Eligibility Snapshot: What You Need Before You Apply
The National Operator of Uninspected Passenger Vessel Less Than 100 GRT (OUPV) credential is issued by the U.S. Coast Guard National Maritime Center (NMC), and every prerequisite you need to satisfy traces back to two regulatory sections: 46 CFR 11.467 for near coastal service requirements and 46 CFR 11.201 for the general documentation package. Before you ever sit for a module at a Coast Guard Regional Examination Center or through an approved course provider testing in lieu of examination, you need to have your age, sea service, medical clearance, and background documentation squared away.
This is different from simply "studying hard." A candidate can know every rule in the Navigation Rules cold and still be turned away from testing if their sea service log doesn't add up or their TWIC has lapsed. If you're still deciding whether this credential fits your career goals at all, it's worth reading Is the OUPV Certification Worth It? Complete ROI Analysis 2026 before you invest time collecting paperwork.
Age, Sea Service & the 46 CFR 11.467 Requirements
The core eligibility rule is straightforward on paper but detailed in practice:
- Minimum age: 18 years old at the time of application.
- Total sea service: 360 days accrued since age 16.
- Recency requirement: at least 90 of those days must fall within the three years immediately preceding your application.
- Route-specific waters: for the near coastal route (the ONC07 exam this site is built around), 90 of your total days must have been served on ocean or near-coastal waters.
Sea service doesn't need to be one continuous stretch. Many candidates accumulate it across multiple vessels, seasons, or employers, but every day needs to be documented in a way the NMC will accept - typically through vessel logs, employer letters, or a sea service form that lists dates, vessel name, route, and duties. Sloppy or incomplete logs are one of the most common reasons applications bounce back for correction.
Sea Service Documentation Checklist
Before submitting your application, confirm each entry includes:
- Exact dates aboard (not just "summer 2024")
- Vessel name and official number
- Route or waters operated (ocean, near coastal, inland)
- Your position and duties aboard
- A verifying signature from the vessel owner, master, or employer
Required Documentation: TWIC, Medical, Drug Test & CPR
Beyond sea service, four supporting credentials round out your application package:
- TWIC (Transportation Worker Identification Credential): required before you can be issued the merchant mariner credential.
- CG-719K medical certificate: a physical exam confirming you meet the physical and medical standards for mariner duty.
- CG-719P drug test: a DOT-compliant drug test result submitted on the designated form.
- Current CPR and first aid: proof of an active certification, not expired at the time of application.
None of these substitute for exam preparation, but all of them are gating items - the NMC will not issue your Approval to Test without them on file. Build in lead time for scheduling a CG-719K physical and a drug screen, since both typically require an appointment rather than same-day processing.
Key Takeaway
Start your TWIC application and CG-719K physical the same week you begin studying. These have their own processing timelines that run independently of your exam prep schedule.
Fees, Pay.gov & the Approval to Test Cycle
OUPV fees follow the 46 CFR 10.219 Table 1 schedule for an original lower-level officer endorsement, and they total $240, broken into three separately assessed charges:
- $100 evaluation fee
- $95 examination fee
- $45 issuance fee
All three are paid through Pay.gov before your first module, not spread out over the testing week. For a complete breakdown of how these fees compare to other costs candidates often overlook - course tuition, medical exam costs, TWIC renewal - see OUPV Certification Cost 2026: Complete Pricing Breakdown.
Once your evaluation clears, the NMC issues an Approval to Test that's valid for one year. Within that window, you have a 90-day examination cycle to complete testing once you begin. Two module completions per day is the minimum pace, and all modules must be finished on consecutive business days within the same testing week - you can't spread the four modules across separate weeks or take a long break mid-cycle. Scheduling logistics, including how testing weeks are structured at Regional Examination Centers, are covered in OUPV Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
The Four ONC07 Modules You Must Pass
ONC07, the OUPV Near Coastal exam code this site is built around, is the highest-volume route to the credential. It consists of four separately graded modules totaling 160 multiple-choice questions, each with four answer options:
Q100 Rules of the Road: Inland and International - 31%
50 questions. Closed book with no references permitted at all. This is the only module tested without any allowed materials, which makes memorization non-negotiable.
- Requires a 90 passing score - you can miss only five questions
Q170 Deck General/Safety - 31%
50 questions covering safety equipment, stability basics, and general deck operations. Passing score is 70.
Q171 Navigation General: Near Coastal - 31%
50 questions on navigation principles, aids to navigation, and near-coastal piloting concepts. Passing score is 70.
Q172 Navigation Problems: Chart Plot - 6%
The smallest module by question count but one of the two modules requiring a 90 passing score, meaning only one missed question is tolerated.
Notice that the three 50-item modules - Rules of the Road, Deck General/Safety, and Navigation General - together account for roughly 94 percent of all questions on the exam, so your study time should weight accordingly rather than being split evenly across all four. For a full topic-by-topic breakdown of what each domain actually tests, read OUPV Exam Domains 2026: Complete Guide to All 4 Content Areas.
Each module carries a three-and-a-half hour time limit. Outside of Rules of the Road, you're permitted REC-supplied references: Light List and Coast Pilot reprints, Tide Tables and Tidal Current Tables, training charts, maneuvering boards, and plotting sheets. You may also bring your own dividers, triangles, nautical slide rule, and a non-programmable calculator. Knowing which module allows which tool in advance saves confusion on test day.
