British first-rates on the Great Lakes before 1812

How could the United States respond if Britain had two 112-gun first-rates and a 102-gun first-rate on the Great Lakes before the War of 1812?

It could not respond quickly enough; Britain's established ships, crews, and infrastructure would dominate anything improvised after the crisis began.

The United States is judged to have no quick military solution in this scenario. Peacetime British construction would provide seasoned timber, trained crews, dockyard support, and overwhelming local firepower before the Americans could build an equivalent force. Prewar infrastructure and readiness would matter more than theoretical American wartime shipbuilding potential.
