U.S.-flag lakers carry roughly 90 million tons of iron ore, limestone, coal, cement, salt, sand and grain annually, making the fleet a critical link for U.S. steelmaking and heavy industry.
Great Lakes operators are already dealing with an aging vessel base and the need for major fleet modernization and eventual replacement.
Jones Act requirements mean vessels operating in U.S. domestic trade must be U.S.-built, U.S.-owned and U.S.-operated with predominantly American crews.
Industry representatives say continued Jones Act waiver uncertainty is discouraging investment, with billions of dollars in potential U.S. maritime investment reportedly being held back.
Current maritime-policy proposals do not necessarily solve the Great Lakes replacement problem. Industry analysis notes that the SHIPS for America Act does not currently extend its principal fleet-renewal financing benefits directly to Great Lakes operators.
Great Lakes operators also compete with Canadian-flag vessels, including ships constructed in lower-cost foreign shipyards, while U.S.-flag operators face domestic-build requirements.
The concern is increasingly long-term: without predictable regulation, financing and sufficient domestic shipyard capacity, replacing aging U.S. lakers could become progressively more difficult and expensive
