Everything you need to know before walking into the exam — 4 sections, passing thresholds, prerequisites, study hours, and what to bring.
The OUPV exam is administered by the National Maritime Center (NMC) at Regional Exam Centers throughout the United States. OUPV stands for Operator of Uninspected Passenger Vessel — the federal license that allows you to carry up to six paying passengers for hire on any waters.
The exam consists of four sections, each taken separately. No required classroom course exists — candidates may self-study and schedule their exam directly with a Regional Exam Center. Sections can typically be taken on consecutive days or in a single sitting depending on the center.

| Section | Questions | Pass Score | References | Difficulty |
|---|---|---|---|---|
| 1 — Rules of the Road | 50 | 90% — 45/50 | None | Hardest |

| 4 — Chart Plotting | 10 | 90% — 9/10 | Open-book (chart + tools) | Learnable |
Covers fire extinguisher classes and ratings, personal flotation devices (PFDs), vessel stability, distress signals, and general seamanship. Fire extinguisher questions appear on almost every exam.
Covers tide and current tables, weather interpretation, basic celestial navigation concepts, buoyage systems, and aids to navigation. Requires understanding how to read tide tables and interpret weather data.
Must be memorized — no references allowed. Highest failure rate of any section.
Fire extinguisher classes, PFD types, stability basics. Broad coverage; study the official question bank.
Tides, weather, celestial fundamentals. Heavy use of tide tables and buoyage systems.
Open-book and highly learnable. Hands-on practice with parallel rulers and dividers pays off fast.
You must submit a complete application to the NMC before scheduling your exam. These requirements must be met or in progress.
Minimum 360 days aboard a vessel. At least 90 days must be on near-coastal (offshore) waters. Days are self-certified on a sea service form signed by your supervisor or vessel owner.
Transportation Worker Identification Credential issued by TSA. Required for all merchant mariners. Apply through TSA enrollment centers. Processing can take 4–6 weeks.
Medical certificate completed by a licensed physician. Covers vision, hearing, and general fitness. The form is free to download from the NMC website.
DOT-compliant 5-panel drug screen from an approved testing facility. Results must be submitted with your application. Cost is typically $40–$80.
Current First Aid and CPR certification, both within 1 year of application. American Red Cross and American Heart Association courses are widely accepted.
Federal application fee paid to the NMC. Check the current NMC fee schedule as amounts change periodically. Payment is made online through the Mariner Credentials portal.
2 Forms of ID
Government-issued photo ID (driver's license, passport) plus one secondary ID. Your name must match your NMC application exactly.
Parallel Rulers or Course Plotter
Required for Chart Plotting. Parallel rulers or a Douglas protractor/course plotter — both are accepted. Practice with what you bring.
Dividers
For measuring distances on the chart. Bring a standard set of navigational dividers. Compass dividers work well.
Pencil
Non-mechanical pencil recommended. You will be drawing on the chart. Bring a spare.
Practice Chart
NOAA Chart 12221 (or equivalent training chart) is typically provided by the test center. Confirm with your specific Regional Exam Center in advance.
Section 1 is the most time-intensive and has the highest failure rate. Starting here means you build the hardest material first and can identify gaps early.
Only 10 questions but 90% passing required. The question types are limited and highly repeatable. A few hours of hands-on plotting practice can lock in 9 or 10 correct answers.
The NMC draws directly from the published question bank. Practice with the actual question stems and answer choices — not paraphrased versions. Exact wording matters.
Fire extinguisher classes (A, B, C, D) and ratings (I, II, III, V) appear on nearly every exam. PFD types and stability basics are also heavily tested. Don't assume you know it.
Each section has a time limit. Running timed practice sessions reveals which topics slow you down and builds confidence for the real test environment.
Many Rules of the Road questions specify whether you are on inland or international waters. The rules differ on whistle signals, flashing lights, and the Constrained by Draft concept.
Submit your complete application package
Once all four sections are passed, submit your exam results with your full application (sea service, physical, drug test, CPR, TWIC, fee) to the NMC through the Merchant Mariner Credentials portal.
NMC review and processing
Processing times vary. The NMC publishes current processing timelines on their website. Complete, correct applications process faster. Expect 4–10 weeks under normal conditions.
License issuance
Your Merchant Mariner Credential (MMC) is mailed to your address on file. The OUPV endorsement will appear on your MMC credential card. It is valid for 5 years and renewable.
The NMC exam uses exact question stems from the published USCG question bank. If you practice with questions that have been rewritten or simplified, you may not recognize the actual exam phrasing. Always use the real question bank format.
Many Rules of the Road questions hinge on whether the scenario is inland or international waters. Candidates who study only the general rule without memorizing the differences routinely miss 3–5 questions on Section 1 — enough to fail at the 90% threshold.
Chart Plotting is learnable but requires physical practice with real tools on a real chart. Reading about parallel rulers is not the same as using them under exam conditions. Even 3–4 timed plotting sessions significantly improves accuracy and speed.
The OUPV exam is a four-section written test administered by the National Maritime Center (NMC) at Regional Exam Centers across the United States. OUPV stands for Operator of Uninspected Passenger Vessel — commonly called a 6-pack license because it allows you to carry up to six paying passengers. The exam covers Rules of the Road, Deck General & Safety, Navigation General, and Chart Plotting. There is no required classroom course; candidates may self-study.
Most candidates need 85–110 total study hours spread across the four sections. Rules of the Road requires the most time — 30–40 hours — because it must be memorized with no reference materials allowed and has a 90% passing threshold. Chart Plotting takes 15–20 hours but is highly learnable with hands-on practice. Deck General and Navigation General each take 20–25 hours. Dedicated daily study over 8–12 weeks is a common schedule.
Yes. The NMC does not require any classroom course for the OUPV license. Many candidates pass by self-studying with the official USCG question bank, a chart plotting practice kit, and online practice tools. The most important self-study priority is Rules of the Road, which has the highest failure rate and requires pure memorization. Practice tests using the actual question bank format are the most effective preparation method.
