The Michigan House passed Senate Bill 304 on Thursday by a 91-16 vote, with all opposition coming from Republicans. The state Senate approved the measure last summer according to Bridge Michigan.

The bill now heads to Gov. Gretchen Whitmer for consideration. If signed, the change would still require approval from Mackinac Island residents because it amends the city charter.

Expanded authority over ferry operations

Under the legislation, the Mackinac Island City Council would be authorized to regulate multiple aspects of ferry service between the mainland and the island, including:

• Passenger ticket pricing
• Parking rates on the mainland
• Baggage handling fees
• Other operational elements tied to ferry service

The expansion comes amid ongoing legal and regulatory disputes involving ferry pricing and competition concerns tied to the island’s transportation system.

Opposition from neighboring communities

Officials in Mackinaw City and St. Ignace have opposed the legislation, arguing it would extend island regulatory authority into their jurisdictions, particularly regarding parking fees and related tourism infrastructure costs.

Mackinaw City officials were also expected to consider a resolution imposing a $200,000 fee on ferry operators to offset costs tied to tourism-related policing and road maintenance.

Ferry operator Hoffman Marine, which owns Shepler’s Inc. and Arnold Transit, has also expressed opposition to the measure.

In a statement, the company said its pricing “reflects the realities of increased fuel, labor, maintenance, and infrastructure expenses,” and warned that regulatory limits could affect long-term service quality and investment.

Ongoing legal dispute over ferry control

The legislation comes as Mackinac Island and Hoffman Marine continue to battle in federal court over ferry pricing authority and claims of monopoly control.

Hoffman Marine purchased both ferry services in 2004. Since then, ticket prices have increased from about $36 to as high as $39, according to reporting.

The dispute centers on whether the island’s limited ferry access structure constitutes a monopoly that allows the city to regulate pricing. A federal appeals court has allowed the island to control ticket prices temporarily but blocked authority over parking while litigation continues.

Next steps

The bill now awaits action from Gov. Gretchen Whitmer. If signed, it would move to a local referendum requiring Mackinac Island voter approval before taking effect, extending the ongoing debate over ferry governance, pricing authority, and regional tourism costs.

The Takeaway

• The Michigan House approved legislation expanding Mackinac Island’s regulatory authority over ferry fares, parking, and related operations.
• Neighboring cities and ferry operator Hoffman Marine oppose the bill, citing concerns over jurisdiction, costs, and operational impacts during ongoing legal disputes.
• The measure now heads to the governor and could still require approval from island voters before becoming law, leaving final implementation uncertain.
