Share the thrill

The SLX 310 demands everyone's full attention. And by everyone we mean not only the abundance of people who can lounge comfortably onboard, but also the passersby whose heads will turn at the iconic styling and elegant hull sculpting. An expansive cockpit social area, an aft-facing lounger that converts to a sunpad, and a standard wet bar make relaxation and entertaining a given. Underway, the delight of good company merges with the thrill of precision performance, powered by available twin MerCruiser engines and the innovative Quiet Ride hull.
