What kind of laws do USCG boarding officers primarily enforce?

USCG boarding officers primarily enforce federal maritime laws and regulations, which encompass a wide range of statutes aimed at ensuring the safety, security, and environmental protection of U.S. waters. This includes enforcing laws related to navigation, vessel operations, safety standards, and environmental compliance, such as regulations concerning oil spills and hazardous materials. The Coast Guard operates under the authority granted to it by federal law, and its primary mission involves safeguarding public interests on navigable waters and in coastlines, which aligns with federal jurisdiction.

While international trade laws and state fishery laws are relevant to maritime activities, they are not the main focus of the Coast Guard’s enforcement duties. Local environmental laws may apply in certain circumstances, but the USCG's mandate is rooted in federal jurisdiction, making federal maritime laws and regulations the core of its enforcement responsibilities.
