- ONC07 has four separately graded modules; you must clear each one on its own, not just the total.
- Rules of the Road and Chart Plot require a 90, leaving room for only 5 and 1 missed questions respectively.
- Three 50-question modules make up roughly 94% of all 160 questions on the exam.
- Two retests are allowed within three months for one or two failed modules; a third failure resets the entire exam and fee.
Why "Pass Rate" Isn't a Simple Number for OUPV
The National Maritime Center does not publish a single, unified pass rate for the National Operator of Uninspected Passenger Vessel Less Than 100 GRT (OUPV) credential, and there is no official aggregate figure to quote for 2026. What the available structural data does show is something more useful for a candidate preparing right now: exactly where OUPV candidates are most likely to lose points, and why. Instead of chasing a phantom statistic, this article walks through the module design, scoring thresholds, and retest mechanics built into 46 CFR to show where the real risk sits in the ONC07 exam.
If you haven't yet reviewed the full breakdown of what's tested, the OUPV Exam Domains 2026: Complete Guide to All 4 Content Areas is the companion piece to this one - it explains content, while this article explains the scoring mechanics that determine whether that content knowledge translates into a passing credential.
How ONC07 Is Built: Four Modules, 160 Questions
ONC07 - OUPV Near Coastal, the highest-volume route through the National Maritime Center - is split into four separately graded modules, all multiple choice with four answer options:
- Q100 Rules of the Road: Inland and International - 50 questions
- Q170 Deck General/Safety - 50 questions
- Q171 Navigation General: Near Coastal - 50 questions
- Q172 Navigation Problems: Chart Plot - 10 questions
Each module carries its own three-and-a-half hour limit and is graded independently. That last part matters more than it might seem: a strong score on Chart Plot does nothing to offset a weak score on Rules of the Road. You are not passing "an exam" in the aggregate sense - you are passing four separate gates, each with its own threshold, on the same testing cycle.
Every candidate is testing under a 90-day examination cycle tied to a one-year Approval to Test. For the specifics of scheduling within that window, see OUPV Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
The Passing Scores That Actually Decide Outcomes
This is where the real "pass rate math" lives. The required passing scores are not uniform across modules:
| Module | Questions | Passing Score | Margin for Error |
|---|---|---|---|
| Q100 Rules of the Road | 50 | 90% | Miss no more than 5 |
| Q170 Deck General/Safety | 50 | 70% | Miss up to 15 |
| Q171 Navigation General | 50 | 70% | Miss up to 15 |
| Q172 Chart Plot | 10 | 90% | Miss no more than 1 |
Two modules demand near-perfection. Rules of the Road allows only five missed questions out of fifty, and it's closed book - no references of any kind. Chart Plot is even less forgiving in raw terms: with only ten questions, missing a single plot can fail the module. Deck General/Safety and Navigation General are more forgiving at 70%, but they're also the largest single blocks of content by question count.
For the complete threshold breakdown by module, including how these numbers were derived from 46 CFR, see OUPV Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Treat Rules of the Road and Chart Plot as zero-margin modules in your prep. A candidate who is "pretty good" at Rules of the Road but not excellent is statistically the most likely failure point on the entire exam, given the 90% threshold.
Why Three Modules Carry 94% of the Weight
Rules of the Road, Deck General/Safety, and Navigation General are each 50-question modules. Combined, these three 50-item modules account for roughly 94% of all 160 questions on ONC07. Chart Plot, despite its unforgiving 90% threshold, is only 10 questions - about 6% of the total question volume.
This changes how study time should be allocated. It's tempting to spend disproportionate energy on Chart Plot because of its strict passing score, but the sheer volume of content in the other three domains means broad content mastery matters more than narrow perfection on the smallest module.
Q100 Rules of the Road: Inland and International
Closed book, no references permitted, 90% required. Covers both Inland and International navigation rules - lights, shapes, sound signals, and steering/sailing rules. The zero-reference format means memorization has to be exact, not approximate.
- Highest-stakes module due to the strict threshold
- No REC-supplied references allowed here, unlike other modules
Q170 Deck General/Safety
Broad coverage of vessel safety, stability basics, firefighting, emergency procedures, and general deck operations. At 70%, this module rewards broad familiarity over narrow perfection.
- Largest content pool by topic breadth
- REC-supplied references permitted where applicable
Q171 Navigation General: Near Coastal
Covers piloting, tides, currents, aids to navigation, and chart interpretation for near coastal operations. Reference materials like Light List, Coast Pilot reprints, Tide Tables, and Tidal Current Tables are allowed.
- Reference-heavy module - knowing how to use REC-supplied materials efficiently saves time
- Ties directly into the practical skills tested in Chart Plot
Q172 Navigation Problems: Chart Plot
Only 10 questions but a 90% passing score. Requires accurate use of training charts, maneuvering boards, plotting sheets, dividers, triangles, a nautical slide rule, and a non-programmable calculator.
- Smallest question count, least room for error
- Speed and accuracy with plotting tools matter as much as conceptual knowledge
For a topic-by-topic breakdown of each domain, the OUPV Exam Domains 2026: Complete Guide to All 4 Content Areas goes deeper than this article's scoring-focused view.
What Happens When a Module Is Failed
Under 46 CFR 11.217, the retest structure is generous but not unlimited:
- If one or two modules are failed, two retests are allowed within three months.
- If three or more modules are failed, the candidate must complete a full re-examination and pay a new examination fee.
