(For other ships with the same name, see List of ships named SS Great Western.) SS Great Western of 1838, was an oak-hulled paddle-wheel steamship, the first steamship purpose-built for crossing the Atlantic, and the initial unit of the Great Western Steamship Company. She was the largest passenger ship in the world from 1837 to 1839. Designed by Isambard Kingdom Brunel, Great Western proved satisfactory in service and was the model for all successful wooden Atlantic paddle-steamers. She was capable of making record Blue Riband voyages as late as 1843. Great Western worked to New York for 8 years until her owners went out of business. She was sold to the Royal Mail Steam Packet Company and was scrapped in 1856 after serving as a troop ship during the Crimean War.
