A seaman may start the process of attaining a license after three years of service in the deck department on ocean steam or motor vessels, at least six months of which as able seaman, boatswain, or quartermaster. Then the seaman takes required training courses, and completes on-board assessments. Finally, the mariner can apply to the United States Coast Guard for a third mate's license.
An alternate method of obtaining a license as a master of vessels of any gross tons upon oceans, without sailing as a third, second, or chief mate, is to obtain one year of seatime as a 1st class pilot of any gross tons or mate of vessels of any gross tons upon Great Lakes and inland waters. Then pass an examination for the license of master of vessels of any gross tons upon Great Lakes and inland waters. A master of vessels of any gross tons upon Great Lakes and inland waters may, without any additional seatime, take the examination for master of vessels of any gross tons upon near coastal waters. If the candidate does not already have sufficient deep sea experience he may with six months of additional seatime, in any licensed capacity, take a partial examination consisting primarily of celestial navigation and have the near coastal restriction removed. 46CFR 11.403
A master of 1,600 ton vessels can, under certain circumstances, begin the application process for an unlimited third mate's license.
If approved the applicant must then successfully pass a comprehensive license examination before being issued the license. Hawsepiper is a maritime industry term used to refer to an officer who began his or her career as an unlicensed merchant seaman, as opposed to earning his third mate's license by attending a maritime college or academy. The term derives from a ship’s hawsepipe, the opening on the ship's bow through which the anchor chain passes. A mariner is said to have "climbed up the hawsepipe," a nautical metaphor for climbing up the ship's rank structure. Since the requirements of STCW '95 have been enacted, there have been complaints that the hawsepiper progression path has been made too difficult because of the cost in time and money to meet formal classroom training requirements. These critics assert that the newer requirements will eventually lead to a shortage of qualified mariners, especially in places like the United States.
