Sectional line drawing with wash (scale 1:24?) showing the early design of the oscillating paddle engines, by J Maudslay. The SS 'Great Britain' was the first screw-propelled vessel to cross the Atlantic, as well as being the first iron-built ship to do so. She sailed from Liverpool to New York in 1845, taking 14 days 21 hours to make the crossing. She was completed in Bristol in 1843 for the Great Western Steamship Company to the plans of Isambard Kingdom Brunel. Accommodation was provided for about 360 passengers. The Great Britain was employed in the Australian trade from 1852, and then had her engines removed and was converted into a sailing vessel in 1882. In 1970 she was brought back to the dock in which she was built, for preservation.
