Great Lakes Pilotage Rates-2027 Annual Review and Revisions to Methodology

In accordance with the Great Lakes Pilotage Act of 1960, the Coast Guard is proposing pilotage rates for the 2027 shipping season. We are conducting a full ratemaking for 2027. We are requesting comments on the Great Lakes pilotage ratemaking methodology, including one proposed update to that methodology. We also propose the pilotage rate for the Straits of Mackinac, newly designated for pilotage requirements by the National Defense Authorization Act for Fiscal Year 2026. The Coast Guard estimates that this proposed rule would increase operating costs by approximately 10 percent compared to the 2026 season.
