The 1999 Viking 58 Convertible is a custom-refined sportfish built on Viking's proven offshore hull design. She was originally commissioned new and then taken to Merritt Boatworks for seven months of extensive customization, which included a full custom tower, mezzanine seating, teak cockpit decking and covering boards, a high-gloss teak rub rail, custom salon windows, custom galley, and custom dining table. Lifting rails were added to improve ride quality, handling, and efficiency in offshore conditions. The result merges Viking's mechanical reliability with Merritt's refined finishing and detailing.
Powered by twin MTU diesel engines producing 2,700 total horsepower, the boat cruises at 24 knots with a maximum speed of 30 knots. Three aluminum fuel tanks hold 1,800+ gallons, extending range beyond 1,000 nautical miles at economical cruise speeds. The layout provides three staterooms and three heads, suited for extended offshore voyages. Redundant systems include twin Onan 20–21 kW generators, redundant AC raw water systems, and a Sea Recovery watermaker with full filtration. Twin ZF transmissions, hydraulic steering, trim tabs, and dripless shaft logs support reliable long-distance operation.
The boat has benefited from consistent, well-documented maintenance. A professional hull repaint was completed in 2015, followed by annual haul-outs and regular waxing. Recent work includes propeller reconditioning and balancing, shaft and strut service, rudder resealing, propspeed application, complete bottom paint system, alternator replacements, new AC sea strainers, fire suppression system service, battery replacement, and davit service and refinishing. Interior updates in 2025 added new carpet throughout and a re-upholstered salon couch.
Navigation electronics include dual Garmin GPSMAP 8215 displays, Garmin GMI depth and wind instruments, a Simrad autopilot, dual ICOM IC-M602 VHF radios, a Ritchie compass, and VDO analog gauges with Detroit Diesel digital displays. The boat comes with a 2013 AB 13-foot dinghy and 40 HP Yamaha outboard.
