1989 Jefferson 46 Sundeck
Powered by twin 3208 Caterpillar 325 Hp with only 2400 hours and a Westerbeke Generator with 2600 hours.
This Tri-cabin, dual head, Galley down has everything you need for coastal cruising or liveaboard.
Turnkey, extensively upgraded, and truly ready to cruise now, this 1989 Jefferson 46 Sundeck offers an exceptional opportunity for couples, liveaboards, and Chesapeake cruisers seeking comfort, space, and peace of mind.
M/Y Luthien is a highly desirable tri-cabin, dual-head sundeck motor yacht that lives more like a floating waterfront condo than a traditional cruiser. With a private aft master stateroom, separate guest cabin forward, two heads, a bright open salon, and a spacious sundeck for entertaining, she is ideally suited for Potomac and Chesapeake cruising, extended stays aboard, or full-time liveaboard living.
Between 2022 and 2025, Luthien benefited from nearly $80,000 in professionally documented upgrades and system renewals, addressing all major mechanical, electrical, plumbing, HVAC, and safety systems. Most notably, she is equipped with a new Sleipner SE130/250TC bow thruster system with dual helm controls, dedicated AGM battery, charger, and tunnel installation—dramatically simplifying docking and singlehanded operation.
Additional major investments include a comprehensive DC electrical backbone redesign and rewiring, replacement of shore power outlets and breakers, new terminal strips and cabling, new engine-room batteries and charging systems, generator rebuild and fuel system work, replacement of cracked exhaust hoses and clamps, fabrication and installation of new fuel supply hoses, raw-water system flushing and hose replacement, HVAC pump and electrical junction box replacement, bilge and seawater hose upgrades, and a full haul, block, and relaunch.
Luthien has been lovingly and expertly maintained by a retired U.S. Navy Captain with command experience, bringing a disciplined, no-compromise approach to safety, reliability, and system integrity. All work was performed by certified marine service providers and is fully documented. Complete maintenance records, invoices, and documentation are available for review.
If you are seeking a spacious, comfortable, and truly turnkey cruiser—without inheriting deferred maintenance or surprise projects—Luthien is ready to cruise today.
Between 2022 and 2025, M/Y Luthien underwent extensive, professionally documented repairs and system upgrades conducted by certified marine service providers including Potomac Marine, First Mate Marine, Kompletely Kustom Marine, Mad Jack’s Marine, Florida Bow Thrusters, and others.
