Background
In 1843, the gunship USS Michigan, built in Erie, Pennsylvania, became the first iron-hulled vessel built on the Great Lakes. In the mid-1840s, Canadian companies began importing iron vessels prefabricated by shipyards in the United Kingdom. However, it would not be until 1862 that the first iron-hulled merchant ship, Merchant, was built on the Great Lakes. Despite the success of Merchant, wooden vessels remained preferable to iron ones until the 1880s, due to their inexpensiveness, and the abundance of timber. In the early 1880s, shipyards around the Great Lakes began to construct iron ships on a relatively large scale; in 1882, Onoko, an iron freighter, temporarily became the largest ship on the lakes. In 1884, the first steel freighters were built on the Great Lakes, and by the 1890s, the majority of ships constructed on the lakes were made of steel.
