How do the OUPV vocabulary games work?
There are 4 games built on 19 OUPV terms. In Guess the Term, a clue describes one term and you have six tries to spell it, with green, yellow and gray letters showing how close you are. In Term Match, six terms appear as colored tiles; swap neighbors to line up three or more of the same term, and each match shows what the term means. In Term Pairs, twelve face-down cards hide six pairs of terms; flip two at a time to find each pair, and every pair you find shows what the term means. In Term Search, five terms hide in a grid of letters, reading across, down or diagonally; drag across a term to circle it, and each term you find shows what it means.
Where do the OUPV terms come from?
OpenExamPrep researched each term from the U.S. Coast Guard National Maritime Center (NMC) / Regional Examination Centers (RECs) content outline and primary sources, listed under Sources on this page. The game is independent study material, not an official exam resource.
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.
