As part of the Transglobe Expedition, Fiennes and Burton completed the Northwest Passage. They left Tuktoyaktuk on 26 July 1981, in an 18 ft open Boston Whaler and reached Tanquary Fiord on 31 August 1981. Their journey was the first open boat transit from West to East and covered around 3,000 miles (2,600 nautical miles or 4,800 km) taking a route through Dolphin and Union Strait following the south coast of Victoria Island and King William Island, north to Resolute Bay via the Franklin Strait and Peel Sound, around the south and east coasts of Devon Island, through Hell Gate and across Norwegian Bay to Eureka, Greely Bay and the head of Tanquary Fiord. Once they reached Tanquary Fiord, they had to trek a further 150 miles via Lake Hazen to Alert before setting up their winter base camp.
