Gra Boat | 31' Sea Ray 2018

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 wetbar make relaxation and onboard entertaining a given. Underway, the delight of good company merges with the thrill of precision performance, as the SLX's available twin MerCruiser engines and innovative Quiet Ride hull featuring Tuned Transom combine forces beautifully.
