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 "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles.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".
Icicle (yacht)
Icicle is the name of the largest ice yacht ever built. It was built for John Aspinwall Roosevelt for racing on the Hudson River, New York state in 1869.
It was 21 metres (68 ft 11 inches) long and carried 99 m² (1070 ft²) of canvas. The yacht is still, nearly 140 years later, recognized by the "Guinness Book of Records" as a world record.
