Though her hull looked from the outside like that of any other vessel of comparable size, it was not. As launched she had 10 passenger cabins, a spacious dining saloon and galley (with accommodation for two cooks), a smoking room, a darkroom to allow passengers to develop photographs, electric lighting and even a small bathroom.

Her original purpose was to provide luxurious accommodation for small tourist and hunting parties in the Arctic as an ice-capable steam yacht. She was 144 ft (44 m) long, with a 25 ft (7.6 m) beam, and measured 350 tons gross. The ship was launched on 17 December 1912 and was initially christened Polaris after the North Star. Every detail of her construction had been scrupulously planned to ensure maximum durability: for example, every joint and fitting was cross-braced for maximum strength. She was built under the supervision of master wood shipbuilder Christian Jacobsen, who was renowned for insisting that all men in his employment were not just skilled shipwrights but also experienced in seafaring aboard whaling or sealing ships. The wreck is designated as a protected historic site and monument under the Antarctic Treaty System.ĭesigned by Ole Aanderud Larsen, Endurance was built at the Framnæs shipyard in Sandefjord, Norway. She lies 9,869 feet (3,008 m 1,645 fathoms) deep, and is in good condition. The wreck of Endurance was discovered on 5 March 2022, nearly 107 years after she sank, by the search team Endurance22. All of the crew survived her sinking and were eventually rescued in 1916 after using the ship's boats to travel to Elephant Island and Shackleton, the ship's captain Frank Worsley, and four others made a voyage to seek help. A year later, she became trapped in pack ice and finally sank in the Weddell Sea off Antarctica on 21 November 1915.

After her commissioners could no longer pay the shipyard, the ship was bought by Shackleton in January 1914 for the expedition, which would be her first voyage. The ship, originally named Polaris, was built at Framnæs shipyard and launched in 1912 from Sandefjord in Norway.
