Michigan Takes Aim at Mackinac Island Ferry Monopoly in Antitrust Fight

According to a November report by MLive, the attorney general has filed a lawsuit seeking to break up the monopoly over passenger ferry transportation to the island.

The action comes after years of consolidation left the island’s commercial passenger ferry operations under common ownership, raising concerns among local officials about pricing and the availability of competing services.

Hoffmann Marine, part of the Hoffmann business group, acquired Shepler’s Mackinac Island Ferry in 2022 and the Mackinac Island Ferry Company in 2024, according to previous MLive reporting. The acquisitions brought the island’s two principal ferry operators under the same corporate umbrella.

The dispute has significant implications for Mackinac Island’s tourism-dependent economy. The destination draws more than 1 million visitors annually, with ferries providing the primary means of transportation between the island and mainland Michigan.

Rising Costs Intensify Competition Concerns

The consolidation has drawn scrutiny as ferry customers face higher transportation expenses.

MLive reported in July 2025 that the minimum cost of traveling to Mackinac Island had increased by roughly 50% following the consolidation of ferry ownership. In addition to higher ticket prices, customers faced new or increased charges associated with parking and online reservations.

The company has defended its pricing decisions, citing higher operating expenses and investments in its fleet and infrastructure. Hoffmann representatives previously said the business had spent approximately $6 million repairing and upgrading vessels and facilities associated with the Mackinac Island Ferry Company, according to MLive.

The dispute has also raised questions about how much authority local governments should have over privately operated transportation services that provide essential access to tourist destinations.

Legal Battle Over Regulatory Authority

The latest reported state action follows a separate legal confrontation between the ferry operators and Mackinac Island officials.

That dispute began in 2025 after city officials attempted to restrict fare increases. The ferry companies challenged the city’s authority to regulate their pricing, while the municipality pursued antitrust allegations related to the consolidation.

A federal judge dismissed the city’s antitrust claims in March 2026, although disagreements over regulatory authority continued.

Michigan lawmakers subsequently approved legislation expanding the city’s potential oversight of ferry operations, including parking, baggage and other charges.

Gov. Gretchen Whitmer signed the legislation in June, and Mackinac Island voters approved the necessary charter amendment on Nov. 3, according to reporting by Michigan Public and Spectrum News.

The regulatory changes give city officials broader authority over ferry-related fees but do not, by themselves, establish competing ferry operations.

Tourism Economy Faces Uncertainty

The conflict has highlighted the economic importance of ferry transportation to Mackinac Island, where tourism supports hotels, restaurants, retailers and other businesses.

Earlier this year, Nessel urged the city and Hoffmann Marine to pursue mediation after the company indicated it might discontinue operations when existing agreements expire in 2027.

In an April statement, the attorney general warned that prolonged litigation could undermine the interests of residents, businesses and visitors. She encouraged the parties to negotiate an arrangement that would preserve reliable transportation to the island.
