What "Qualifying" Means for National Master 200 NC
When mariners ask about the requirements for National Master 200 NC (NM2N), they usually mean two different things at once: the administrative eligibility the Coast Guard evaluates, and the examination content they must be ready to pass. This article focuses on the second part and on how the exam structure is organized, because that is where candidates most often misjudge their workload. If you are still orienting yourself, start with What Is NM2N? and What Does NM2N Stand For? before working through the details below.
The key idea is that qualifying is a process with a defined examination route, not a single generic test. The route for the Near Coastal credential is published by the issuing agency, and the modules it contains are public. Understanding that route precisely is the most practical thing you can do before you begin studying.
Who Sets the Rules: The Coast Guard National Maritime Center
The governing body for this credential is the United States Coast Guard National Maritime Center. The NMC publishes examination information for the Oceans or Near Coastal endorsements, including the module headings that make up each route and a deck and engineering examination guide that lists topic matrices by module. The guide that describes the Near Coastal route is the published document tied to regulations effective March 24, 2014, and the current indexed NMC module pages corroborate the same module headings. That means the content structure you study from is stable and publicly documented rather than hidden.
Two practical consequences follow. First, you should treat the NMC as the authority on any question of eligibility, documentation and which modules apply to you personally. Second, you should be cautious about third-party summaries that claim a single overall question count, exam length or passing percentage for the whole credential. The published packet for this route does not establish one overall question count or duration, and it does not publish a current fee schedule or a population-wide pass rate that you can rely on.

The Five-Module Near Coastal Route
The full original route for Near Coastal contains exactly five examination modules. They are issuer-published, and for preparation purposes they are best treated as five unweighted groups of content rather than as a weighted blueprint with percentages. Each is described below in the order used on this site.
Domain 1: Rules of the Road: Inland and International (Q100)
This module covers the navigation rules that govern vessel conduct, both Inland and International. Candidates must be able to apply the rules to situations rather than simply recite them.
- Right-of-way and give-way relationships between vessels
- Lights, shapes and sound signals
- Differences between Inland and International regimes
Domain 2: Deck General (Q150)
Deck General is the broad seamanship and vessel-operations module. It rewards candidates who have practical familiarity with how a deck department functions.
- Vessel handling and general deck operations
- Stability and cargo-related fundamentals
- Maintenance and day-to-day deck responsibilities
Domain 3: Deck Safety (Q151)
Deck Safety concentrates on protecting people, the vessel and the environment. Expect scenario-style thinking tied to emergencies and prevention.
- Firefighting and lifesaving concepts
- Emergency response and drills
- Pollution prevention and safe working practices
Domain 4: Navigation General: Oceans or Near Coastal (Q152)
Q152's official title spans Oceans or Near Coastal. For your purposes it is applied to the Near Coastal route. It is the general navigation knowledge module, distinct from the chart-plotting exercises in Q153.
- Chart and publication use
- Navigation aids, tides and currents, and weather considerations
- Voyage-planning concepts appropriate to near coastal operations
Domain 5: Navigation Problems: Chart Plot (Q153)
Q153 is specifically Chart Plot. It is not a generic substitute for every type of navigation problem; it is the hands-on plotting module.
- Working with a chart to solve plotting problems
- Position, course and distance work
- Accuracy and method under test conditions

