- The National OUPV credential (exam code ONC07) qualifies you to operate uninspected passenger vessels under 100 GRT carrying up to six passengers for hire.
- ONC07 has four graded modules totaling 160 questions; three of the four modules carry 50 questions each, roughly 94% of the exam.
- Passing requires 90% on Rules of the Road and Chart Plot, and 70% on Deck General/Safety and Navigation General.
- Total original endorsement fees run $240 ($100 evaluation, $95 examination, $45 issuance) paid through Pay.gov before your first module.
What OUPV Jobs Actually Look Like
The National Operator of Uninspected Passenger Vessel Less Than 100 GRT (OUPV) credential exists for one purpose: it authorizes the holder to serve as master or operator of an uninspected passenger vessel under 100 gross registered tons that carries paying passengers, typically up to six under the "six-pack" limit associated with this class of vessel. That single authorization opens a range of on-the-water roles where someone needs to be legally in command of a small passenger-carrying boat.
In practice, day-to-day work under this credential means running the boat, managing passenger safety, navigating, communicating with dispatch or shore, and handling the paperwork and compliance obligations that come with carrying the public for hire. It is not a desk job and it is not a shoreside administrative role - it is hands-on vessel operation, which is exactly what the exam modules are built to test.
Who Hires OUPV Credential Holders
Because the credential is tied to uninspected passenger vessels under 100 GRT, hiring generally comes from operators running small passenger boats rather than large inspected vessels. That includes charter operations, guided fishing and tour boats, and other small-vessel businesses that need a legally qualified individual at the helm whenever passengers are aboard for hire. Some mariners hold the credential as a stepping stone within a broader small-vessel career, others hold it because it is the specific authorization their current or intended employer requires for the boats they run.
Because hiring patterns and pay vary widely by region, vessel type, and employer, this article intentionally does not manufacture numbers. If you want a breakdown of how compensation is typically discussed for this credential, see the OUPV Salary Guide 2026: Complete Earnings Analysis. If you're still deciding whether the time and fees are worth it for your situation, the Is the OUPV Certification Worth It? Complete ROI Analysis 2026 article walks through that decision in more depth.
Key Takeaway
Employers hiring for this credential care about one thing first: whether you can legally operate their specific vessel type on their specific waters. Confirm the near-coastal vs. Great Lakes/Inland distinction before assuming a job posting matches ONC07.
The Exam That Stands Between You and These Jobs
Every OUPV job ultimately traces back to one gate: passing the National Maritime Center's examination process. The NMC governs the credential, and testing happens either at Coast Guard Regional Examination Centers or through USCG-approved course providers that test in lieu of examination. Fees follow 46 CFR 10.219 Table 1 for an original lower-level officer endorsement - $100 for evaluation, $95 for examination, and $45 for issuance, totaling $240, paid through Pay.gov before your first module begins.
The ONC07 exam itself is four separately graded modules, all multiple choice with four answer options, 160 questions in total:
Domain 1: Q100 Rules of the Road: Inland and International (31%)
Closed book, no references permitted. This is the only module where you cannot use REC-supplied materials, so every rule needs to be memorized cold. Passing score is 90%, meaning you can miss only about five questions across this module.
- Navigation lights, sound signals, and steering/sailing rules for both Inland and International regimes
Domain 2: Q170 Deck General/Safety (31%)
Covers vessel safety equipment, emergency procedures, and general deck operations. Passing score is 70%.
- Requires familiarity with safety gear standards relevant to uninspected passenger vessels
Domain 3: Q171 Navigation General: Near Coastal (31%)
Tests navigation knowledge appropriate to near coastal operation. Passing score is 70%, and REC-supplied references such as Light List and Coast Pilot reprints, Tide Tables and Tidal Current Tables are allowed.
- Chart symbols, aids to navigation, tides and currents, and coastal piloting concepts
Domain 4: Q172 Navigation Problems: Chart Plot (6%)
Smaller in question count but demanding in precision - passing score is 90%, so you can miss only about one question. Candidates may use their own dividers, triangles, nautical slide rule, and non-programmable calculator along with training charts, maneuvering boards, and plotting sheets.
