MB B52 21 ALPHA FEATURES
Features That Set the Standard
MB Surf System: The B52 21 features a high-performance switch-style surf system paired with a massive 3,000-pound ballast, allowing you to sculpt clean, powerful waves on either side of the boat instantly, despite its compact footprint.
Indmar Raptor Power: Equipped with the reliable Indmar Raptor 400 6.2L, this engine provides incredible low-end torque. It’s perfectly tuned to pop this nimble 21-foot hull on plane even when the ballast is maxed out and the crew is full.
Dual-Screen Command Center: The helm is designed for the modern captain, featuring dual high-resolution touchscreens and a digital "Surf Command" interface for seamless control of ballast, cruise speed, and wave shape.
Exile Audio Experience: The Exile Audio® premium sound package is tuned specifically for the B52's cockpit, featuring high-output tower speakers and zone-controlled subwoofers for a concert-quality experience that reaches well beyond the swim platform.
Signature B52 Styling: From the custom-stitched "Cool Touch" vinyl to the aggressive profile of the Mission Power Tower, the B52 21 combines luxury aesthetics with the rugged, handcrafted durability MB is known for.
Exterior Design: Where Bold Meets Refined
The MB B52 21 features an aggressive, hand-crafted exterior that balances head-turning style with heavy-duty utility in a compact, agile frame:
Aggressive 21-Foot Profile: The B52 21 maintains the sharp, faceted hull lines and signature wide spade bow of its larger siblings, delivering a powerful on-water presence and a spacious bow lounge rarely found in a boat this size.
Infinite Customization: From vibrant metal flake gelcoats to stealthy matte finishes, MB offers a nearly limitless palette of custom hull colors and powder-coated accents, allowing you to make your 21-footer a true one-of-a-kind masterpiece.
Functional Integration: Seamlessly integrated LED docking lights and heavy-duty GatorStep non-skid pads across the gunwales and swim platform ensure safe boarding and effortless low-light maneuvering.
Hand-Laid Durability: Unlike mass-produced hulls, the B52 21 is built with a traditional hand-laid fiberglass process, providing a solid, rattle-free ride and the "heavy water" feel that MB owners demand in a premium towboat.
Interior Luxury
Step inside the MB B52 21 and immerse yourself in a cabin designed for elite comfort and high-capacity hosting in a compact, social package:
Social-Centric Layout: Despite its agile 21-foot length, the B52 21 boasts a generous 100-inch beam and a wide spade bow, comfortably seating up to 14 passengers with a layout that maximizes every inch of floor space.
"Cool Touch" Premium Vinyl: Experience the pinnacle of comfort with hand-stitched, marine-grade upholstery featuring heat-reflective "Cool Touch" technology, ensuring your seats stay manageable and cool even during the peak of summer.
Adaptable Lounge Seating: The interior features versatile flip-up transition seating and a spacious sun pad, allowing your crew to easily pivot from forward-facing travel to a stadium-style view of the surf action behind the boat.
All-Season Comfort: Stay on the water longer with integrated cabin heaters and heated captain’s seating, specifically designed to extend your season through those crisp early morning sessions or late autumn runs.
Atmospheric RGB Lighting: Fully customizable RGB LED interior lighting runs throughout the cabin, allowing you to set the perfect mood—from a relaxed evening cruise to a high-energy sunset session.
Versatile Storage Solutions
Engineered for the active family, the MB B52 21 maximizes every inch of its nimble frame with smart, high-capacity storage designed to handle a full day's gear:
Deep-Hull Storage: Even in this compact 21-foot model, you'll find deep, cavernous compartments beneath the hinged seating that provide plenty of dry space for life jackets, ropes, and gear, keeping the cockpit organized and clutter-free.
Swivel Board Racks: The Mission Power Tower comes equipped with heavy-duty, swiveling board racks that securely hold your surfboards and wakeboards, offering easy access from inside the boat while protecting your equipment.
Integrated Chill Zones: Features a dedicated cooler space designed to keep your beverages icy and organized, ensuring the crew stays hydrated during the longest summer days without sacrificing footroom.
UNRIVALED POWER AND PRECISION
The MB B52 21 delivers world-class performance and a heavy-hitting ride for every adventure, packed into a highly maneuverable 21-foot frame:
Torque-Heavy Indmar Power: Equipped with the Indmar Raptor 400, the B52 21 provides smooth, aggressive acceleration and the reliable low-end torque needed to plane effortlessly, even when utilizing its full ballast capacity.
