No, it does not. Title 46 CFR Part 67 states: “The hailing port must be a place in the United States included in the U.S. Department of Commerce’s Federal Information Processing Standards Publication 55DC” and “the hailing port must include the State, territory, or possession in which it is located.”
Note: the “it” in the last sentence refers to the “hailing port” and not any vessel. The hailing port can be anywhere in America.
That said, “The Director, National Vessel Documentation Center has final authority to settle disputes as to the propriety of the hailing port designated.”
For more information about both the hailing port and hailing port marking requirements, the relevant laws can be read here.
