Title 46 › Subtitle Subtitle II— Vessels and Seamen › Part F— Manning of Vessels › Chapter 83— MASTERS AND OFFICERS › § 8304

Last updated Apr 5, 2026|Official source

Summary

Requires that masters, mates, and engineers on U.S.-documented vessels bound for the high seas must hold a license that authorizes the job. "High seas" means waters seaward of the Boundary Line. The rule follows the Officers’ Competency Certificates Convention, 1936, ratified September 1, 1938, and applies to documented ships on the high seas except public vessels, wooden primitive boats (like dhows or junks), barges, and vessels under 200 gross tons as measured under the cited statutes. A license issued under section 7101 is the certificate of competency. If someone hires or serves without the proper license, they face a $100 civil penalty. A designated official can detain a vessel about to leave a U.S. port for the high seas until it meets the rule. Foreign ships in U.S. waters may be detained and inspected. An appeal of a detention order must be filed within 5 days. Customs personnel may enforce the rule.
