Construction on the ship began in Greece on 11 September 2001 by Atsalakis-Sidironaftiki shipyard at their yard in Perama. The vessel was launched on 19 October 2002 with the name of Adamantios Korais. Due to unspecified delays during construction of the hull, work was delayed, and construction was not completed until 19 July 2004 and entered service as Sonia. During the construction period, one of the engines suffered a catastrophic failure.[2] The ship was first chartered by the Port Authority of Trinidad and Tobago to run the route between Port of Spain, Trinidad, and Scarborough, Tobago beginning in December 2004.[1] Sonia was brought in to replace the ageing ferry Beauport and to support the fleet's other ferry Panorama.[4] Ship operations were managed by International Shipping Partners. However, before beginning service, the Port Authority discovered 14 defects aboard the ship that required rectification before Sonia could sail.[5] The ship suffered further breakdowns and had an engine explode.[2] In 2006, the ship was renamed Sonia X. The ferry then operated out of Barcelona, Spain on a run to Ibiza.[2] The ferry was purchased by BC Ferries in September 2006 in a deal worth €35.7 million, or $50.6 million CAD. Sonia was acquired to replace the ferry which sank after running aground in March 2006.[6] [7]
The ship was painted in BC Ferries livery and sailed from Greece to Victoria, British Columbia via the Panama Canal.[8] The vessel arrived at the Victoria shipyards on 18 December 2006, where she underwent an $18-million refit and interior upgrade that finished in March 2007.[6] Part of the refit was to retrofit the ferry's stern loading ramp to match the dockside facilities at BC Ferries terminals.[3] Upon entering service Northern Adventure in April 2007[3] initially replaced Queen of the North on the Inside Passage route. However, when entered service in early 2009, was decommissioned and Northern Adventure was reassigned to replace Queen of Prince Rupert and her Haida Gwaii duties.[9] Northern Adventure sails two routes: the scenic Inside Passage route between Port Hardy and Prince Rupert and the Haida Gwaii crossing between Prince Rupert and Skidegate.
