2025 MB B52 21 Alpha

The MB B52 21 Alpha is a wakeboard and wakesurf boat built on a 21-foot fiberglass hull with an 8.3-foot beam. Powered by an Indmar gasoline engine, it combines performance features typically found in larger models with a compact, manageable footprint. The design philosophy blends the styling and performance characteristics of MB's 23 Alpha with the comfort and safety priorities of the 25 Alpha.

The boat's raised freeboard enhances safety and keeps the cockpit drier in rougher conditions. The bow area provides spacious seating for passengers, while rear-facing transom seating lets spectators stay engaged with water sports participants. The hull and ballast system are engineered to produce customizable wakes and waves suitable for different rider abilities and skill levels.

Built for both wakeboarding and wakesurfing, the B52 21 Alpha handles leisure cruising as well as active water sports. Its design accommodates varied on-water preferences within a single boat.
