Pierce Butler, James Stewart Company v. Rivara…
“ The purpose of the enrollment of vessels is to give to them the privileges of American vessels as well as the protection of our flag. There is no foundation for the contention earnestly urged by plaintiff in error that Congress by these acts created 'a new form of property known as vessels of the United States' or that enrolled vessels are 'nationalized or federalized' in respect of conditional sale contracts such as the one here involved. ”