Passing Scores & the Retest Rules
Passing thresholds vary by module, and the math behind them matters more than it looks:
| Module | Questions | Passing Score | Missable Questions |
|---|---|---|---|
| Rules of the Road (Q100) | 50 | 90 | 5 |
| Deck General/Safety (Q170) | 50 | 70 | 15 |
| Navigation General (Q171) | 50 | 70 | 15 |
| Chart Plot (Q172) | 10 | 90 | 1 |
For an exact walkthrough of how these thresholds are calculated and why the 90 percent modules deserve disproportionate attention, see OUPV Passing Score 2026: Exactly What You Need to Pass. If you want a candid look at what makes this exam genuinely difficult beyond the raw numbers, How Hard Is the OUPV Exam? Complete Difficulty Guide 2026 digs into the format and pacing pressure.
Under 46 CFR 11.217, if you fail one or two modules, you get two retest attempts within three months without paying a new examination fee. Fail three or more modules, however, and the rule resets you entirely - you must complete a full re-examination and pay a new examination fee. That's a strong incentive to treat the first attempt seriously rather than planning to "learn from the retest."
Key Takeaway
Because three or more module failures trigger a full re-exam and a new fee, it is cheaper and faster to over-prepare on Rules of the Road and Chart Plot than to gamble on a retest.
Choosing Your Route: ONC07, GLI07 or GLI08
Not every candidate takes the same version of the exam. Three exam codes exist under the OUPV umbrella:
- ONC07 (Near Coastal): the highest-volume route and the one this site is built around, requiring 90 days on ocean or near-coastal waters.
- GLI07 (Great Lakes and Inland): adds a separate Q300 Inland Rules module on top of the standard structure.
- GLI08 (Limited OUPV): a more restricted operating scope.
Your choice depends entirely on where you intend to operate and where your sea service was earned. If most of your logged days were on inland waters rather than ocean or near-coastal routes, GLI07 may be the more realistic and defensible path rather than trying to stretch near-coastal eligibility.
Sequencing Your Prep Around the Requirements
Once your prerequisites are locked in - sea service documented, TWIC in hand, medical and drug test cleared - your remaining job is to sequence study time against the exam's own structure, not a generic study calendar. Given that Rules of the Road and Chart Plot both demand a 90 passing score with almost no margin for error, they deserve early and repeated attention rather than being crammed at the end.
Rules of the Road foundation
- Build closed-book recall since no references are allowed on this module
- Drill lights, shapes, sound signals, and steering/sailing rules daily
Deck General/Safety and Navigation General
- These two 50-question, 70-passing modules carry equal weight - split time evenly
- Practice using only REC-supplied references so you're comfortable with the actual test-day toolkit
Chart Plot precision
- Only 10 questions but a 90 passing score means one wrong answer is the ceiling
- Practice with maneuvering boards, plotting sheets, dividers, and triangles under timed conditions
Full timed run-throughs
- Simulate the three-and-a-half hour limit per module
- Review weak spots identified in earlier weeks before scheduling your testing week
For a more detailed day-by-day breakdown of this kind of preparation, OUPV Study Guide 2026: How to Pass on Your First Attempt expands on techniques specific to each module. Running full-length practice sessions on our OUPV practice test platform before test week is one of the most direct ways to confirm you're ready for the actual pacing and question style.
After You Qualify: Who Hires OUPV Holders
Once issued, the OUPV credential comes as a Merchant Mariner Credential valid for five years, renewable either through qualifying service or the open-book renewal exercise - Q173 for near coastal holders, Q359 for Great Lakes and Inland. Employers hiring for uninspected passenger vessels under 100 gross registered tons include charter fishing operators, small tour and sightseeing boat companies, sailing charter businesses, and dive charter operations. Because the credential caps at vessels carrying a limited number of passengers on uninspected boats, it's commonly the entry credential mariners use before pursuing higher-tonnage endorsements.
If you're weighing how this credential translates into actual job prospects and pay, OUPV Jobs and OUPV Salary Guide 2026: Complete Earnings Analysis go into more depth on the employer landscape than requirements alone can cover. And if you're still confirming the fundamentals of what this credential actually authorizes you to do, What Is OUPV? is a useful starting point before you commit to the prerequisite process outlined above.
Frequently Asked Questions
You need 360 days total, accrued since age 16, with at least 90 of those days within the preceding three years. For the near coastal route, 90 of your total days must have been on ocean or near-coastal waters.
Fees total $240 under 46 CFR 10.219 Table 1: $100 for evaluation, $95 for examination, and $45 for issuance. All three are paid through Pay.gov before your first module.
Rules of the Road is closed book with no references allowed. The other three modules permit REC-supplied materials like Light List and Coast Pilot reprints, Tide Tables, training charts, and your own dividers, triangles, nautical slide rule, and non-programmable calculator.
If you fail one or two modules, you get two retest attempts within three months at no new examination fee. Failing three or more modules requires a complete re-examination and a new fee.
One year. Within that window, once you begin testing you're inside a 90-day examination cycle and must complete a minimum of two modules per day on consecutive business days within the same testing week.
Meeting every prerequisite before you schedule a testing week is what separates a smooth OUPV application from a delayed one. Once your sea service, TWIC, medical, and drug test documentation are in order, the remaining work is entirely about module-specific preparation - and that's where a realistic practice environment like OUPV Exam Prep's practice tests pays off most directly.
