An OUPV (Operator of Uninspected Passenger Vessels) license - commonly called the Six-Pack - allows you to carry up to six paying passengers on an uninspected vessel. If you need to carry more than six passengers or operate an inspected vessel, compare this with the Master captain’s license.
This license is commonly used for fishing charters, sightseeing trips, and other small passenger operations where you are being paid to operate the vessel.
