- ONC07 has four separately graded modules totaling 160 multiple-choice questions.
- Rules of the Road and Chart Plot require a 90 score; Deck General/Safety and Navigation General require 70.
- Total original endorsement fees run $240, split into $100 evaluation, $95 examination, and $45 issuance under 46 CFR 10.219 Table 1.
What Is OUPV Certification?
OUPV stands for National Operator of Uninspected Passenger Vessel Less Than 100 GRT. It is a United States Coast Guard credential that authorizes a mariner to carry paying passengers - up to six under most uninspected passenger vessel rules - aboard vessels under 100 gross register tons. The credential is not a training class certificate; it is an officer endorsement earned by meeting sea service requirements and passing a proctored, multiple-choice examination administered under Coast Guard regulation.
Because several maritime and non-maritime fields use similar-sounding abbreviations, it's worth being precise: this article covers exactly the National Operator of Uninspected Passenger Vessel Less Than 100 GRT endorsement, its exam structure, its fee schedule, and its renewal path. If you're still sorting out terminology, the companion pieces What Is OUPV? and OUPV Meaning walk through the acronym itself before diving into exam mechanics.
Who Governs OUPV and Where You Test
OUPV is governed by the United States Coast Guard National Maritime Center (NMC). Examinations are administered either at Coast Guard Regional Examination Centers or through USCG-approved course providers offering "testing in lieu of examination," where an approved school delivers the same modules under Coast Guard-sanctioned proctoring.
This site is built specifically around exam code ONC07, the OUPV Near Coastal exam - the highest-volume route among the OUPV family. It's worth noting there are related but distinct versions: the Great Lakes and Inland route uses exam code GLI07 and adds a separate Q300 Inland Rules module, while Limited OUPV uses GLI08. If your route is Great Lakes and Inland rather than Near Coastal, the module count and rules content differ from everything described below.
The Four Modules of the ONC07 Exam
ONC07 is composed of four separately graded modules, all multiple choice with four answer options, totaling 160 questions. Each module carries its own three-and-a-half hour time limit and its own passing threshold - you don't get an averaged score across the exam.
Domain 1: Q100 Rules of the Road: Inland and International (31%)
Covers navigation lights, sound signals, steering and sailing rules, and the differences between Inland and International Rules. This module is closed book with no references permitted, so every rule must be memorized cold.
- 50 questions, 90 required to pass - only about 5 misses allowed
Domain 2: Q170 Deck General/Safety (31%)
Covers vessel stability basics, firefighting, lifesaving equipment, emergency procedures, and general deck safety practices expected of a small passenger vessel operator.
- 50 questions, 70 required to pass
Domain 3: Q171 Navigation General: Near Coastal (31%)
Covers chart symbols, aids to navigation, tides and currents, piloting concepts, and general navigation knowledge specific to near coastal operations.
- 50 questions, 70 required to pass
Domain 4: Q172 Navigation Problems: Chart Plot (6%)
A hands-on plotting module where candidates work actual chart problems using dividers, parallel rules or a nautical slide rule, and plotting sheets.
- 10 questions, 90 required to pass - only 1 miss allowed
Notice that the three 50-item modules - Rules of the Road, Deck General/Safety, and Navigation General - together make up roughly 94 percent of all 160 questions on the exam. Chart Plot is a small module by question count, but its 90-score threshold makes it just as unforgiving as Rules of the Road. For a full breakdown of what's tested inside each domain, see the OUPV Exam Domains 2026: Complete Guide to All 4 Content Areas.
Passing Scores and Question Format
Every question on ONC07 is multiple choice with exactly four answer options - there's no fill-in-the-blank, essay, or simulation component. What makes the exam demanding isn't the question format; it's the split passing standard:
| Module | Questions | Passing Score | Max Misses |
|---|---|---|---|
| Rules of the Road | 50 | 90 | ~5 |
| Deck General/Safety | 50 | 70 | ~15 |
| Navigation General | 50 | 70 | ~15 |
| Chart Plot | 10 | 90 | 1 |
Because Rules of the Road and Chart Plot both require a 90, candidates often underestimate how little margin they have on those two modules while feeling comfortable with the 70-score modules. A full explanation of exactly how these thresholds are calculated lives in the OUPV Passing Score 2026: Exactly What You Need to Pass guide.
Key Takeaway
Treat Rules of the Road and Chart Plot as your two highest-stakes modules - a 90 threshold leaves almost no room for careless errors, even though Chart Plot is only 10 questions.
