2001 Sea Ray 510 Sundancer 800 CAT

Welcome aboard "Navion"—a truly exceptional example of the Sea Ray 510 Sundancer. She is one of only three ever built with the upgraded 800 HP Caterpillar 3406E engines, a rare and highly desirable enhancement over the standard 640 HP package. This powerful upgrade delivers noticeably improved performance, reliability, and overall cruising confidence.

Over the years, Navion has been meticulously cared for, always stored in heated winter facilities and consistently upgraded with thoughtful improvements to meet her owners’ high standards. Her condition reflects a level of pride and attention that is immediately apparent.

The 510 Sundancer is an impressively large 51-foot yacht, and Navion fully embodies that presence. Her high freeboard and deep-V hull provide not only a commanding profile but also a remarkably smooth, stable ride—even when conditions are less than ideal. Below deck, you’ll find a spacious, beautifully appointed interior, while above, the expansive aft deck offers an unbeatable setting for entertaining.

For the discerning Sea Ray enthusiast, "Navion" represents a rare opportunity to own a standout vessel that perfectly blends performance, luxury, and pedigree.
