1990 Jefferson 42 Viscount Sundeck

The 1990 Jefferson 42 Viscount Sundeck is a fiberglass motor yacht built on a modified solid V-hull with a notably wide beam and shallow keel that provide stability and directional control in varying sea conditions. She is powered by two 300 hp Cummins 6BTA diesel engines with recent complete top overhauls including new injector sets and cylinder heads, new cooling systems with water pumps, cleaned and powder-coated engine blocks, and vibration couplers. The port-side transmission is new; both engines run with new fuel lines, hoses, and belts. She cruises at 15 to 16 knots with a long-range capability popular among Great Loop cruisers.

The two-stateroom layout accommodates eight and features a full-beam master suite with new custom queen mattress. The galley and dinette sit forward of the main salon. Two full heads and ample stowage serve the accommodation spaces. New countertops, dinette cushions, and galley flooring installed in winter 2026; recent teak furniture and wall coverings throughout. An 8 kW Westerbeke single-phase generator supplies power, backed by two Crusair 16,000 BTU air-conditioning units with recent compressor replacements.

The boat carries upper and lower helm stations, an aft deck hardtop with davit system, and generous outdoor living space. A new oversized swim platform and new captain's chair with fresh bridge cushions are installed. Recent navigation electronics include Simrad GPS, depth sounder, radar, and autopilot with remote and WiFi iPad capability; an Icom VHF radio and Fusion Bluetooth stereo complete the setup. A new bow thruster with remote control, new stainless steel port windows, recent windows on the bridge, and 60-gauge glass on the rear cockpit add to the specification.

Recent updates include new PSS dripless shaft seals, new non-skid on the foredeck, new galley flooring, and new exhaust hose. All port windows and hatches are new with no water intrusion. Spare alternator, starter, and an extra set of injectors are on hand.
