The Super Air Nautique G21 has an abundance of room for your friends and family and plenty of storage space as well. Nothing is sacrificed as it produces wakes and surf waves beyond comparison with any other boat in its size-class, and you still get the legendary G-Series performance along with the high quality you expect out of a Super Air Nautique. Hull The Super Air Nautique G21 hull design works in concert with the Nautique Configurable Running Surface (NCRS) to fine-tune the hull under any condition for every application along with 2,850 pounds of sub-floor internal ballast. Sharing the technology and ballast of the entire G-series line, the G21 leaves nothing to be desired in a twenty-one foot boat that maintains the ability to create the most progressive wake and wave in the industry. The Nautique Surf System is seamlessly integrated into the hull offering full wave customization with the ability to transfer to either side in seconds. Surf System The Nautique Surf System (NSS) with WAVEPLATE technology is integrated into the hull to engage on either side of the transom at surf speeds working seamlessly with the running surface to create a larger wave with each pound of ballast. Offering full adjustability, the WAVEPLATE extends outward and down from the transom to intercept and redirect the flow of water forming a wave that can be customized for every surfer. NSS allows surfers to switch sides instantly without the need to offload ballast or people and fine-tune the wave with variable settings that adjust steepness and shape by controlling exactly how much the WAVEPLATE is engaged. Sound Nautique and JL Audio seek to enhance your experience on the water with the ultimate sound system. For 2018, the Super Air Nautique G21 comes standard with the M-Series Elite package including 6 JL speakers and a 10” subwoofer powered by an 8-channel amplifier. If you’re looking to amp it up even more, upgrade to our M-Series Studio Elite package that includes an additional subwoofer with a monoblock amplifier and two in-dash tweeters.
