Master 100-ton & OUPV License info

The OUPV (Operator of Uninspected Passenger Vessel), commonly known as the 6-pack captain’s license is most popular with fishing guides and small tour boats. The operator is limited to a maximum of six passengers on a small uninspected passenger vessel less than 100 GRT (about 65-feet).

The Master less than 100 GRT is a superior captain’s license to the OUPV. Meaning it allows the operator to carry more than six passengers when operating an inspected passenger vessel. In addition, the Master’s license allows the holder to be captain of crew boats, workboats, supply boats, ferries, and other vessels as well. Lastly, the Master’s license provides an easier path for the license to grow with your experience.

To qualify for any captain’s license – OUPV (six-pack) or Master less than 100 GRT – you must meet these requirements:

  • Have at least 90-days of sea service within the past seven years (recency). Additional experience is required but varies by license and route.
  • First Aid / CPR required for an original issue (per checklist).
  • Complete an approved class or take the exams at a US Coast Guard Regional Exam Center.

Additionally, tonnage limitations based on your qualifying experience apply to the Master’s license. For specific information, tap one of the links below to download the checklist from the National Maritime Center (NMC) website.
