Licensing
United States
To become a master of vessels of any gross tons upon oceans in the United States, one must first accumulate at least 365 days of service while holding a chief mate's license. The chief mate's license, in turn, requires at least 365 days of service while holding a second mate's license, passing a battery of examinations, and approximately 13 weeks of classes. Similarly, one must have worked as a third mate for 365 days to have become a second mate. There are two methods to attain an unlimited third mate's license in the United States: to attend a specialized training institution, or to accumulate "sea time" and take a series of training classes and examinations.
Training institutions that can lead to a third mate's license include the U.S. Merchant Marine Academy (deck curriculum), the U.S. Coast Guard Academy and U.S. Naval Academy with qualification as an underway officer in charge of a navigational watch, any of the Five state maritime colleges in Maine, Massachusetts, New York, Texas, or California or the Great Lakes Maritime Academy, or a three-year apprentice mate training program approved by the Commandant of the U.S. Coast Guard.
