The U.S. Coast Guard issued a Notice interpreting the phase “international voyage” for purposes of its
maritime security regulations. For purposes of vessel security, the Coast Guard will consider that each voyage of a U.S. vessel originates at a port in the United States regardless of when the voyage actually began. Therefore, each U.S. vessel that otherwise meets the applicable tonnage requirements in SOLAS and is operating in waters of another country must meet ISPS requirements and obtain an International Ship Security Certificate (ISSC). This interpretation is effective immediately, but comments may be submitted on or before July 6, 2004. 69 Fed. Reg. 17927 (HK Law).
