Vessels of five net tons or more used in fishing activities on navigable waters of the U.S. or in the Exclusive Economic Zone (EEZ), or used in coastwise trade must be documented unless the vessel is exempt from the documentation. The easiest way to get the documentation process started is by performing a vessel documentation search. Coastwise trade is generally defined as the transportation of merchandise or passengers between points in the U.S. or the EEZ. In addition, towboats operating between points in the U.S. or the EEZ or between the EEZ and points in the U.S. and dredges operating in the U.S. or the EEZ must be documented.
