wonder how you ever lived without.

  • Bold Design & Styling: New for 2018, the Supra® SL features bold, muscular lines and a striking design sure to turn almost as many heads as the tricks pulled behind it.
Refined Interior
  • Mission Control Helm: The main focal point of the Supra® Mission Control helm is, of course, the billet accented full color screen of the VISION Touch™ System. Billet toggles and black-on-white soft keys accentuate the touch screen for more traditional pilots, while new audio components make fine tuning the sound as easy as pushing a button.
  • Led Interior Accent Lighting: Supra® lighted interiors light up the night whatever the mood. Inspiring LED floor and panel lighting casts a glow for that midnight cruise, or engage the integrated LED Halos in the JL Audio® Canisters, and turn up the soundtrack and the fun while the sun goes down.
