Performance & Wake-Shaping Innovation

Moomba SmartPlate™ & Flow Surf System: Zero passenger shifting required. The combination of Moomba's adjustable trim plate and automated surf tabs effortlessly cleans up and shapes a flawless, massive wave on either side of the boat at the touch of a button.
AutoWake® Technology: This patented system acts as your digital co-pilot. AutoWake continuously measures the boat’s pitch, roll, and water displacement, automatically adjusting the ballast levels in real-time to maintain a perfectly consistent wave shape, regardless of where your passengers are sitting.
Massive Integrated Ballast System: Features up to 3,700 lbs of factory-loaded ballast tucked neatly into sub-floor hard tanks and rear plug-and-play bags, giving you a heavy footprint for deep wave displacement.
Agile 21' 5" Hull Architecture: Designed with a deep-V entry that cuts through rough lake chop seamlessly while maintaining a tight turning radius for stress-free driving and simple docking maneuvers.

Interior & Driver Command Center

The Minimalist Helm Station: Built with the driver in mind, the dash features a crisp 7-inch touchscreen display housing all critical engine vitals, ballast controls, and custom rider presets. Navigating the lake has never been more intuitive.
Transformable Rear-Facing Seat: The sliding rear cockpit bench effortlessly transitions into a rear-facing observer station, ensuring your crew gets a front-row seat to watch the action happening behind the transom.
GatorStep® Non-Skid Flooring: High-durability, slip-resistant marine flooring flows seamlessly throughout the deck. It stays remarkably cool to the touch on hot summer days and makes post-lake cleanups a simple spray-and-go affair.
Aft Sun Pad with Walk-Through: A dedicated transom walk-through path protects your premium marine vinyl upholstery from premature wear when passengers move from the cabin to the rear swim platform.
