This 1976 Viking 40 Sedan is a fiberglass convertible powered by twin Detroit Diesel 671N engines delivering 310 horsepower each, with a cruising speed of 15 knots and a top speed of 17 knots. The boat spans 40 feet in length with a 14-foot beam, providing a substantial platform suited to extended cruising and fishing.
The interior follows a two-stateroom layout with the galley to starboard, master stateroom to port with queen berth, and a forward vee berth with filler. Both staterooms connect to the single head, fitted with an electric Raritan toilet and Lectrasan sanitation system. The galley features Corian counters and custom cabinetry with teak and holly flooring in the lower cabin. Two-zone air conditioning keeps the interior comfortable, with dual Marinaire and Pompanette units providing 16,000 BTU each.
The engine room has undergone three complete refits—in 1993, 2004, and 2024—and includes a 7 kW Kubota genset. A hydraulic lift cover exposes the engines for inspection and maintenance. The starboard engine shows 50 hours since major overhaul, while the port engine has 1,150 hours. New starting batteries were installed in 2024, along with recent replacements of AC water pumps and sanitation hoses.
Topside and cabin areas received a fresh Awlgrip paint in 2024. The fishing-focused convertible layout includes two six-foot fishboxes with macerators, a tuna tower with rod holders and spreader lights, and triple Rupp spreader outriggers. An electric davit on the bow can accommodate a 13-foot dinghy. Electronics include Furuno radar, VHF radio, and Garmin Chartplotter 94SV.
