The MV Manx Viking / Nindawayma was a passenger, truck and car ferry, whose last active service was on Lake Huron, operated by the Owen Sound Transportation Company; under contract to the Ontario Ministry of Transportation. In Canadian service she served the Highway 6 route between Tobermory and South Baymouth, Manitoulin Island from 1989 to 1992 alongside the MS Chi-Cheemaun. Service history One of three sister ships, she was launched on 19 August 1974 as the Monte Cruceta at the "S. A. Juliana Gijonesa" shipyard in Gijón, Spain, for the Spanish shipping line Naviera Aznar. The vessels were built as long-distance multi-purpose roll-on/roll-off (RORO) ferries, handling both cargo and passengers, with fully refrigerated vehicle decks. Outfitting delays postponed her maiden voyage until 1976, by which time she had been renamed as Monte Castillo. The ships ran a summer service in the Mediterranean, and in the winter carried fruit and vegetables across the Bay of Biscay to Liverpool and Newhaven from Spain and the Balearic Islands By 1977, the service across the Bay of Biscay for which they were built had ceased, the ships were sold: Monte Castillo was sold to Manx Line (later Sealink-Manx Line) and renamed Manx Viking for service between Heysham, England and Douglas, Isle of Man. Following a controversial reverse takeover in 1986 by the Isle of Man Steam Packet company, she worked a season painted in Steam Packet livery, initially alongside the Mona's Isle (ex-Free Enterprise III) followed by Antrim Princess (subsequently renamed Tynwald) before Manx Viking'''s lease was terminated and she was returned to her owners (the parent Sealink company, by now part of Sea Containers, who had actually funded the takeover). In 1987, she was briefly renamed Manx for the delivery voyage to new Norwegian owners Det Stavangerske Dampskibsselskap, for whom she sailed in service under the name Skudenes. The ship was sold again in 1989, into service with the Government of Ontario. She was renamed Ontario No.1 for the Atlantic crossing before her final renaming as MS Nindawayma.Her sisters were sold to Trasmediterranea for Mediterranean service.
