USCG National 3rd Mate Unlimited
A Third Mate is a licensed officer in the deck department of a merchant ship. The third mate is an OICNW watchstander and customarily the ship's safety officer. Other duties vary depending on the type of ship, its crewing, and other factors.
The STCW International endorsement for a 3rd Mate is II/1 Officer in Charge of a Navigational Watch (OICNW). This is the same endorsement as 2nd Mate, as the next STCW increase in scope comes at the Chief Mate Level.

The applicant for an officer endorsement, whether original, renewal, duplicate, or raise of grade, must establish to the satisfaction of the Coast Guard that he or she possesses all the qualifications necessary (including but not limited to age, experience, character, physical health, citizenship, approved training, professional competence, and a test for dangerous drugs) before the Coast Guard will issue to him or her a merchant mariner credential (MMC). An applicant for any STCW endorsement must hold the appropriate national endorsement unless otherwise specified.
English language requirements.
An applicant for a 3rd Mate Officer Endorsement must demonstrate an ability to speak and understand English as found in the navigation rules, aids to navigation publications, emergency equipment instructions, machinery instructions, and radiotelephone communications instructions.
Experience and service.
An applicant for a national officer endorsement must have at least 3 months of required service on vessels of appropriate tonnage or horsepower within the 3 years immediately preceding the date of application.
No original officer endorsement may be issued to any naturalized citizen based on less experience in any grade or capacity than would have been required of a citizen of the United States by birth.
Experience and service acquired on foreign vessels is creditable for establishing eligibility for an officer endorsement, subject to evaluation by the Coast Guard to determine that it is a fair and reasonable equivalent to service acquired on merchant vessels of the United States, with respect to grade, tonnage, horsepower, waters, and operating conditions. An applicant who has obtained qualifying experience on foreign vessels must submit satisfactory documentary evidence of such service (including any necessary translation into English).
No applicant for an original officer endorsement who is a naturalized citizen and who has obtained experience on foreign vessels will be given an original officer endorsement in a grade higher than that upon which he or she has actually served while acting under the authority of a foreign credential.
Experience acquired while the applicant was less than 16 years of age is generally not creditable. Compelling circumstances and unique experiences acquired before the applicant reaches 16 years of age will be evaluated on a case-by-case basis.
No officer endorsement may be issued to any person who is not a citizen of the United States with the exception of operators of uninspected passenger vessels that are not documented under the laws of the United States.
Persons serving or intending to serve in the merchant marine service are encouraged to take the earliest opportunity to ascertain, through examination, whether their visual acuity, color vision, hearing, and general physical condition, are such as to qualify them for service in that profession. Any physical impairment or medical condition that would render an applicant incompetent to perform the ordinary duties required of an officer is cause for denial of an officer endorsement.
Applications for an original officer endorsement, raises of grade, and extensions of route, must be current and up to date with respect to service and the physical examination, as appropriate. Physical examinations and applications are valid for 12 months from the date the application is approved.
An individual may apply for an original officer endorsement, or officer or STCW endorsement of a different type, while on probation as a result of administrative action. The offense for which the applicant was placed on probation will be considered in determining his or her fitness to hold the endorsement applied for. An officer or STCW endorsement issued to an applicant on probation will be subject to the same probationary conditions as were imposed against the applicant's other credential. An applicant may not take an examination for an officer or STCW endorsement during any period of time when a suspension without probation or a revocation is effective against the applicant's currently held license, merchant mariner document (MMD), or MMC, or while an appeal from these actions is pending.
If information about the applicant's habits of life and character is brought to the attention of the Coast Guard after an original license, certificate of registry, or officer endorsement has been issued, and if such information reasonably supports the conclusion that the applicant cannot be entrusted with the duties and responsibilities of the license, certificate of registry, or officer endorsement issued, or indicates that the application for the license, certificate of registry, or officer endorsement was false or incomplete, the Coast Guard may notify the holder in writing that the license, certificate of registry, or officer endorsement is considered null and void, direct the holder to return the credential to the Coast Guard, and advise the holder that, upon return of the credential, the appeal procedures.
Applicants for an original officer endorsement in the following categories must present a certificate of completion from a firefighting course of instruction that has been approved by the Coast Guard. The firefighting course must have been completed within the past 5 years, or if it was completed more than 5 years before the date of application, the applicant must provide evidence of maintaining the standard of competence in accordance with the firefighting requirements for the credential sought.
The following categories must meet the requirements for Basic and Advanced firefighting in Regulations VI/1 and VI/3 of the STCW Convention and Tables A-VI/1-2 and A-VI/3 of the STCW Code.
