Of her three masts, the forward one was square-rigged, while the after two carried fore and aft sails, like a schooner. As well as sails, ''Endurance'' had a 350 horsepower (260 kW) coal-fired steam engine capable of speeds up to 10.2 knots (18.9 km/h; 11.7 mph). | Of her three masts, the forward one was square-rigged, while the after two carried fore and aft sails, like a schooner.

By the time of launch on 17 December 1912, ''Endurance'' was perhaps the strongest wooden ship ever built, with the possible exception of ''Fram'', the vessel used by Fridtjof Nansen and later by [[Roald Amundsen]]. However, there was one major difference between the ships: ''Fram'' was bowl-bottomed, which meant that if the ice closed in against her she would be squeezed up and out and not be subject to the pressure of the ice compressing around her. By contrast ''Endurance'' was designed with great inherent strength in her hull to resist collision with ice floes and to break through [[pack ice]] by ramming and crushing. However she was not intended to be frozen into heavy pack ice, and so was not designed to rise out of a crush. In such a situation she was dependent on the ultimate strength of her hull alone to resist the crushing pressure of ice around her. | By the time of launch on 17 December 1912, ''Endurance'' was perhaps the strongest wooden ship ever built, with the possible exception of ''[[Fram]]'', the vessel used by Fridtjof Nansen and later by [[Roald Amundsen]].
