Enrollment
A marine document issued to a vessel of the United States by the customs officials. Vessels of twenty tons and upward engaged in domestic trade, in the fisheries, or in foreign trade on the inland northern frontiers of the United States, must (if they are not under register) be enrolled. But an enrolled vessel cannot engage in foreign trade by sea. The enrollment identifies the vessel in the following particulars: nationality, official number, ownership, vessel's name, home port, name of master, year of building, place of building, name of the measurer, number of decks, number of masts, rig of vessel, dimensions, and tonnage. The enrollment continues in force indefinitely, unless the rig of the vessel, or the tonnage of same, or the ownership changes, in which case a new enrollment must be obtained. Yachts may be enrolled, although it is not compulsory.
