- Q154 Navigation Problems: Oceans belongs to the Oceans option and is not part of Near Coastal training.
- Your assigned modules come from your NMC approval, so train to that approval, not to a generic list.
- Q153 is Chart Plot specifically; Q152 covers navigation general topics and should not be mistaken for a second chart-plot module.
What "Training" Means for NM2N
When mariners search for NM2N training, they are usually asking one practical question: what do I actually need to learn, and in what order? For National Master 200 NC (NM2N), the answer is anchored in a published structure. The United States Coast Guard National Maritime Center (NMC) publishes the examination modules and topic matrices for the Oceans or Near Coastal endorsement family, and the Near Coastal route within ONC05 is built from five named modules.
That makes training for this credential different from preparing for an exam with a single blended question pool. You are not studying one giant body of knowledge. You are preparing for a defined set of modules, each with its own subject boundaries. If you want the big-picture definition before going deeper, see What Is NM2N? and NM2N Certification.
Start With Your Route: Which Modules Are Yours
Before you open a single study resource, work out which modules you will actually sit. This is the single most valuable training decision you can make, because the published material covers several routes and scopes, and not every applicant takes every module.
The full Near Coastal route
For the full original route, the exact module set is Q100, Q150, Q151, Q152 and Q153. That is five modules, and it is the scope this article treats as the baseline. The published guide reference for this grouping is section 2.1.1.3, printed page 17 of the NMC deck and engineering examination guide.
Reduced module sets for upgrades and raises
Some candidates are not taking the full original examination. Separate increases in scope or grade have reduced module sets. Two examples illustrate the pattern:
- A candidate moving from Great Lakes/Inland to Near Coastal may be looking at Q150 plus Q152, with Q100 added if a COLREGS limitation applies.
- A candidate raising grade from Master Near Coastal under 100 GRT to Near Coastal under 200 GRT may be looking at Q156 rather than the full five-module route.
These are not extra domains layered on top of the full exam. They are alternative, smaller paths. Do not combine them with the five-module route in your head, and do not count alternative or navigation-general modules together as simultaneous requirements.
Key Takeaway
Check your NMC approval to test first, then match each listed module to the training blocks below. If a module is not on your approval, do not spend weeks preparing for it. Eligibility questions are covered in NM2N Requirements 2026.
Module-by-Module Training Map
The table below organizes the five full-route modules into preparation groups. These groups are unweighted: the published materials establish the modules and topic matrices, not percentage weights or a single overall question count, so treat each module as its own study target rather than a slice of a pie chart.
| Module | Title | Training Emphasis | Nature of Work |
|---|---|---|---|
| Q100 | Rules of the Road: Inland and International | Applying navigation rules to situations | Rule recall plus scenario judgment |
| Q150 | Deck General | Broad deck-department knowledge | Wide-ranging reference recall |
| Q151 | Deck Safety | Safety, emergency and protective practices | Procedure and regulation recall |
| Q152 | Navigation General: Oceans or Near Coastal | Navigation concepts for the Near Coastal route | Concept-based, applied to Near Coastal |
| Q153 | Navigation Problems: Chart Plot | Working problems on the chart | Hands-on plotting and calculation |
For a deeper breakdown of how these areas fit together, read NM2N Exam Domains 2026: Complete Guide to All 5 Content Areas.
Training for Rules of the Road (Q100)
Domain 1: Rules of the Road: Inland and International (Q100)
This module tests the navigation rules under both the Inland and International frameworks. The training challenge is not memorizing a single rule set but keeping two related sets distinct.
- Learn the situations where Inland and International rules differ, rather than treating them as interchangeable.
- Practice classifying vessels, lights and shapes quickly, since those recognition tasks reward repetition.
- Work through right-of-way and conduct-of-vessels scenarios until you can state the governing rule and the reason for it.
- Pay attention to sound signals and their meanings in each rule set.
Q100 is also the module most likely to appear as an add-on. As noted above, a candidate stepping up from Great Lakes/Inland to Near Coastal may need Q100 only if a COLREGS limitation applies. If that is you, this single module could be your most important training block.
A practical technique here: build two columns for every rule topic, one for Inland and one for International, and fill in only the differences. Studying the differences is far more efficient than rereading what the two sets share.
Training for Deck General and Deck Safety (Q150, Q151)
Q150: Deck General
Domain 2: Deck General (Q150)
Deck General is the broadest module in the set. It draws on the wide body of practical and regulatory knowledge expected of a deck officer.
- Expect breadth over depth: many topics, each tested at a working-knowledge level.
- Organize your notes by topic cluster so you can review whole areas in one sitting.
- Use the NMC topic matrices as your checklist, ticking off each heading as you cover it.
Q151: Deck Safety
Domain 3: Deck Safety (Q151)
Deck Safety focuses on the protective and emergency side of vessel operation.
- Prioritize procedures and regulatory requirements that govern safe operation and emergency response.
- Tie each safety topic to a real shipboard scenario so the procedure sticks.
