Magnum Marine has nicknamed this model “Bestia,” the Italian word for beast. The Magnum 51, which launched September 2009, certainly lives up to its pet moniker. The 50-foot powerboat—the long-awaited follow-up to the Magnum 50, which the South Florida builder launched in 1993—boasts a handsome exterior with sleek topsides bearing flush anchor lockers, cleats, and other would-be protrusions. The cockpit area features ample seating for passengers, as well as a spacious sun pad aft. Below deck, a stand-up interior affords lavish living accommodations. Even with a carbon-fiber superstructure, the Magnum 51 still weighs a hefty 52,000 pounds, which helps provide comfort and stability while traveling at the high speeds afforded by the boat’s twin Caterpillar or MTU diesel engines.