Modules That Do Not Belong in Your Near Coastal Plan
Several of the most common planning mistakes come from adding modules that are not part of the route you are pursuing. Avoid the following.
- Q154 Navigation Problems: Oceans. This module belongs to the Oceans option. It must not be added to a Near Coastal scope, so do not spend study time on Oceans-specific navigation problems unless the NMC tells you otherwise.
- A "second" navigation-general module. Q152 carries a title that spans Oceans or Near Coastal, but that is one module applied to your route. Do not read the title as implying two separate navigation-general requirements.
- Alternative modules counted together. Where the published material shows alternative rules or navigation-general modules, they are alternatives. They are never simultaneous requirements to be added up.
Reduced Module Sets for Scope and Grade Increases
Not every applicant sits all five modules. The NMC also publishes reduced sets for separate increases in scope or grade. These are not extra domains attached to the full original exam; they are their own, smaller routes. The published examples relevant here include the following.
| Situation | Modules involved | Notes |
|---|---|---|
| Full original Near Coastal route | Q100, Q150, Q151, Q152, Q153 | Five modules in total |
| Increase from Great Lakes/Inland to Near Coastal | Q150 and Q152 | Q100 is added if a COLREGS limitation applies |
| Raise from Master Near Coastal under 100 to Near Coastal under 200 | Q156 | A reduced set, not the full original exam |
The lesson is that the number of modules you face depends on where you are starting from. A mariner already holding an Inland or Great Lakes credential should not plan as though they must repeat everything, and a mariner raising tonnage on an existing Near Coastal credential faces a different and smaller module set than a first-time candidate. The number of groups on this site is a preparation framework, not a universal count of examinations for every applicant.
Your Approval to Test Is the Final Word
The NMC determines the individual's assigned modules. That determination is communicated through your approval to test, and it is the only document that definitively tells you which modules you will sit. Everything on this page, and on any third-party site, is general orientation; your approval governs.
Practically, this means you should:
- Review your approval to test as soon as you receive it and list the module codes it names.
- Compare that list to the five-module route above and note any that are missing or added.
- Build your study plan around the modules you are actually assigned, not the maximum possible set.
- Contact the NMC directly if the modules listed do not match what you expected from your credential history.
Key Takeaway
Treat the five-module Near Coastal route as the reference model, then adjust to the modules named on your own approval to test. If the two differ, the approval wins.
Matching Preparation to Each Module
The five modules reward different kinds of preparation, and recognizing that early saves time. Rules of the Road (Q100) is about applying rules to situations, so scenario practice matters more than rote memorization. Deck General (Q150) and Deck Safety (Q151) draw on practical shipboard knowledge, so candidates with sea time often find them more intuitive than those studying purely from books. Navigation General (Q152) is a knowledge module, while Chart Plot (Q153) is a skill module: it is the one most improved by repeated hands-on plotting practice rather than reading.
If you want to gauge relative difficulty before committing to a schedule, How Hard Is the NM2N Exam? Complete Difficulty Guide 2026 discusses where candidates tend to feel pressure. The published matrices are the best source for exact topics; use them alongside any practice material, and remember that practice resources are independent study aids and do not imply issuer endorsement.
Sequencing Your Preparation Around the Modules
You do not need a complicated system, but ordering the modules sensibly helps. A reasonable approach is to start with the module that underpins others, build the knowledge modules next, and leave the skill-heavy plotting module for steady repetition close to test day. Adjust this to the modules you are actually assigned.
Rules of the Road (Q100)
- Work through Inland and International rules side by side
- Practice lights, shapes and signals until recall is automatic
Deck General (Q150) and Deck Safety (Q151)
- Connect each topic to shipboard practice you have seen or performed
- Review emergency and prevention procedures as scenarios
Navigation General (Q152)
- Study chart, tide, current and weather concepts for near coastal operations
- Keep the content focused on the Near Coastal route
Chart Plot (Q153) and full review
- Repeat plotting problems for speed and accuracy
- Revisit weaker modules and take timed practice sets
For a broader plan, see NM2N Study Guide 2026: How to Pass on Your First Attempt, and when you are ready to test your recall, use the practice questions on the main practice test site. A condensed refresher is available in NM2N Cheat Sheet 2026: One-Page Review of Must-Know Facts.
What Is Not Established (and How to Handle It)
It is worth being direct about what the published material does not give you, because this is where misinformation spreads. The sources reviewed for this route do not establish any of the following:
- Percentage weightings for the modules
- A single overall question count or exam duration covering the whole credential
- Current examination fees
- A population-wide pass rate
That does not mean the scope is secret. The NMC publicly publishes the modules and topic matrices, which is exactly what this article is built on. It simply means that numbers you see elsewhere should be verified against the NMC before you rely on them. If you are weighing the credential's value alongside its requirements, the analyses in Is the NM2N Certification Worth It? Complete ROI Analysis 2026 and NM2N Salary Guide 2026: Complete Earnings Analysis are useful context, while NM2N Jobs looks at where the credential is used.

Frequently Asked Questions
The full Near Coastal route has five modules: Q100 (Rules of the Road), Q150 (Deck General), Q151 (Deck Safety), Q152 (Navigation General: Oceans or Near Coastal) and Q153 (Navigation Problems: Chart Plot).
No. Q154 belongs to the Oceans option and should not be added to a Near Coastal scope. Confirm with your approval to test if you believe it was assigned.
Not necessarily. Increases in scope or grade use reduced module sets, such as Q150 and Q152 when moving from Great Lakes/Inland to Near Coastal, with Q100 added if a COLREGS limitation applies. Your NMC approval to test lists your assigned modules.
The United States Coast Guard National Maritime Center publishes the modules and topic matrices for the Oceans or Near Coastal endorsements on its examination pages, along with a deck and engineering examination guide.
The reviewed material does not establish one overall question count, duration or passing percentage for the entire credential. Check with the NMC for module-specific details, and see our guide on NM2N pass rate for what can and cannot be said about outcomes.