This threshold - one or two modules versus three or more - is arguably the single most important number in the entire regulatory structure for candidates. It means a bad day on Rules of the Road and a bad day on Chart Plot is still recoverable without starting over financially. But a bad day across three or four modules pushes the candidate back to square one on fees and scheduling.
This is also why module-by-module readiness matters more than an aggregate "I feel ready" assessment. If you can predict which one or two modules are your weak points before test day, you can plan around the retest allowance instead of being surprised by it. The How Hard Is the OUPV Exam? Complete Difficulty Guide 2026 article walks through which modules tend to be hardest based on the reference restrictions and threshold structure.
Fees, Attempts, and the Cost of a Retake
Under 46 CFR 10.219 Table 1, an original lower-level officer endorsement carries a $100 evaluation fee, a $95 examination fee, and a $45 issuance fee, for a total of $240 paid through Pay.gov before the first module begins. That fee structure is a factor in how the retest rule matters: passing three of four modules and retesting the fourth doesn't require paying the full $240 again, but failing three or more modules and needing a complete re-examination does require a new examination fee.
In other words, the financial "penalty" for failure isn't uniform - it scales sharply once you cross from one-or-two failed modules into three-or-more failed modules. That single line in 46 CFR 11.217 is effectively the dividing line between a manageable setback and a costly restart.

The Testing Week Itself Affects Performance
OUPV candidates don't sit for four modules whenever they choose. A minimum of two modules must be completed per day, and all modules must be completed on consecutive business days within the same week. That's a meaningful constraint: it compresses four separately timed exams (each with a three-and-a-half hour limit) into a short, demanding testing window.
This scheduling structure is easy to overlook when studying content, but it has real performance implications. Sitting for two three-and-a-half hour modules on the same day, potentially back to back, means fatigue management is part of exam readiness - not just content mastery. Candidates who plan their strongest and weakest modules around this compressed schedule, rather than treating each module as an isolated event, tend to manage the week more effectively.
A Domain-Ordered Preparation Timeline
Generic study techniques only go so far without being tied to the specific structure above. Given that Rules of the Road demands a 90% with no references, and the other three modules allow REC-supplied materials, the order in which you build competence matters.
Rules of the Road (Q100)
- Build memorization first, since this module is closed book with a 90% threshold
- Drill lights, shapes, sound signals, and steering/sailing rules until recall is automatic
Deck General/Safety and Navigation General (Q170, Q171)
- Cover the broadest content pools, since these two modules make up the bulk of the 160 total questions
- Practice using REC-supplied references like Light List and Tide Tables efficiently under timed conditions
Chart Plot (Q172)
- Focus tool proficiency: dividers, triangles, nautical slide rule, and non-programmable calculator
- Since only one missed question fails this module, run timed plotting drills repeatedly
Full Review and Mock Testing Week
- Simulate the consecutive-day, two-modules-per-day format to build stamina
- Revisit weak areas identified in earlier practice sessions

ONC07 vs. GLI07: Module Differences
Not every OUPV candidate is testing on the same exam code. ONC07 is the Near Coastal route and the highest-volume path, but the Great Lakes and Inland version, GLI07, adds a separate Q300 Inland Rules module. Limited OUPV uses exam code GLI08. Knowing which code you're registered for matters before you build a study plan.
| Feature | ONC07 (Near Coastal) | GLI07 (Great Lakes/Inland) |
|---|---|---|
| Core modules | Q100, Q170, Q171, Q172 | Q100, Q170, Q171, Q172 |
| Additional module | None | Q300 Inland Rules |
| Total questions | 160 | 160 plus Q300 |
| Route volume | Highest-volume route | Lower volume, region-specific |
If you're unsure which route applies to your eligibility, review OUPV Requirements 2026: Eligibility, Prerequisites & How to Qualify, which covers the 360 days of sea service, TWIC, CG-719K medical certificate, and drug testing requirements under 46 CFR 11.467 and 11.201 that apply regardless of exam code.
Who Sits for OUPV and Why the Thresholds Matter to Them
OUPV credential holders typically operate small passenger vessels under 100 gross registered tons - charter fishing boats, small tour operations, and similar six-pack style operations. Because the credential leads directly to paid work on the water, the module thresholds aren't academic; a missed 90% on Rules of the Road delays the ability to legally operate for hire. For context on how this credential translates into employment, see OUPV Jobs and OUPV Salary Guide 2026: Complete Earnings Analysis. Whether the time and fee investment is worthwhile given your career goals is covered in Is the OUPV Certification Worth It? Complete ROI Analysis 2026.
You can also build familiarity with the question format itself by running full-length practice sessions on the main OUPV practice test platform before committing to your official testing week. Repeated exposure to the multiple-choice format under timed conditions on the practice test site is one of the more direct ways to reduce surprises during the real four-module sequence.
Frequently Asked Questions
There is no published aggregate pass rate for ONC07. The most reliable data available to candidates is the module structure itself: passing scores, question counts, and retest rules under 46 CFR.
Rules of the Road is widely considered the most demanding because it is closed book with no references allowed and requires a 90% score, leaving room for only five missed questions out of fifty.
Under 46 CFR 11.217, failing three or more modules requires a complete re-examination and a new examination fee, rather than the two retests within three months allowed for one or two failed modules.
Yes. Unlike Rules of the Road, Chart Plot and the other deck modules allow REC-supplied references such as training charts, maneuvering boards, plotting sheets, and personal tools like dividers, triangles, a nautical slide rule, and a non-programmable calculator.
ONC07 has 160 questions across four separately graded modules: Rules of the Road (50), Deck General/Safety (50), Navigation General (50), and Chart Plot (10).
