Photograph of two men in the 'James Caird', one of whom is seated and the other standing with a third figure standing in the background. For Shackleton’s relief voyage to South Georgia the carpenter McNish went to work on the 'James Caird', the largest and most seaworthy of the three boats. He raised her sides and covered her over with a roof made from tent fabric to provide some shelter for the men crossing the southern ocean.
