- ONC07 is four modules, 160 questions total, all multiple choice with four options each.
- Rules of the Road and Chart Plot require a 90 passing score; the other two modules require 70.
- Total fees under 46 CFR 10.219 Table 1 are $240: $100 evaluation, $95 examination, $45 issuance, paid via Pay.gov.
- You get two retests within three months for one or two failed modules; three-plus failures mean a full re-exam with a new fee.
The Basics: Governing Body, Exam Code, Format
The National Operator of Uninspected Passenger Vessel Less Than 100 GRT credential is governed by the United States Coast Guard's National Maritime Center (NMC). Testing happens at Coast Guard Regional Examination Centers or through USCG-approved course providers that offer testing in lieu of examination. The exam code that this site and cheat sheet is built around is ONC07, the OUPV Near Coastal route, which is the highest-volume path candidates take. If you're pursuing the Great Lakes and Inland version instead, that's exam code GLI07, which adds a separate Q300 Inland Rules module; Limited OUPV is coded GLI08. This sheet focuses on ONC07 specifics.
For a fuller explanation of what this credential actually is and how it differs from similarly named offshore licenses, see What Is OUPV? and OUPV Meaning. If you landed here wondering what the letters even represent, What Does OUPV Stand For? covers that groundwork.
Fee Breakdown and Payment Mechanics
Fees for an original lower-level officer endorsement follow 46 CFR 10.219 Table 1 and break into three line items:
| Fee Component | Amount |
|---|---|
| Evaluation | $100 |
| Examination | $95 |
| Issuance | $45 |
| Total | $240 |
All of this is paid through Pay.gov before your first module begins. For a line-by-line look at how these fees interact with sea-service documentation, medical exams, and TWIC costs, read OUPV Certification Cost 2026: Complete Pricing Breakdown.
The Four Modules at a Glance
ONC07 splits into four separately graded modules. Three of them carry 50 questions each and together account for roughly 94 percent of everything you'll answer, so weighting your review toward those three is not optional - it's arithmetic.
Domain 1: Q100 Rules of the Road: Inland and International (31%)
Closed book, no references permitted at all. This is the only module tested with zero reference materials, which makes it the highest-stakes memorization module on the exam.
- Lights, shapes, and sound signals for both Inland and International rules
- Steering and sailing rules, including crossing, meeting, and overtaking situations
- Distress signals and narrow channel/fairway rules
Domain 2: Q170 Deck General/Safety (31%)
Covers vessel safety equipment, stability basics, firefighting, and regulatory knowledge relevant to small passenger vessel operation.
- Fire prevention, detection, and extinguishing procedures
- Stability, hull, and deck equipment fundamentals
- Emergency procedures and safety regulations for uninspected passenger vessels
Domain 3: Q171 Navigation General: Near Coastal (31%)
Broad navigation knowledge module that pairs conceptually with the plotting work tested separately in Domain 4.
- Aids to navigation, buoyage systems, and chart symbols
- Tides, currents, and their practical effect on near-coastal transit
- Basic navigation rules, terminology, and publications
Domain 4: Q172 Navigation Problems: Chart Plot (6%)
Only 6% of the exam by weight, but it carries the tightest passing threshold on the entire test.
- Plotting positions, courses, and distances on training charts
- Working with maneuvering boards and plotting sheets
- Precision with dividers, triangles, and a nautical slide rule
For a deeper walkthrough of each domain's testable content and how examiners typically phrase questions, see OUPV Exam Domains 2026: Complete Guide to All 4 Content Areas.
Passing Scores and Margin for Error
Passing thresholds are not uniform across modules, and this is one of the most misunderstood parts of the exam:
- Rules of the Road: 90 passing score - you can miss only five questions
- Chart Plot: 90 passing score - you can miss only one question
- Deck General/Safety: 70 passing score
- Navigation General: 70 passing score
Key Takeaway
Chart Plot's small question count combined with its 90 passing score means a single careless plotting error can fail the module. Treat it with the same seriousness as Rules of the Road, not as an afterthought because it's only 6% of the exam.
For the full context on how these thresholds were set and what "passing" actually means at the module level, read OUPV Passing Score 2026: Exactly What You Need to Pass.
Scheduling Rules You Cannot Ignore
Each module carries a three-and-a-half hour time limit. Beyond that, the scheduling structure has specific requirements that trip up unprepared candidates:
- A minimum of two modules must be completed per day
- All four modules must be completed on consecutive business days within the same week
- Everything must fall inside a 90-day examination cycle
- Your Approval to Test carries a one-year validity window
This isn't a "test whenever you feel ready" credential - once your window opens, the clock is running on multiple levels simultaneously. Full testing-window logistics, deadlines, and how to plan around them are covered in OUPV Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
What References Are Allowed (and Where)
Reference policy varies by module, and mixing this up is a common, avoidable mistake:
- Rules of the Road: closed book, no references of any kind
- Other deck modules: REC-supplied references only, including Light List and Coast Pilot reprints, Tide Tables and Tidal Current Tables, training charts, and maneuvering boards/plotting sheets
- Personal tools allowed: your own dividers, triangles, nautical slide rule, and a non-programmable calculator
Prerequisites Checklist
Under 46 CFR 11.467 and 11.201, before you can sit for ONC07 you need:
- Minimum age of 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 route
- A valid TWIC
- A CG-719K medical certificate
- A DOT drug test on CG-719P
- Current CPR and first aid certification
For a step-by-step breakdown of how to document each of these and avoid application delays, see OUPV Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Retest Policy If You Fail a Module
Under 46 CFR 11.217, if you fail one or two modules, you're allowed two retests within three months. But if you fail three or more modules, that triggers a complete re-examination - meaning you start over and pay a new examination fee. This threshold makes it worth over-preparing for your weakest module rather than gambling on a marginal pass across all four.
Credential Validity and Renewal
Once issued, the credential is a Merchant Mariner Credential valid for five years. Renewal happens either through qualifying sea service or through an open-book renewal exercise - Q173 for the near coastal route, or Q359 for Great Lakes and Inland. Knowing this in advance helps you plan long-term if you're weighing whether the credential fits your career path; see Is the OUPV Certification Worth It? Complete ROI Analysis 2026 and OUPV Jobs for how the credential gets used after issuance.
A One-Week Review Plan Using This Sheet
Because all four modules must be completed on consecutive business days within a single week, your final review should mirror that same compressed structure rather than a loose multi-month plan. Use the weighting from the domains above to decide where your review hours go.
Rules of the Road Deep Review
- Drill lights, shapes, sound signals, and steering rules with no notes, since the actual module is closed book
- Target near-zero errors given the 90 passing score and five-question miss limit
Deck General/Safety and Navigation General
- Review firefighting, stability, and safety regulation material for Q170
- Cover aids to navigation, buoyage, tides and currents for Q171
Chart Plot Precision Practice
- Practice with maneuvering boards, plotting sheets, dividers, and a nautical slide rule
- Remember only one missed question is tolerated under the 90 passing score
For structured guidance on pacing this kind of compressed review and avoiding burnout across back-to-back testing days, see OUPV Study Guide 2026: How to Pass on Your First Attempt. If you want a candid assessment of where most candidates actually struggle, How Hard Is the OUPV Exam? Complete Difficulty Guide 2026 breaks that down module by module, and OUPV Pass Rate 2026: What the Data Shows puts the difficulty question in broader context.
