Vessels that do not operate on the navigable waters of the U.S. or in the fisheries in the EEZ, are exempt from the requirement to be documented. Also exempt are Coastwise qualified, non-self-propelled vessels used in coastwise trade within a harbor, on the rivers or lakes (except the Great Lakes) of the U.S., or the internal waters or canal of any state.Yes. A Certificate of Documentation may be endorsed for the fishery, coastwise, registry, or recreation. Any documented vessel may be used for recreational purposes, regardless of its endorsement, but a vessel documented with a recreational endorsement only may not be used for any other purpose. Registry endorsements are generally used for foreign trade.
