Shackleton now had the money to proceed. He acquired, for £14,000 (current value £), a 300-ton barquentine called "Polaris", which had been built for the Belgian explorer Adrien de Gerlache for an expedition to Spitsbergen. This scheme had collapsed and the ship became available. Shackleton changed her name to , reflecting his family motto, "By endurance we conquer". For a further £3,200 (current value £), he acquired Douglas Mawson's expedition ship , which was lying in Hobart, Tasmania. This would act as the Ross Sea party's vessel.
