RRS Discovery in Antarctica

RRS Discovery was the last traditional wooden three-masted ship to be built in Britain. Designed for Antarctic research, she was launched as a Royal Research Ship (RRS) in 1901. Her first mission was the British National Antarctic Expedition, carrying Robert Falcon Scott and Ernest Shackleton on their first, successful journey to the Antarctic, known as the Discovery Expedition. She is now the centrepiece of visitor attraction in her home, Dundee. On 16 March 1900, in the context of significant donations to the approaching expedition by patrons Llewellyn W. Longstaff and the British Government, construction on the Discovery began in Dundee, Scotland, by the Dundee Shipbuilders Company. She was launched into the Firth of Tay on 21 March 1901 by Lady Markham, the wife of Sir Clements Markham, President of the Royal Geographical Society.

Discovery had coal-fired auxiliary steam engines, but had to rely primarily on sail because the coal bunkers did not have sufficient capacity to take the ship on long voyages. She was rigged as a barque. According to Shackleton, the ship was a bad sailer, and carried too much sail aft and not enough forward; while Scott worried that the design of the ship's hull was unsuitable for work in pack ice. The ship had a massively built wooden hull, made from five different types of wood to better withstand the compression of the icepack. The keel was made from the trunk of a single eucalyptus tree. The propeller and rudder could be hoisted out of the way to prevent ice damage and Iron-shod bows were severely raked so that when ramming the ice they would ride up over the margin and crush the ice with deadweight. The Discovery rolled badly in the open sea where the flat shallow hull, built with no protuberances to work well in ice, provided minimal stability in heavy seas.
