2018 Sea Ray Sundancer 510 Boat in Huntington, NY 11743 US

2018 Sea Ray Sundancer 510 Signature

The Sea Ray 510 Sundancer Signature Edition is already a rare offering. Finding one that has been maintained, upgraded, and cared for to this level makes this particular boat considerably more difficult to replicate.

This 2018 510 Signature has benefited from an exceptionally diligent owner who has approached the boat with the mindset of maintaining and improving it rather than simply using it. The level of care is evident throughout the vessel, from its mechanical service history and preventative maintenance program to the thoughtful custom details found in areas most owners would never address.

Originally a freshwater boat, she remained in freshwater service until being relocated to salt water in 2021. Since that time, the vessel has continued to receive attentive maintenance, with service performed in accordance with the Cummins recommended maintenance schedule. Aftercooler service was completed in 2023, and fuel conditioner has been used consistently from day one in both the main engines and generator.

The attention to detail extends well beyond routine service. When the current owner purchased the boat, the bottom was professionally sandblasted and refinished rather than simply recoated. The vessel has also been ceramic coated as part of an ongoing cosmetic maintenance program.

Even the machinery spaces reflect the same level of ownership. Custom storage trays have been fabricated within the bilge to neatly organize spare equipment and necessary onboard gear, an uncommon detail that speaks to how deliberately this boat has been maintained and operated.

Powered by twin Cummins QSC 600 diesel engines with approximately 635 hours, the 510 offers an excellent combination of performance, range, maneuverability, and interior volume. Joystick docking, pod propulsion, and a well-designed helm make the boat equally comfortable underway or around the dock.

An additional distinguishing feature is the aftermarket Brunswick Premier Protection warranty, which is fully transferable and remains in effect through January 2028. Coverage includes the main engines, generator, electronics, bow and stern thrusters, and pod propulsion system.

The electronics and entertainment systems have also been significantly upgraded. A TracVision HD7 high-definition satellite television system is paired with DirecTV receivers and upgraded high-definition televisions throughout the boat. The Fusion audio system has been comprehensively upgraded, including a dedicated master suite audio zone and an enhanced main salon zone with added woofer speakers.

Navigation equipment includes Raymarine electronics, open array radar, joystick control, and an EPIRB.

Exterior amenities include a hydraulic swim platform, teak cockpit, cockpit air conditioning, grill, refrigerator, and the extensive entertaining and cruising features that make the 510 Sundancer such a versatile platform.

A ZAR Formenti ZF0 tender is currently carried on the hydraulic swim platform and may be available as part of a negotiated purchase. The tender measures approximately 9'10" in length with a 5'8" beam, offers seating for five, and is powered by a 40 HP Suzuki outboard. Equipment includes a Fusion stereo, swim ladder, battery switch, 12 volt outlet, and USB charging.

Tender is not included in the advertised asking price. Inclusion may be considered as part of an acceptable offer.

What separates this boat from a typical 510 Sundancer is not simply its option list. It is the cumulative result of unusually attentive ownership.