- Plotting positions, courses, and fixes accurately under a three-and-a-half hour time limit
Because Rules of the Road, Deck General/Safety, and Navigation General each carry 50 questions, those three modules together account for roughly 94% of everything tested - the Chart Plot module, despite its strict 90% passing threshold, is the smallest by question count. For a full breakdown of how these four areas interact and where to focus your study time, see the OUPV Exam Domains 2026: Complete Guide to All 4 Content Areas. For the exact numeric thresholds explained module by module, check the OUPV Passing Score 2026: Exactly What You Need to Pass guide.
| Route | Exam Code | Notes |
|---|---|---|
| OUPV Near Coastal | ONC07 | Highest-volume route; four modules, 160 questions |
| OUPV Great Lakes and Inland | GLI07 | Adds a separate Q300 Inland Rules module |
| Limited OUPV | GLI08 | Restricted-scope variant of the Great Lakes and Inland route |
Scheduling matters as much as content: each module has a three-and-a-half hour limit, you must complete a minimum of two modules per day, and all four modules must be finished on consecutive business days within the same week, inside a 90-day examination cycle and a one-year Approval to Test validity. Miss that window and you're back to rescheduling. Full testing-window logistics are covered in the OUPV Exam Dates 2026: Testing Windows, Deadlines & Scheduling article.
Sea Service and Paperwork You Need First
You cannot walk into an exam center for this credential without meeting the prerequisites in 46 CFR 11.467 and 11.201 first. These are the same requirements that ultimately determine when you're eligible for OUPV jobs at all:
- Minimum age 18
- 360 days of sea service accrued since age 16, with at least 90 days within the preceding three years
- 90 days specifically on ocean or near-coastal waters for the near-coastal (ONC07) route
- A valid TWIC
- A CG-719K medical certificate
- A DOT drug test completed on CG-719P
- Current CPR and first aid
These prerequisites, combined with the $240 in fees, form the full financial and administrative picture of getting from zero to credentialed. For a complete line-item breakdown, see OUPV Certification Cost 2026: Complete Pricing Breakdown, and for a plain-language walk-through of every eligibility rule, see OUPV Requirements 2026: Eligibility, Prerequisites & How to Qualify.
What You Hold Once You Pass
Passing all four ONC07 modules results in a Merchant Mariner Credential (MMC) valid for five years. Renewal happens either by qualifying service or by completing the open-book renewal exercise - Q173 for the near coastal route, or Q359 for Great Lakes and Inland. That renewal path is worth knowing early, because it affects how you plan sea time and continuing eligibility over the life of the credential, not just at the point of initial hire.
If you're still building context on what this credential is and how it differs from similarly-named credentials, start with What Is OUPV? and OUPV Certification before moving into exam prep specifics.
Scheduling Your Prep Around the Four Modules
Because all four modules must be completed on consecutive business days within the same week, your preparation should mirror the exam's own structure rather than a generic study calendar. The two highest-stakes modules - Rules of the Road (90% passing, closed book, no references) and Chart Plot (90% passing, smallest question count) - deserve disproportionate rehearsal time relative to their share of total questions, since a handful of missed answers on either can fail the module outright.
Rules of the Road
- Drill navigation lights, sound signals, and steering rules until recall is automatic - no references allowed on exam day
Deck General/Safety and Navigation General
- Work through safety equipment standards and near-coastal navigation concepts, practicing with the same REC-supplied reference types you'll have on exam day
Chart Plot
- Practice plotting under the three-and-a-half hour time limit using dividers, triangles, and plotting sheets until accuracy is consistent enough to miss no more than one question
Full Run-Through
- Simulate the consecutive-business-day format, completing at least two modules per day as required
For a structured walk-through of first-attempt strategy, see the OUPV Study Guide 2026: How to Pass on Your First Attempt, and for an honest assessment of where most candidates underestimate the exam, read How Hard Is the OUPV Exam? Complete Difficulty Guide 2026. If you want outcome data rather than opinion, the OUPV Pass Rate 2026: What the Data Shows article and a condensed OUPV Cheat Sheet 2026: One-Page Review of Must-Know Facts are both useful once you've covered the material once. You can also build exam-day timing skills directly with practice tests modeled on the ONC07 format.
Key Takeaway
Don't split study time evenly across four modules. Rules of the Road and Chart Plot carry 90% passing thresholds with zero reference materials or minimal question count margin - prioritize memorization there over the two 70%-threshold modules.
