Coast Guard Establishes Temporary Security Zones for Sail 250 on Lower Mississippi River

The Coast Guard is creating temporary security zones on the Lower Mississippi River in New Orleans for the Sail 250 event. The zones are active from 12:01 a.m. on May 24, 2026, through 11:59 p.m. on June 1, 2026.

Why it matters: This rule limits boat traffic and sets speed restrictions near the New Orleans riverfront for a specific week in 2026. It allows the Coast Guard to secure visiting vessels and manage crowds during Sail 250. For the rest of the year, the river remains open to normal navigation. The effect is narrow and tied directly to the event schedule.

Who it affects

• Vessel operators navigating the Lower Mississippi River between Mile Marker 92.7 and 98 during the event dates.
