2025 MB B52-21 Alpha

The 2025 MB B52-21 Alpha is a 21-foot fiberglass ski and wake boat powered by a single 350-horsepower INDMAR gasoline engine. Designed to balance the performance and styling of MB's larger models with enhanced comfort and safety in a compact package, this boat features a distinctive rolling wave top rail that serves both aesthetic and functional purposes—providing visual distinction while remaining easy to reach over when docking or picking up riders.

The audio package comprises Exile Audio components, 8.8-inch cockpit speakers, and a 12-inch subwoofer with 1000-watt amplifier. Additional standard features include non-slip padded flooring with two-layer construction, non-slip padding under storage compartments, sound dampening, a pass-thru wind dam, an MB ice chest, and transom remote control.

The boat offers surf racks and is available with powdercoat options for customization. Interior amenities emphasize comfort and usability across the deck layout.
