Everything You Need To Know
- The United States Coast Guard (USCG) Master's captain's license authorizes the holder to operate both inspected and uninspected vessels. Inspected vessels are those certified by the USCG to carry more than six paying passengers plus crew. Examples include ferry boats, harbor tour boats, and whale-watching boats.
- Individuals who wish to operate inspected vessels that carry more than six passengers, such as charter boats, tour boats, or ferries in United States waters, must obtain a 25/50/100-Ton Master's captain's license.
- An inspected passenger vessel is a boat or ship that is required to comply with specific safety regulations set by the U.S. Coast Guard. These regulations cover construction standards, safety equipment, crew training, and operational guidelines. The vessel undergoes regular inspections to ensure adherence to these standards. The vessel will have a Certificate of Inspection (COI) onboard, which specifies the maximum number of paying passengers allowed and indicates the type of Master’s license required for operation.
- An uninspected vessel has less stringent requirements and typically carries six or fewer passengers for hire. In contrast, inspected vessels can carry more than six paying passengers and must adhere to strict construction, safety, equipment, and manning regulations.
- There are various versions of the Master's license. The USCG Master licenses available include the Master's Inland (authorizes operation on inland waters), the Master's Near Coastal (permits operation on inland waters and up to 200 miles offshore), and the Master's Near Coastal with Great Lakes (allows operation on inland waterways, the Great Lakes, and up to 200 miles offshore). The tonnage categories - 25, 50, or 100 tons - correspond to the maximum size of inspected vessels you can professionally operate; you will be restricted to 100 gross tons for uninspected vessels.
- To qualify, you must have adequate documented sea service time on vessels of appropriate tonnage, be at least 19 years old, and have U.S. citizenship. Additionally, you need a valid Transportation Worker Identification Credential (TWIC), successful completion of a USCG-approved Master-level course and proctored exam, and a physical examination and drug test. You must also hold a valid CPR and First Aid certification and pay the application fees to the Coast Guard.
- No, you are not required to progress sequentially through the tonnage categories. Based on your documented sea service experience on appropriately sized vessels, you may qualify directly for a 50- or 100-ton license.
- Sea service can be documented using official logs, letters from vessel owners or operators, or sea service forms that detail the capacity in which you served, the vessel(s) size, and the time spent on board.
- Yes, the USCG accepts military sea service, but you need to provide appropriate military documentation that certifies your role and time spent on vessels.
- Yes, under certain conditions, the time spent serving on foreign-flagged vessels may count. However, the NMC reviews these on a case-by-case basis. You must provide valid documentation of your service.
- The license is valid for five years. To renew it, you must demonstrate recent sea service or pass a Coast Guard-approved written requirement in lieu, undergo a physical examination, remain drug-free, and pay an application fee.