Prerequisites Before You Sit the Exam
Eligibility for OUPV is defined under 46 CFR 11.467 and 11.201. Before scheduling any exam module, a candidate must document:
- 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 of that sea service on ocean or near-coastal waters for the Near Coastal route specifically
- A valid TWIC
- A CG-719K medical certificate
- A completed DOT drug test on form CG-719P
- Current CPR and first aid certification
These aren't paperwork formalities you handle after the exam - the sea service and medical documentation must be in order before the National Maritime Center will issue an Approval to Test. For the full checklist with source citations, see OUPV Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Registration, Fees, and the 90-Day Cycle
OUPV fees follow 46 CFR 10.219 Table 1 for an original lower-level officer endorsement, paid through Pay.gov before you sit the first module:
- $100 evaluation fee
- $95 examination fee
- $45 issuance fee
- $240 total
Once your Approval to Test is issued, it's valid for one year, and your actual testing sequence runs inside a 90-day examination cycle. Within that cycle, a minimum of two modules must be completed per day, and all four modules must be finished on consecutive business days within the same week. That means you can't casually spread the exam across several unrelated weeks - once you start, you're on a compressed schedule. A detailed cost walkthrough, including how the evaluation, examination, and issuance fees interact, is available at OUPV Certification Cost 2026: Complete Pricing Breakdown, and current scheduling windows are covered in OUPV Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
What References Are (and Aren't) Allowed
Reference policy varies sharply by module. Rules of the Road is closed book - no references of any kind are permitted, so every navigation light configuration, sound signal, and steering rule has to be recalled from memory under time pressure.
The other deck modules allow only REC-supplied references, which typically include:
- Light List and Coast Pilot reprints
- Tide Tables and Tidal Current Tables
- Training charts, maneuvering boards, and plotting sheets
Candidates may also bring their own dividers, triangles, nautical slide rule, and a non-programmable calculator. Knowing which module allows what before test day prevents the common mistake of over-preparing tools for a closed-book module or under-preparing plotting instruments for Chart Plot.
Retesting 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 without starting over. However, if you fail three or more modules, the regulation requires a complete re-examination and a new examination fee - effectively resetting your attempt. This retest structure is one reason the exam feels harder than a simple pass/fail test; a bad day on two modules is recoverable, but a bad day across three is not. The How Hard Is the OUPV Exam? Complete Difficulty Guide 2026 article goes deeper into how the retest rule shapes realistic difficulty, and OUPV Pass Rate 2026: What the Data Shows looks at how candidates fare across attempts.
After You Pass: Validity and Renewal
Once issued, OUPV is part of your Merchant Mariner Credential and is valid for five years. Renewal happens one of two ways: through qualifying sea service, or through an open-book renewal exercise - Q173 for the Near Coastal route or Q359 for Great Lakes and Inland. This renewal option means the credential doesn't force you back through the full four-module original exam every cycle, provided you keep documentation of qualifying service or complete the renewal exercise on schedule.
Who Hires OUPV Credential Holders
OUPV holders typically operate small passenger-carrying vessels under 100 GRT - the kind of operations where a single license authorizes carrying paying passengers for hire. Common employers and settings include:
- Charter fishing and sportfishing operations
- Sightseeing and eco-tour vessel operators
- Dive charter boats
- Sailing charter and small excursion companies
- Water taxi and small ferry services operating uninspected passenger vessels
Because the credential authorizes commanding a vessel rather than just crewing one, it's often a step toward running your own charter operation.

Complete ROI Analysis 2026.
Building a Study Plan Around Domain Weights
The smartest way to allocate study time is to mirror the exam's own structure rather than spread effort evenly. Since Rules of the Road, Deck General/Safety, and Navigation General each carry 50 questions and together make up roughly 94 percent of all questions, they deserve the bulk of your weekly hours, while Chart Plot - only 10 questions but a 90-point threshold - needs focused, deliberate practice rather than broad review.
Rules of the Road
- Drill navigation lights and sound signals daily since this module is closed book with zero references
- Use timed recall drills, not passive reading, given the 90-score requirement
Deck General/Safety and Navigation General
- Work through safety equipment, stability basics, and piloting concepts
- These 70-score modules allow more margin, so prioritize breadth of coverage
Chart Plot Practice
- Repeat full plotting problems with the same tools allowed on test day: dividers, plotting sheets, and a nautical slide rule
- Since only one miss is allowed on this 10-question module, accuracy matters more than speed
A structured, module-by-module walkthrough of this approach - including which questions tend to trip up first-time candidates - is laid out in the OUPV Study Guide 2026: How to Pass on Your First Attempt. When you're ready to test your recall under exam-like conditions, working through timed practice questions on the main practice test site mirrors the four-module, multiple-choice format you'll actually face at a Regional Examination Center.
Key Takeaway
Schedule your heaviest review time on the three 50-question modules first, then shift to dedicated, tool-based practice for Chart Plot in the final stretch before your Approval to Test window opens.
