Bastø Fosen

The company was established as a subsidiary of Fosen Trafikklag, and received concession to operate the ferries from 1995, after the former company Gokstad did not offer as good a deal for the authorities. For the first two years traffic was performed with two leased ships. In 2003, Bastø Fosen received concession for operations until 2015, after the Norwegian Public Roads Administration had rejected a competing offer from Stavangerske. The route is the only in the country not to receive any operating subsidies. Bastø Fosen used the concession extension as collateral for ordering the new ferry Bastø III. In 2008, Bastø Fosen announced they were interested in increasing the number of ferries to four. The Public Road Administration has launched plans to build a tunnel under the fjord to replace the ferries, estimated to cost 5 billion kr; in comparison a bridge would cost NOK 15 billion. A tunnel would have to be financed as a toll road.

Fosen Trafikklag merged to form FosenNamsos Sjø, with Bastø Fosen continuing as a subsidiary. Ownership passed to Torghatten when it bought FosenNamsos Sjø. During a corporate re-organization, they renamed Bastø Fosen to Torghatten Sør.
