Introduced in 2000, the 510 Sundancer was impressive display of Sea Ray's world-class design and engineering skills. Unlike her narrow-beam European counterparts (Sunseeker, Cranchi, Pershing, etc.) with their slender interiors, the Sundancer's widebeam hull results in a surprisingly spacious interior positively loaded with luxury features. The two-stateroom layout is dominated by a vast main salon with high-gloss cherry joinery, deep pile carpeting, and a posh Ultraleather sofa with electrically operated slide-out bed. To port is a home-size galley with Corian counters, hideaway mini-bar and copious storage. Forward, the large master stateroom features an island double berth, vanity with sink, and private en-suite head. (Both heads have separate stall showers.) The cockpit, with its wraparound helm console, retractable sun pad and stylish hardtop, offers seating for a small crowd. Additional features include a central vacuum system, underwater exhausts, and anchor washdown. Twin 660hp V-drive Cats cruise the 510 Sundancer at 25 knots (about 30 knots top), and 770hp Cats cruise at 26 - 28 knots (low 30s top).
