A vessel ``documented * * * under the laws of the United States'' is
typically
a vessel which has been registered, enrolled and licensed, or licensed
by the Bureau of Customs under the laws of the United States (46 U.S.C.
11, 193, 251-252, 258, 840). Although Bureau of Customs regulations
provide for three types of documentations, distinctions between the
categories of vessels subject to them are immaterial for the purposes of
the Fair Labor Standards Act, since a vessel with any of the three kinds
of documentation is an ``American vessel'' within the section 3(p)
definition. Generally, any vessel of five net tons or more which is
owned by a citizen of the United States is ``entitled to''
documentation. Complete information on the documentation requirements
may be found in 19 CFR part 3.
