Coast Guard Sets Temporary Waterway Rules for Air Show Baltimore in 2026

The Coast Guard is updating a regulation to create a temporary safety zone in Baltimore’s Inner Harbor and Patapsco River. The zone will be active from June 24 through July 1, 2026, to accommodate Air Show Baltimore, Fleet Week 2026, and Sail250.

Why it matters: This is a routine scheduling update to keep the waterway safe while aircraft perform low-flying maneuvers over a coordinated series of public events. It gives commercial and recreational boaters advance notice so they can adjust their routes, and it establishes a clear point of contact for vessels that must transit the area for work or logistics.

Who it affects

• Boat operators and mariners planning to transit Baltimore’s Inner Harbor and Patapsco River between June 24 and July 1, 2026

This final rule was published by the Coast Guard in the Federal Register; mariners and event organizers should verify the exact coordinates and contact procedures in the original document before making transit plans.
