What OUPV Actually Stands For
OUPV stands for National Operator of Uninspected Passenger Vessel Less Than 100 GRT. Every word in that phrase matters to the United States Coast Guard's National Maritime Center (NMC), which governs the credential. "Uninspected passenger vessel" refers to a vessel that carries passengers for hire but has not gone through the Coast Guard's formal inspection process required of larger commercial ships. "Less than 100 GRT" (gross register tonnage) caps the size of vessel this license authorizes an operator to run. Put together, the acronym describes a specific, narrowly defined authority to operate smaller passenger vessels - not a general boating license, and not an unrelated credential that happens to share the same four letters.

The Exam Code Behind the Acronym: ONC07
The National Maritime Center doesn't administer "the OUPV exam" as one generic test - it assigns exam codes to specific routes. This site is built around ONC07, the OUPV Near Coastal route, which is the highest-volume version candidates pursue. Two related codes exist under the same acronym family:
- ONC07 - OUPV Near Coastal (the focus of this site)
- GLI07 - Great Lakes and Inland version, which adds a separate Q300 Inland Rules module
- GLI08 - Limited OUPV
Understanding which code applies to you matters before you register, because the module lineup differs. For a full breakdown of how these routes differ and which one fits your operating waters, see OUPV Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Four Modules That Test the "OUPV" Concept
ONC07 is divided into four separately graded modules, all multiple choice with four answer options, totaling 160 questions. Each module carries its own passing threshold, and three of the four modules - the 50-question ones - together account for roughly 94 percent of all questions on the exam.
Domain 1: Q100 Rules of the Road: Inland and International (31%)
Closed book, no references permitted. This module requires memorization of navigation lights, sound signals, and right-of-way rules under both Inland and International regimes.
- 50 questions, passing score of 90 - you can miss only five questions
- No calculator, chart, or reference material allowed during this module
Domain 2: Q170 Deck General/Safety (31%)
Covers vessel stability, firefighting, damage control, and general safety procedures aboard uninspected passenger vessels.
- 50 questions, passing score of 70
- REC-supplied references allowed for this module
Domain 3: Q171 Navigation General: Near Coastal (31%)
Tests chart reading, aids to navigation, tides and currents, and near-coastal piloting knowledge.
- 50 questions, passing score of 70
- Candidates may use Light List and Coast Pilot reprints, Tide Tables, and Tidal Current Tables
Domain 4: Q172 Navigation Problems: Chart Plot (6%)
The smallest module by question count but with the strictest passing score.
- 10 questions, passing score of 90 - only one miss allowed
- Candidates may use training charts, maneuvering boards, plotting sheets, dividers, triangles, a nautical slide rule, and a non-programmable calculator

And if you're still trying to gauge how tough this format is compared to what you expected, How Hard Is the OUPV Exam? Complete Difficulty Guide 2026 breaks down the exact pass thresholds against real question counts.
Key Takeaway
Rules of the Road and Chart Plot both require a 90% passing score - memorize these two modules first since they leave the smallest margin for error.
Who Actually Holds This Credential
The National Operator of Uninspected Passenger Vessel Less Than 100 GRT credential is issued as a Merchant Mariner Credential valid for five years. It authorizes an individual to operate uninspected passenger vessels carrying paying passengers, provided the vessel stays under 100 GRT. Employers who hire people holding this credential typically operate:
- Charter fishing boats
- Small sightseeing or excursion vessels
- Sailing charters and day-sail operations
- Water taxi and small tour boat services on near-coastal or inland/Great Lakes waters
To even sit for the exam, candidates must meet prerequisites under 46 CFR 11.467 and 11.201: minimum age 18, 360 days of sea service accrued since age 16 with at least 90 days within the preceding three years, and 90 days on ocean or near-coastal waters for the near-coastal route. Candidates also need a TWIC card, a CG-719K medical certificate, a DOT drug test on CG-719P, and current CPR and first aid documentation. The full eligibility checklist, including how sea service days are counted, is detailed in OUPV Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Registration and Fee Mechanics
Examinations for this credential are administered at Coast Guard Regional Examination Centers or through USCG-approved course providers testing in lieu of examination. Fees follow 46 CFR 10.219 Table 1 for an original lower-level officer endorsement, and they're paid through Pay.gov before the first module begins.
| Fee Component | Amount |
|---|---|
| Evaluation | $100 |
| Examination | $95 |
| Issuance | $45 |
| Total | $240 |
A candidate's Approval to Test is valid for one year, and once testing begins, all four modules must fall inside a 90-day examination cycle. Scheduling gets specific: a minimum of two modules must be completed per day, and all modules must be finished on consecutive business days within the same week. That means you can't spread ONC07 across separate weekends - once you start, the clock runs tight. Full scheduling logistics, including how to request an Approval to Test window, are covered in OUPV Exam Dates 2026: Testing Windows, Deadlines & Scheduling, and a line-item cost breakdown lives at OUPV Certification Cost 2026: Complete Pricing Breakdown.
Renewal happens every five years, either through qualifying service or an open-book renewal exercise: Q173 for the near-coastal route and Q359 for Great Lakes and Inland. Knowing this upfront helps you plan sea time strategically rather than scrambling near the five-year mark.
Mapping Your Prep to the Acronym's Domains
Because "OUPV" is really shorthand for four distinct graded modules, your study plan should mirror that structure rather than treat the exam as one undifferentiated block of maritime trivia. A simple way to sequence preparation:
Rules of the Road (Q100)
- Drill navigation lights and sound signals daily since this module is closed book with a 90% passing bar
- Use flashcard repetition - no references will be allowed on test day, so build recall now
Deck General/Safety (Q170) and Navigation General (Q171)
- Study these together since both require a 70% passing score and both allow REC-supplied references
- Practice reading Light List and Coast Pilot excerpts so reference lookup feels fast on exam day
Chart Plot (Q172)
- Practice plotting with dividers, triangles, and a nautical slide rule until it's automatic - only 10 questions but a 90% passing score means one miss is your ceiling
- Time yourself against the three-and-a-half hour module limit
Full Simulation
- Run all four modules back-to-back to mirror the consecutive-business-day requirement
- Review missed questions by domain, not just overall score
For a more granular week-by-week plan with practice question targets, see OUPV Study Guide 2026: How to Pass on Your First Attempt. Once you understand exactly what each module demands numerically, OUPV Passing Score 2026: Exactly What You Need to Pass lays out the math on how many questions you can afford to miss in each domain. You can also review outcome trends without relying on invented figures at OUPV Pass Rate 2026: What the Data Shows.
Running timed practice sessions on our practice test platform before you commit to an Approval to Test window is the most reliable way to confirm you're ready for the 90%/70% split across all four modules. Many candidates also keep a condensed reference nearby - the OUPV Cheat Sheet 2026: One-Page Review of Must-Know Facts is built for exactly that kind of last-week review.
Key Takeaway
Study the two 90%-threshold modules - Rules of the Road and Chart Plot - earliest and most intensively, since they offer the smallest margin for error.
