Great for every age and ability, the S21 serves up the fun for everyone that comes along!


Nautique is proud to offer the MyNautique integrated connectivity platform aboard the 2024 S21. Standard on this model, MyNautique gives you the capability to remotely view your S21’s fuel level, location, battery voltage and other important information from your smart phone, tablet or computer.

Electric Steering

The S21 received an upgraded steering system for 2024, providing a better driving experience in this boat than ever before. It now incorporates an electric steering system, which reduces the effort needed at the wheel and provides a much more refined feel whether you’re pulling a rider or simply driving down the lake.

Nautique Surf System®

The Nautique Surf System (NSS) with WAVEPLATE® technology was designed to work in concert with the hull of the S21 to provide the best, most configurable waves that any surfer would desire. The WAVEPLATE extends outward and down from the transom to redirect the flow of water and forms the perfect scalable and customizable wave on either side of the S21. Since the WAVEPLATE extends out on either side of the hull, it allows surfers to switch which side of the boat their 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.

Garmin® Watch Integration

Garmin® Watch Integration

Remotely control the Surf Select 3.0 equipped S21 while you surf or wakeboard with the Nautique app for Garmin watches. While surfing, you can change your boat’s speed, music volume, wave 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.

Integrated Steering Assist

Nautique Steering Assist

A stern mounted thruster, the Nautique Steering Assist option provides exceptional maneuverability for your S21. This innovation 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. Steer Assist allows you to quickly move the transom of the boat to the left or right and significantly improves the overall driving experience.

Nautique Configurable Running Surface®

Nautique Configurable Running Surface®

The S21 has amazing 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-settings and allows the S21 to perform flawlessly at any speed and for any activity you're participating in. The NCRS allows the wake and wave shape to be customizable, aids in getting the S21 up on plane, and automatically optimizes the running attitude of the boat for ideal driver visibility.

S21 Engines


The Super Air Nautique S21 now comes standard equipped with the PCM® ZZ5 with direct-injection technology. If you’re looking for even more power, the S21 has three other engine options: the 6.2L PCM ZZ6 with direct-injection, the Yanmar 8LV Diesel engine that delivers 595 ft-lbs. of torque, or the brand-new PCM ZZ8R that provides 570 horsepower and 600 ft-lbs. of torque. The PCM ZR4 is an option on this model as well, which is our 6.0L naturally aspirated offering.
