MACKINAC ISLAND, Mich. (Michigan News Source) — When one company owns both ferry lines, controls both docks, and sets all the prices, Mackinac Island says it’s no longer fair transit—it’s a monopoly.

The city filed a federal countersuit earlier this month, accusing Hoffmann Marine—the parent company of Shepler’s and the Mackinac Island Ferry Company—of eliminating competition and attempting to impose identical fare increases for the 2025 season.

Now, city officials say they are heading to court to defend their authority over ferry and parking regulations following the consolidation of ferry services under the one Florida-based owner.

The countersuit follows a complaint filed in March by Shepler’s, which accused the city of overreaching its authority on fares, parking, and scheduling, according to The Detroit News.

Mackinac Island responded by citing its charter, approved by the Michigan Legislature, which gives the city exclusive authority to regulate ferry operations  and pricing when competition no longer exists.

Parking has also emerged as a key issue. The city rejected the companies’ proposed 2025 parking rates and ordered them to remove the prices from websites and ads until approved.

The case is pending in the U.S. District Court for Michigan’s Northern Division.
