Sea Ray 510 Sundancer Boats For Sale

The Sea Ray 510 Sundancer is a 51-foot diesel express cruiser built around a two-cabin layout, with model years including 2015 and a 2018 Signature edition that added upgraded interior materials closer to Sea Ray's L-Class yachts. It measures 50 feet 10 inches length overall with a 14-foot-8-inch beam, a 4-foot-1-inch draft, and weighs roughly 42,000 pounds. The semi-displacement hull carries a 19-degree deadrise at the transom for a stable ride in chop. Shoppers looking at a Sea Ray 510 Sundancer for sale will find a boat aimed at weekend cruising, entertaining, and longer coastal runs for up to two couples.

Power comes from twin Cummins QSC 8.3-liter diesels rated at 600 horsepower each, paired most often with Zeus pod drives, though some hulls were built with conventional V-drives. Top speed is about 30 knots with a comfortable cruise near 24 to 26 knots, and range runs roughly 250 to 300 miles depending on how hard you push it. The Zeus pods and Mercury SmartCraft joystick make docking and tight maneuvering straightforward, and the system includes Skyhook station-keeping and Precision autopilot with auto-heading. One well-maintained 2015 example fitted with 8.3 QSC engines showed around 1,200 hours and ran about 29 mph, getting on plane quickly with a bow that stayed low for good forward visibility.

The helm sits in the upper salon, which Sea Ray calls the sun room, under a large electrically actuated skylight that opens the glass roof into a convertible top. Twin Raymarine multifunction displays, a Mercury engine information screen, VHF radio, trim-tab controls, throttles, and the Zeus joystick are laid out at the console, with stereo head units from Fusion or Rockford Fosgate depending on the boat. The double-bolster helm seat rotates roughly 90 degrees on a stainless track to face the salon table. Audio and entertainment run through JL Audio speakers, a Bose system, satellite TV via a TracVision dome, and on some boats iPad-controlled TV and stereo zones.

The cockpit seats eight to ten around a teak table that rotates and reconfigures, with an electric grill, a heat shield, an ice maker, and a retractable awning that extends over the seating on a button. The hydraulic swim platform is finished in teak, lowers into the water for swimming and tender launching, and includes an integrated boarding ladder plus three storage compartments holding the shore-power cable, freshwater hookup, and platform controls. Diesel fills sit on both sides of the transom. Forward, the bow carries adjustable reclining sun pads, a windlass with foot controls, and dual-access anchor lockers, reached by stairs on the starboard side.

Below, the galley to port has a two-burner electric cooktop, a microwave convection oven, and a refrigerator-freezer, with a lower salon sofa that converts to a double berth. The full-beam midship master offers a walk-around queen, hull windows, hanging lockers, a washer-dryer combo, and an ensuite with separate shower stall and an outside sink vanity. The forward VIP cabin has a double island berth, a hatch above, a cedar-lined closet, and an ensuite that doubles as the day head. The curved side windows read as continuous glass from outside but keep the hull strong, and the engine room earns praise for easy access to both engines and the Cummins generator.
