Sleek styling, a large comfortable cockpit, and a luxurious interior that sleeps plenty are just the right formula for endless fun in the new 420 Sundancer. A wealth of instrumentation and information is at the captain's fingertips, and twin Cummins 8.3L 6CTA inboards will get you to most any destination with ease, with a Bow Thruster for easy handling around the dock. The thousand-hour service just performed, all engine hoses replaced, and new seawater pump impellers on the main engines and the generator. Both heat exchangers were removed and rebuilt. Both AC units were replaced, and the AC pump was upgraded to a larger size. The beautiful yet efficient galley includes a host of conveniences that make each day on-the-water excursion thoroughly enjoyable. All three refrigerators were replaced with new ones. The owner is moving up, don't miss this one! It has been maintained with an open checkbook by a knowledgeable owner. The boat has gone through many upgrades over the past few years, including changing over all lighting to LED.. Also included is the Freedom lift on the stern for a hard-bottom RIB. The Cummins Engines are all up to date on service. New props were installed in 2024. New Starlink System installed. See recent upgrades in listing done in the 2024 and 2025 seasons.
The Hard Bottom RIB is not included in the sale price of the boat!
Yet another Sea Ray sales success story, the 420 Sundancer (called the 44 Sundancer in 2006–08) set the gold standard for express yacht styling and luxury during her production years. Indeed, her muscular lines compared well with the best Mediterranean sportcruisers of her era, and a large cockpit and spacious interior made many of her European counterparts seem small in comparison. Built on a deep-V hull with prop pockets and a relatively wide 14-foot beam, the luxurious two-stateroom, two-head floor-plan of the 420 Sundancer is an impressive blend of high-gloss cherry joinery, Ultra-leather seating, and designer fabrics. Privacy doors (not curtains) separate both staterooms from the salon, and the Sundancer’s full-service galley includes an under-counter refrigerator/freezer in addition to Corian counters and hardwood flooring. Topside, a flip-up bolster seat is standard at the helm, and the entire cockpit sole can be raised at the push of a button for engine access. Note the extended swim platform, split forward head, and underwater exhaust system.
