MyNautique ™
Integration

Incorporated into the Super Air Nautique G21, Nautique is proud to offer our integrated connectivity platform called MyNautique. With the ability to remotely view your G21’s fuel level, location, battery voltage and other important information, MyNautique allows you to virtually connect to your boat from your phone or computer.

Surf Pipe

Standard on the Super Air Nautique G21 is our Nautique Surf Pipe. This takes the steam and emissions from the engine down into the prop stream to bubble up behind the surfer, so you always have a great experience while you ride.

Nautique Configurable
Running Surface®

The G21 has incredible performance characteristics thanks to the Nautique Configurable Running Surface (NCRS). As an extension of the hull, the NCRS deploys and stows automatically based on user-setting conditions and allows the G21 to perform flawlessly at any speed and for any activity. The NCRS allows the wake and wave shape to be customizable, aids in getting up on plane, and automatically optimizes the running attitude of the boat so it's ideal for the situation, always providing the driver with great visibility.

Nautique Integrated Steering Assist

Nautique Integrated Steering Assist

The Integrated Steering Assist option provides exceptional maneuverability for your G21. With a thruster mounted at the stern, this option is perfect if you are docking in tight quarters, want to reverse in a straight line or are simply looking for more control on the open lake. Steering Assist allows you to quickly move the transom of the boat left or right, and significantly improves the overall driving experience.

Garmin® Watch Integration

Garmin® Watch Integration

Utilize the Nautique app for Garmin watches to remotely control the Surf Select 3.0 equipped G21 while you surf or wakeboard. Change your boat’s speed, music volume, NCRS, and NSS settings, quickly use ballast shift or change the wave side and transfer on the fly. This app works with a wide array of Garmin watches.

Nautique Surf System®

Nautique Surf System®

The Super Air Nautique G21 incorporates the Nautique Surf System (NSS) with WAVEPLATE® technology. Integrated right into the hull, the WAVEPLATE on the G21 is designed to work in concert with the hull to provide the best, most-configurable surf waves you could desire. The WAVEPLATE extends outward and down from the transom to redirect the flow of water forming the perfect, customizable wave on either side of the G21. Since the WAVEPLATE extends out on either side of the hull, it allows surfers to switch which side of the boat they’re surfing instantly and without the need to change up ballast or shift people in the boat. With multiple settings, the NSS also permits you to adjust the shape of your wave while you surf.
