Overview

Jefferson 42 Sundeck

This Jefferson 42 Sundeck is suited to Chesapeake Bay and Intracoastal Waterway cruising, Great Loop adventures, or life aboard at the dock. Her spacious salon, full-beam sundeck, two staterooms, and two heads provide comfortable living and entertaining space.

Hand-finished teak cabinetry and parquet floors give the interior a classic character. The galley-down layout includes a full-size refrigerator/freezer and a four-person dinette that converts to a double berth. The aft master stateroom features a queen-size berth, generous storage, and an ensuite head with a marble washbasin, gold-tone faucets, and a tub/shower. Forward, the guest cabin has bunk berths and access to a second head with a separate shower stall.

The enclosed sundeck provides sheltered access to the flybridge, where generous seating and good helm visibility complement the wide side decks and side door at the lower helm. Twin Cummins diesel engines power the vessel.

Design and Builder

Designed by naval architect Robert B. Harris, the Jefferson 42 Sundeck shares its hull with the Jefferson 42 Convertible. Its classic motor-yacht lines combine modern engineering principles with established construction methods and materials.

Leon Shaw founded Jefferson Yachts in 1982. The company initially imported and marketed trawlers and motor yachts built by Hershine Marine in Kaohsiung, Taiwan, beginning with the Jefferson 45 Motor Yacht. In 1994, Jefferson introduced center-console fishing boats built in Jeffersonville, Indiana, followed by motor yachts, sportfishing boats, and express cruisers ranging from 30 to 82 feet. The company declared bankruptcy in 2012.

Service Access

Four large salon-floor hatches provide access for major engine and machinery work. A door beneath the galley steps allows routine inspections without disrupting the salon. Opening side windows feature tinted safety glass and screens.

Flybridge

The fully enclosed flybridge offers protection from the weather and good visibility in all directions. Guest seating flanks the helm on port and starboard, with storage beneath the double helm seat and other seating areas.

Sundeck

The spacious sundeck is designed for relaxing and entertaining. Its enclosure provides shelter or opens to admit a breeze. A transom door leads to the ladder down to the swim platform, while an interior ladder provides sheltered access to the flybridge.

Double doors open into the salon. Beside them, a custom cabinet offers a large surface for use as a workbench, buffet, or serving area, with drawers and shelf storage below.

Forward Stateroom

Two starboard bunk berths, each 6 ft 5 in × 30 in; two added steps ease access to the upper bunk.
Two drawers and additional storage beneath the lower berth; a tall hanging locker aft of the bunks.
Port-side low locker with shelves and a large counter; dressing mirror beside the head entrance; fiddled shelves along the hull sides.
Headroom: 6 ft 7 in.
Two overhead LED lights, a reading light, three screened opening ports, and a screened overhead hatch.

Forward Head

Accessible from either the galley or forward stateroom, the forward head has a separate shower stall to the left of the entrance. The sink has storage beneath it and a medicine cabinet alongside. The aft-facing electric head is forward of the sink.

Two large mirrors, two overhead LED lights, and two screened opening ports brighten the space. Headroom is 6 ft 7 in.

Galley and Dinette

Four steps forward from the salon lead to the L-shaped galley on starboard and the dinette on port. The dinette seats four and converts to a 75 in × 43 in double berth. Storage is provided beneath the seats and in surrounding lockers and shelves.

The galley features deep double sinks outboard, a full-height refrigerator aft, and counter space extending around to the stove. Storage includes double doors beneath the sinks, two stacks of four drawers, pot-and-pan storage beneath the refrigerator, a spice-rack shelf above the sink, drawers beneath the stove, and three shelved lockers above it.

Five overhead lights and three opening ports serve the galley and dinette. Headroom is 7 ft.

Salon

Enter the salon from the sundeck or through the starboard side door beside the lower helm. Several sundeck-entry steps contain storage. The L-shaped seating/dinette accommodates four and can be removed to reconfigure the space. Its teak table has a starburst inlay, drop leaves, and adjustable height; it can also be removed without damaging the cabin sole.

A large fiddled shelf/counter sits aft of the L-shaped settee. Forward on port, the entertainment center includes an L-shaped counter, a double-door shelved locker, three drawers, and a TV with another drawer below, storage behind, and a fiddled shelf above. A liquor cabinet with storage beneath it occupies the aft port side.

Headroom is 6 ft 7 in. Five fixed forward windows and screened sliding side windows provide light and ventilation, supplemented by four overhead lights and LED strips behind the port and starboard valances.

Hull Work

Marsh Harbor Boatworks peeled and rebuilt the bottom and keel to repair blisters in 2016. The work added four layers of fiberglass and five coats of Interlux 2000 barrier paint, at a reported cost of $20,000.

Engine Hours and Service Records

Both main engines and the generator were inspected and serviced by Blue Water Marine in 2025.

Engine-hour clarification: The engine specifications list 3,967 hours for Engine 1 and 3,866 hours for Engine 2. The older mechanical description reports approximately 3,000 hours, with 2,900 hours last reported by the previous owner. It also lists newer hour-meter readings of 1,217 port and 1,278 starboard, and main tachometer readings of 280 port and 253 starboard. These readings are not reconciled in the listing; confirm actual operating hours and meter history before purchase.
