Magnum Marine is known for its speedboats—capable of traveling at 50-plus mph. In honor of its 45th anniversary this year, the company created the special-edition 51 Gold Label. It’s a 51-footer, painted gold, styled by famed yacht designer Luiz De Basto, along with Magnum Marine president Katrin Theodoli. The 51 Gold Label’s reported top speed is 70 mph; power comes from twin 1,600-hp MTU diesel engines. Given the dramatic styling and blistering speed, no wonder Magnum has nicknamed this boat “The Beast.” For quieter times at anchor, the interior of the 51 Gold Label features a queen berth, a head, and a galley.
