Merchant vessels are required to report their arrival in U.S. ports at least twenty-four hours in advance in accordance with which regulation?

• A. Title 33 CFR Part 124
• B. Title 46 CFR Part 350
• C. Title 14 CFR Part 92
• D. Title 47 CFR Part 10

Answer: (A)

The main idea is advance notice of arrival for ships entering U.S. ports. Merchant vessels are required to file a report at least 24 hours before arrival to give authorities time to coordinate inspections, berthing, and security measures, ensuring a smooth and safe port entry. This requirement is set out in Title 33, Part 124, which specifically covers the procedures and timing for reporting arrival. The 24-hour window helps U.S. Coast Guard and port authorities prepare resources and processing in advance.

The other regulations listed cover topics outside port-entry reporting. They pertain to different transportation modes or areas (such as aviation or telecommunications) and do not address the 24-hour arrival reporting requirement for ships.
