Nuclear-powered icebreaker
On 17 August 1977, NS "Arktika" ("Arctic") became the first surface ship ever to reach the North Pole. "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles. Rather than be scrapped, there are calls for her to be converted to a museum ship, like her predecessor "Lenin".
Crystal Serenity
Crystal Serenity was the largest cruise ship ever to navigate the Northwest Passage. Starting on 10 August 2016, the ship sailed from Vancouver to New York City with 1,700 passengers and crew, taking 28 days for the journey. In the Canadian Arctic it successfully made stops at Ulukhaktok and Cambridge Bay on Victoria Island, then passed up Franklin Strait and through the narrow Bellot Strait, adjacent to Zenith Point, the most northerly extension of North America. It explored Beechy Island where Franklin overwintered, followed by seldom visited fjords on the south side of Devon Island, plus fjords on Baffin Island and the village of Pond Inlet. On Sept. 5, 2016 it sailed for Disko Bay in Greenland. Her transit triggered comments on Canada's Arctic sovereignty.
