1989 Jefferson 46 Sundeck

This 1989 Jefferson 46 Sundeck is a three-cabin, two-head motor yacht powered by twin Caterpillar 3208 diesel engines rated at 325 horsepower each. The Westerbeke diesel generator supports onboard systems. With a beam of just over 15 feet and solid fiberglass construction, the boat combines spacious interior volume with manageable proportions suitable for Chesapeake and Potomac cruising or extended liveaboard use.

The layout centers on a private aft master stateroom, a forward guest cabin, and a bright open salon that flows into a galley situated below deck. Two full heads serve the accommodations. Above, a generous sundeck provides outdoor entertaining and cruising space. The arrangement works well for couples, liveaboard situations, or those seeking comfortable extended-stay capability.

Between 2022 and 2025, the boat received comprehensive system overhauls across all major mechanical, electrical, and plumbing infrastructure. Work included a new Sleipner SE130/250TC bow thruster with dual helm controls and dedicated battery, rebuilding of the generator and fuel system, replacement of cracked exhaust hoses and cooling lines, installation of new fuel supply hoses, a complete electrical backbone redesign with fresh shore power outlets and battery charging systems, and replacement of bilge and seawater hoses. A full haul, block, and relaunch were also completed. Engine-room batteries, HVAC components, and the raw-water cooling systems received fresh attention. All work was carried out by certified marine service providers and is fully documented.
