5. Enrollment and Registration.—
When the ship is completed, she should be registered or enrolled as an American vessel. These words are synonymous; vessels in the foreign trade are "registered" and those in the domestic or coastwise trade are "enrolled"; (The Mohawk, 3 Wall. 566; Huus v. Co., 182 U. S. 392, 395). Vessels of less than twenty tons and more than five tons are neither registered or enrolled but should be licensed.
