Isambard Kingdom Brunel created a number of quite revolutionary steamships - the Great Western which was the first practical transatlantic paddle-steamer; the Great Britain, the first iron-built screw-driven liner; and the monster Great Eastern which remained the largest ship in the world for almost half a century. Besides these well-known wonders of the maritime world, Brunel also worked with the Admiralty on the introduction of the screw propeller into naval service. Although apparently well-known, the story of Brunel and his ships is surrounded by myth and self-created propaganda. In this book, a team of marine engineer, historian, and naval architect combine to analyse the scientific and economic context, the reality of Brunel's contribution, and the technical features of his ships. It is illustrated with original draughts, cutaway drawings and photographs.
