Overview:  A state of the art boat when she was introduced in 1989, the Viking 57 Convertible was in production for two years before evolving into the now iconic Viking 58 Convertible (1991–2000). At the time, the 57C was the largest and most impressive boat in the Viking fleet, a design and engineering milestone that helped solidify Viking's hold of the fast-growing luxury sportfish market. The interior dimensions are impressive for a boat this size. Stepping inside through the starboard-side sliding door, the salon is dominated by a large L-shaped Ultraleather sofa to port with rod storage under. The galley is all the way forward, and a teak TV cabinet, wet bar and an L-shaped dinette are to starboard, across from the galley. Note that the master stateroom is forward in this layout rather than amidships as it is on most Viking convertibles. Both guest cabins have twin single berths, and a stacked washer/dryer unit is located in a companionway utility closet. Cockpit features include a tackle center, freezer, in-deck fish box, livewell, gunwale rod holders, and direct access to the standup engine room.

Power: The only engines offered in the Viking 57C were 1,080hp 12V92 Detroits (25 knots cruise/28–30 knots top).