Performance-First Deep-V Hull: The signature MB deep-V hull is designed to slice through chop for a stable, comfortable ride while displacing a clean, pro-level wake that remains consistent and tall in all water conditions.
Precision Surf Interface: Using the "Surf Command" system, drivers can instantly toggle between high-speed cruising, fuel-efficient towing, or customized surf modes to perfectly match the rider’s skill level and wave preference.
Handcrafted Quality & West Coast Grit
Every inch of the MB B52 21 reflects MB Sports’ legendary commitment to precision and durability, delivering a premium experience in a versatile 21-foot package:
Artisan Hand-Stitched Upholstery: The interior features meticulously crafted marine-grade vinyl, hand-stitched by experts to withstand the elements while providing a luxury feel that remains durable for years of heavy use.
Over-Engineered Construction: Built using a traditional hand-laid fiberglass process and a solid stringer system, the B52 21 is engineered to provide a rattle-free, heavy-duty ride that mass-produced boats in this size class simply can't match.
Distinctive B52 Aesthetic: A bold blend of aggressive styling and refined elegance, the B52 21 features custom powder-coated hardware and timeless lines that command attention and maintain their value on any lake.
Dimensions
The MB B52 21 is engineered to provide the perfect balance of a high-capacity social platform and a high-performance towboat in a nimble, easy-to-manage package:
21-Foot Length: At 21 feet, this model offers a spacious interior footprint that maximizes passenger comfort and storage while being significantly easier to garage, dock, and trailer than larger alternatives.
100-Inch Beam: The ultra-wide 100-inch beam—the same width as the larger Alpha models—provides incredible lateral stability, a dry ride in rough water, and a massive cockpit layout that feels much larger than its 21-foot length suggests.
Deep-V Draft: Designed with a deep-V entry, the hull sits deep enough to displace massive amounts of water for surfing while maintaining a predictable, smooth plane for cruising.
Heavy-Duty Displacement: With a dry weight of 5,000 lbs, the B52 21 offers the heavy, solid construction necessary to plow through chop and create a dense, world-class wake that typically requires a much larger boat.
Next-Level Watersports Engineering
The MB B52 21 serves as the ultimate high-performance platform for every discipline on the water, proving that you don't need a 23-foot boat to get a pro-level experience:
Pro-Level Wakesurfing: Generate world-class, massive waves with the MB Surf System, offering a long transition and a clean face that satisfies both professional athletes and beginners, all powered by a 3,000-pound ballast optimized for the 21-foot hull.
Precision Wakeboarding: The deep-V hull and weighted displacement create a rock-solid, crisp wakeboard wake with plenty of pop for big air and predictable, smooth landings that the B52 series is legendary for.
Multi-Sport Versatility: While it’s a surf-first machine, the B52 21’s agile size and adjustable trim allow for family-friendly fun, providing stable wakes for tubing and recreational skiing.
One-Touch Rider Profiles: Using the digital "Surf Command" interface, you can save and instantly recall custom ballast and speed settings, ensuring every rider gets their perfect, personalized wake every time at the push of a button.
Why the B52 21 Stands Alone
The MB B52 21 stands out in a crowded market by prioritizing raw performance, handcrafted quality, and a user-focused experience in a versatile, compact frame:
Pure Performance Innovation: Unlike complicated, over-engineered systems, MB’s proprietary Quick Fill ballast and Surf Command interface provide instant, heavy-hitting waves without the wait, making the most of every minute on the water.
True "West Coast" Versatility: Built to handle everything from aggressive, pro-level surf sessions to high-capacity family cruises, the B52 21 transitions between sport and luxury effortlessly while remaining easy to maneuver in tight marinas.
Artisan Personalization: With a focus on semi-custom builds, MB allows for a level of aesthetic customization—including powder-coated towers and unique gelcoat patterns—that makes your 21-footer a distinct reflection of your personal style.
Purpose-Built Efficiency: By pairing the Indmar Raptor hull-specific tuning with a high-displacement 21-foot hull, this model optimizes fuel consumption while maintaining the massive torque required for heavy towing and rapid planing.
