An OUPV license — Operator of Uninspected Passenger Vessels — is a USCG-issued credential that authorizes you to take up to six paying passengers on uninspected vessels up to 100 gross tons. It's commonly called the "6-Pack" license and is the most popular first commercial license for charter captains in the U.S.

The USCG Master of Vessels license is the highest-tier commercial captain's credential for near-coastal and inlandoperations. It has no passenger limit, authorizes operation of inspected vessels (ferries, water taxis, dinner boats)and extends offshore range to 200 miles. The tonnage (25, 50, or 100 GT) indicates the maximum vessel size you're licensed to operate.

The OUPV (6-Pack) limits you to 6 paying passengers on uninspected vessels up to 100 miles offshore. The Master license removes the passenger cap, permits operation of inspected passenger vessels (like ferries and water taxis), and extends your offshore range to 200 miles. The Master also requires more sea service days and is only available to U.S. citizens and Lawful Permanent Residents.

No. The USCG does not require an OUPV as a prerequisite. If you meet the sea service and eligibility requirements for a Master license, you can apply directly. Many experienced boaters skip the OUPV entirely.

An uninspected vessel has not undergone a formal USCG inspection process and does not hold a Certificate of Inspection (CG-841). Most recreational and small commercial vessels are uninspected. Vessels carrying more than six passengers for hire must meet additional construction and safety standards and are subject to periodic USCG inspection.
