Iron screw steamship
Brunel's SS Great Britain unites an iron hull and a propeller for ocean crossings.
Launched in 1843, Isambard Kingdom Brunel's SS Great Britain was the first iron-hulled, screw-driven ship to cross the Atlantic, in 1845. At 98 m she was the longest ship in the world. Iron and later steel hulls allowed ships far bigger than wood could support.
