SUPPLEMENTARY INFORMATION:

The Coast Guard will enforce the special local regulations in 33 CFR 100.1103, Table 1 to § 100.1103, Item number 6 for the Escape From Alcatraz Swim regulated area from 7 a.m. to 9 a.m. on June 9, 2024. This action is being taken to provide for the safety of life on navigable waterways during this event. Our regulation for marine events within Northern California, § 100.1103, specifies the location of the regulated area for the Escape From Alcatraz Swim which encompasses portions of the San Francisco Bay. During the enforcement period, the regulated area will be in effect in the navigable waters, from surface to bottom, defined by a line drawn from Alcatraz Island to Saint Francis Yacht Club.

During the enforcement period, under the provisions of 33 CFR 100.1103(b), if you are the operator of a vessel in the regulated area you must comply with directions from the Patrol Commander (PATCOM) or any other Official Patrol, defined as a Federal, State, or local law enforcement agency on scene to assist the Coast Guard in enforcing the regulated area. The PATCOM or Official Patrol may, upon request, allow the transit of commercial vessels through regulated areas when it is safe to do so.

In addition to this notification of enforcement in the Federal Register , the Coast Guard plans to provide notification of this enforcement period via the Local Notice to Mariners. If the Captain of the Port determines that the regulated area need not be enforced for the full duration stated in this notice, a Broadcast Notice to Mariners or other marine broadcast may be used to grant general permission to enter the regulated area.
