Built by Nautique in 2023, the S21 Super Air is a 6.4-meter motor yacht that combines compact, sporty design with impressive watersports capability. This vessel delivers the quality, comfort, and craftsmanship Nautique is known for, offering an easy-to-handle package suited for both dedicated watersports enthusiasts and families seeking versatile recreational boating.
The S21 Super Air is equipped with a PCM Direct Injection V8 engine (128 hours) delivering strong torque and responsive performance. Key features include the Nautique Surf System (NSS) for customizable surf waves, an integrated ballast system for enhanced wakeboarding and wakesurfing, and Nautique Configurable Running Surface (NCRS) to optimize wake shape. Zero Off GPS Speed Control ensures precise towing speeds, while the Flight Control Tower serves as a convenient tow point. The spacious wraparound cockpit seating, open bow seating, generous storage, large swim platform, and Bimini top create a comfortable social environment. Entertainment is handled by a premium JL Audio system, with intuitive touchscreen controls for surf, ballast, speed, and boat functions at the helm.
This yacht suits buyers seeking an accessible watersports platform with excellent day-cruising versatility. The manageable 21-foot size makes it easy to operate while the integrated systems allow riders of varying skill levels to enjoy wakesurfing and wakeboarding. It is equally well-suited for casual family outings and social gatherings on the water.
