Expedition line Quark Expeditions claims to have completed more voyages to the North Pole than any other operator after sailing there for the 60th time.

Icebreaker ship, 50 Years of Victory, reached the North Pole just after midnight on June 19.

The expedition line also claims to have completed every sailing it has attempted to the North Pole since it embarked on its maiden voyage in 1991.

Quark Expeditions operates two to three voyages per year to the region typically in June when passengers have the best opportunity to see polar bears due to the long daylight hours and thick ice. 50 Years of Victory can break ice over two metres thick.
