Arrangements for the use of radio while in foreign territorial waters will be in accordance with which instruction?

• A. Foreign Port Calls COMDTINST 3128.1
• B. Basic Operational Communications Doctrine NWP 6-01
• C. CG Regulations COMDTINST M5000.3
• D. Freedom of Information and Privacy Acts Manual COMDTINST M5260.3

Answer: (A)

Arrangements for radio use in foreign territorial waters are governed by guidance that specifically addresses interacting with foreign ports and authorities. The Foreign Port Calls instruction directs the procedures for communications and coordination when a vessel operates under foreign jurisdiction, including how radio operations should be handled in those situations. This direct focus makes it the appropriate reference for radio arrangements in foreign waters, rather than general operating doctrine, broad Coast Guard regulations, or privacy/FOIA manuals, which cover different topics and do not address foreign port communications in detail.
