(c) While operating in waters under the jurisdiction of the United States, the Coast Guard may board any vessel to which this subpart applies to determine that the vessel has the document(s) required by paragraph (a) of this section on board. Any foreign-flagged vessel found not to be in compliance with paragraph (a) of this section may be detained by order of the Captain of the Port at the port or terminal where the noncompliance is found until the COTP determines that the vessel can go to sea without presenting an unreasonable threat of harm to the port, the marine environment, the vessel, or its crew.
