The 2025 MB Sports B52 21 Alpha is a compact powerhouse that merges big-boat features into a 21-foot frame making it ideal for families, thrill-seekers, and serious wake surfers alike. It effortlessly blends performance, comfort, and style:

Perfect size, huge performance
At 21 ft, this boat packs in power and space typically found in larger models. Step aboard and you’ll feel like you’re on something much bigger thanks to roomy bow seating, built-in transom benches and a rolling wave‑rail that’s functional for boarding and docking 

Indmar Raptor 400 engine & plug‑and‑play ballast
Powered by a 400 hp Indmar Raptor V‑drive engine with plug‑and‑play ballast (900 lb port / 650 lb starboard), this boat generates strong, surf-ready waves with minimal adjustments

Surfers’ dream wave, every ride
MB’s deep-V hull and Switch Surf System produce consistent, perfectly shaped wakes—so you spend less time tweaking and more time shredding 

Premium interior & tech
Features include dual screens (5.5" + 7"), RGB cockpit lighting, Exile Audio with subwoofer, sound-dampening flooring, and a heated, powered captain’s chair. The craftsmanship and upholstery quality impress from the moment you step aboard 

Smart, stylish, and functional design
With a mission power tower, surf pipe exhaust, non-slip flooring, transom remote, wireless charging, and thoughtful details like glovebox and storage lighting, the Alpha 21 is as much about livability as it is about performance

Bottom line: The 2025 MB Sports B52 21 Alpha isn't just a scaled-down boat, it’s a fully featured wake-surf machine with big-boat capability in a nimble and stylish 21-foot package. Perfect if you want top-tier performance without the bulk.
