Coast Guard Establishes Temporary Safety Zone for Final Voyage of SS United States

The United States Coast Guard has implemented a temporary moving safety zone to regulate marine traffic during the upcoming transit of the historic former ocean liner SS United States. Published in the Federal Register, the rule establishes a 100-yard protective buffer around the vessel and all associated towing craft as they move from Mobile, Alabama, through regional waterways and into the Gulf of America. The operation marks the final chapter for the iconic vessel, which is slated to be transformed into an artificial reef.

Background and Operational Scope

The maritime operation involves a dead ship tow, meaning the SS United States will be propelled entirely by tugboats and auxiliary vessels without active propulsion or steering systems of its own. Captain M.O. Vega, serving as the Captain of the Port for Sector Mobile, determined that the transit poses distinct navigational hazards. These risks include the severely restricted maneuverability of the towing configuration, potential wake disruptions from passing commercial and recreational traffic, and heightened vessel congestion within the Mobile River Channel and Mobile Bay.

The safety zone is formally codified under Title 33 of the Code of Federal Regulations, specifically in part 165. The regulatory framework relies upon statutory authority granted by 46 U.S.C. 70034, which empowers the Department of Homeland Security and the Coast Guard to establish safety zones for maritime protection. The designated area covers all navigable waters within a 100-yard radius of the vessel and supporting craft. The enforcement window spans from November 6, 2026, through November 16, 2026, though the restrictions will only be actively enforced during the actual transit from the pier in Mobile until the convoy reaches the United States Territorial Sea boundary located approximately 12 nautical miles offshore of Destin, Florida.

Procedural Waivers and Legal Justification

In promulgating the rule, the Coast Guard invoked provisions allowing for the omission of standard notice and comment procedures. Under the Administrative Procedure Act at 5 U.S.C. 553(b)(B), agencies may bypass the notice of proposed rulemaking when good cause demonstrates that such procedures are impracticable, unnecessary, or contrary to the public interest. Federal officials noted that the scheduling details for the complex towing operation were not finalized until October 20, 2026, leaving insufficient time to publish a traditional proposal prior to the planned departure timeline. Similarly, the agency invoked 5 U.S.C. 553(d)(3) to make the rule effective less than 30 days after publication, citing the immediate necessity to safeguard personnel and the marine environment.

To ensure public awareness without a lengthy prior comment period, the Captain of the Port Sector Mobile will issue Broadcast Notices to Mariners via marine VHF-FM channel 16. These advisories will provide local mariners with precise dates and enforcement intervals prior to departure. Unauthorized entry into the 100-yard safety zone is strictly prohibited. Individuals or vessel operators seeking transit authorization must contact the Captain of the Port or a designated representative on channel 16 or via telephone.

Regulatory and Environmental Assessments

In accordance with federal rulemaking guidelines, the Coast Guard conducted various administrative reviews. The rule is exempt from the Regulatory Flexibility Act analysis because the underlying notice and comment requirements were waived for good cause. Furthermore, agency officials certified that the action does not impose unfunded mandates exceeding 100 million dollars under the Unfunded Mandates Reform Act of 1995, nor does it disrupt federalism principles or tribal governance under relevant executive orders.

From an environmental perspective, the action falls under Department of Homeland Security Directive 023-01, Revision 1, and implementing instructions for the National Environmental Policy Act. The establishment of a temporary safety zone is categorically excluded from further environmental review under paragraph L60(a) of the relevant DHS instruction manual, as it represents a routine safety measure without cumulative significant effects on the human environment.

Operational Trajectory and Next Steps

As maritime authorities finalize preparations, the exact departure date of the SS United States remains dependent on favorable weather and sea conditions within the region. The cooperative efforts between federal regulators, towing contractors, and local maritime stakeholders highlight the logistical complexities inherent in large-scale marine salvage and reefing projects. The successful execution of the safety zone enforcement will depend on adherence by local mariners to the broadcasted navigational advisories issued by Sector Mobile.
