Sea Ray got it right with the 510 Sundancer, a world-class sport cruiser designed for cruising and entertaining in unsurpassed luxury. With distinctive hull windows and an enclosed salon, the 510 is a big styling step forward from earlier Sea Ray express yachts with their open main decks and fiberglass arches. The Sundancer’s oversized salon windows, big windshield, and large sunroof flood the main deck living area with tons of natural lighting. Sliding glass doors open to provide a nearly level entry into the cockpit. With the galley down, the below decks layout of the 510 features a full-beam amidships master stateroom with walk-in closet system and private head and shower. The forward VIP stateroom has an en suite head as well, but some may find the centerline queen bed a little short for taller adults. The cockpit has a dining table with U-shaped seating to port, electric grill to starboard, and an engine room service hatch in the sole. Overhead, a power sunshade deploys from the hardtop to shade most of the cockpit. A hydraulic swim platform is standard. Cummins QSB8.3 600hp V-drive diesels cruise at 22–24 knots (high 20s top). Zeus-Cummins pod drives were optional.
