What is the OUPV Six-Pack captain license?
OUPV stands for Operator of Uninspected Passenger Vessels. It is the Coast Guard endorsement commonly used by charter-fishing guides, harbor-tour operators, and other small-vessel operators who carry up to six passengers for hire on an uninspected vessel. Route authority depends on whether the credential is issued for Near Coastal, Great Lakes/Inland, or Inland service.
How many questions are on the OUPV exam?
The current OUPV examination structure is 160 questions total across four modules: 50 Rules of the Road questions, 50 Deck General/Safety questions, 50 Navigation General questions, and 10 Chart Plot questions. Great Lakes/Inland and Inland candidates take route-appropriate versions of the Rules and Navigation General modules, but the overall question count remains 160.
