What do ships on the Great Lakes do?

Ships on the Great Lakes, often referred to as “lakers,” play a crucial role in the region’s economy. These vessels are uniquely designed to navigate the Great Lakes and the St. Lawrence Seaway, covering a total distance of almost 4000 km.

Their primary purpose is to transport bulk cargoes such as limestone, iron ore, grain, coal, or salt from the mines and fields of the upper Great Lakes to various destinations. In 2006 alone, the 63 commercial ports on the Great Lakes handled 173 million tons of cargo.

The design of these ships is long and flat, allowing them to carry large amounts of cargo efficiently. Since the late 19th century, lakers have been an integral part of the region’s commerce. However, the navigation season is not year-round due to winter ice on the lakes. The Soo Locks and Welland Canal close from mid-January to late March, during which most boats are laid up for maintenance.

In addition to commercial activities, some vessels patrol the Great Lakes to ensure safety and law enforcement. They protect the lakes from illegal activities such as smuggling and drug trafficking, and assist with search and rescue operations.

Despite the advent of other transportation modes like railroads and highways, Great Lakes shipping remains vital. Each year, more than 160 million tons of waterborne cargo is transported within the region or to overseas destinations. So, whether it’s transporting goods or ensuring safety, ships on the Great Lakes continue to serve a pivotal role in the region’s economy and security.
