A Coast Guard Documented vessel is not required to have either Name or Registration numbers displayed on the bow. However it must have a
Name and
Hail Port on the transom, or near the stern on a double ender. The Hail Port is "supposed" to be a legal "U.S. Port of Entry", such as Boston, Portsmouth, etc...although many people do not adhere to the hail port rule.
A Documented vessel is required to have its Documentation Numbers and registered Tonnage permanently engraved or attached to a major frame or bulkhead inside the vessel.
