Its deep hull, high ballast capacity, and Indmar Raptor power deliver outstanding wave performance while maintaining the reliability and craftsmanship that define every MB Sports boat.
The MB Sports B52 23 Alpha represents the most advanced generation in MB’s long-running B52 23 lineup. First introduced in the early 2000s, the B52 23 series became known for its deep hull, large interior, and balanced performance across wake and surf disciplines. When MB launched the Alpha series in the early 2020s, the company redesigned the 23-foot model from the ground up to meet the needs of modern surf riders while maintaining its reputation for build quality and performance.
The Alpha hull brought major improvements to the B52 23 platform. It was engineered with a surf-first focus, featuring new running surfaces that create long, powerful, and well-shaped surf waves. Compared to the older B52 23 Classic, the Alpha has more freeboard, deeper seating, and greater ballast capacity. These changes make it one of the most capable surf boats in its size class. The added depth also provides a drier, more comfortable ride in rougher water, while preserving the responsive handling MB Sports boats are known for.
Powering the B52 23 Alpha is the Indmar Raptor engine line, most commonly the Raptor 400 or Raptor 440. These engines are based on Ford’s proven 6.2 liter platform and provide strong torque for quick planing and consistent pulling power even when fully weighted. MB pairs these engines with a direct drive V-drive configuration to deliver efficient, smooth power delivery and excellent reliability.
One of the most notable advancements in the Alpha generation is the ballast system. The B52 23 Alpha uses MB’s fast-fill ballast system that floods through gated valves, eliminating the need for pumps. This design allows the boat to take on thousands of pounds of ballast in just a few minutes. The system works in tandem with MB’s Surf System, which adjusts the flow of water around the hull to shape the wave on either side at the touch of a button. These systems provide an easy and precise way to switch surf sides or fine-tune the wave profile.
Inside, the Alpha design introduces a completely new interior layout with modern seating, expanded storage, and improved ergonomics. Materials and fit are finished by hand at MB’s facility in Merced, California, continuing the brand’s tradition of craftsmanship. The helm features a touchscreen interface that integrates surf control, ballast, lighting, and system monitoring in one place. Every detail of the B52 23 Alpha is built around user comfort, ease of use, and lasting quality.
As the flagship surf boat in MB’s current lineup, the B52 23 Alpha blends luxury and performance without losing the straightforward, handcrafted feel that MB owners appreciate. It remains one of the best options in the 23-foot segment for riders who value a powerful surf wave, simple operation, and proven reliability.