- Review these topics repeatedly; safety content rewards familiarity with exact requirements.
These two modules share a character: both are largely recall-and-application subjects, so they pair well in the same study block. Candidates who find the volume of reference material daunting should read How Hard Is the NM2N Exam? for a realistic view of where the difficulty tends to sit.
Training for Navigation (Q152, Q153)
Navigation is where candidates most often confuse scope, so precision matters. There are two navigation modules on the Near Coastal route, and they are not interchangeable.
Domain 4: Navigation General: Oceans or Near Coastal (Q152)
Study the navigation concepts as they apply to Near Coastal operation. Because the module title is shared across routes, rely on the topic matrix to confirm which subjects are in scope for your assignment.
- Concentrate on coastal navigation concepts relevant to the Near Coastal route.
- Treat this as a concepts module that supports the plotting work in Q153.
Domain 5: Navigation Problems: Chart Plot (Q153)
This is the hands-on module. You solve problems by plotting and calculating on a chart, so reading about it is not enough.
- Practice plotting positions, courses and bearings repeatedly until the mechanics are automatic.
- Work problems end to end, from the given information to the final answer.
- Check each result for reasonableness, since small plotting errors compound quickly.
- Build speed only after accuracy is reliable.
Q153 is the module where practice volume matters most. Unlike recall modules, you cannot read your way to competence. Set aside dedicated time for worked problems, and consider using the NM2N practice test site to reinforce the concept side of navigation between plotting sessions.
Sequencing the Modules in a Realistic Plan
This is the one place where scheduling comes in, and it is tied directly to the module structure. The logic: start with the module that underpins the others, interleave the heavy-recall subjects, and give Chart Plot the longest runway because it depends on hands-on repetition.
Rules of the Road (Q100) and navigation concepts (Q152)
- Build the Inland versus International difference table.
- Begin Q152 concepts, since they feed directly into plotting later.
Deck General (Q150) and Deck Safety (Q151)
- Work through the topic matrix heading by heading.
- Pair safety procedures with shipboard scenarios.
Chart Plot (Q153) as the focus
- Daily worked plotting problems.
- Light review of Q100, Q150 and Q151 to prevent decay.
If you hold a reduced module set, compress this plan accordingly. A candidate with only Q150 and Q152, for example, can fold the schedule into a much shorter window. For a fuller strategy, see the NM2N Study Guide 2026 and, for a quick last-pass reference, the NM2N Cheat Sheet.
Approved Courses vs. Self-Directed Preparation
Candidates generally choose between structured instruction and independent preparation, and many blend the two. The right mix depends on your sea-service background, your comfort with chart work, and how much of the material is new to you.
| Approach | Best Suited For | Watch Out For |
|---|---|---|
| Structured course | Candidates new to chart plotting or returning after a long gap | Course scope may be broader than your assigned modules |
| Self-directed study | Experienced mariners refreshing known material | Drifting into out-of-scope topics without the matrix as a guide |
| Blended | Most candidates, especially for Q153 | Paying for instruction in modules you do not need |
Whichever route you take, keep the NMC topic matrices at the center of your preparation. They define what is in scope. Cost questions around courses and testing are addressed in NM2N Certification Cost 2026, though note that this article does not state current fee figures, since the sources reviewed do not establish them. Scheduling and timing details are covered in NM2N Exam Dates 2026.
Training Mistakes Specific to This Credential
- Studying Q154 content. Oceans navigation problems belong to a different option. Including them in Near Coastal training wastes effort.
- Counting modules together that are alternatives. Alternative Rules or Navigation General modules are never simultaneous requirements.
- Treating Q153 as all of navigation. Chart Plot is one module; Q152 carries the general navigation concepts.
- Assuming everyone takes five modules. Upgrades and raises use reduced sets. Your approval to test is the authority.
- Relying on a single guide's date. The published guide reflects regulations effective March 24, 2014, and current indexed NMC matrices corroborate the module headings. Cross-check against the current matrices before finalizing your plan.
- Skipping plotting repetition. Recall modules tolerate cramming; Chart Plot does not.
Key Takeaway
Effective NM2N training is mostly a scoping exercise followed by targeted practice. Confirm your modules, study the differences in Q100, work the matrices for Q150 and Q151, and give Q153 the most hands-on time. For career context once you are through, see NM2N Jobs and Is the NM2N Certification Worth It?
No overall pass rate, passing percentage or total question count is established for this credential in the sources reviewed, so be wary of any training provider that quotes precise figures without citing NMC. Questions on scoring are explored in NM2N Passing Score 2026 and NM2N Pass Rate 2026, which treat the available data with appropriate caution.
Frequently Asked Questions
The full original Near Coastal route under ONC05 has five modules: Q100, Q150, Q151, Q152 and Q153. Applicants taking upgrades or raises of grade may have a reduced set, so training should follow the modules on your NMC approval to test.
No, not for a Near Coastal route. Q154 belongs to the Oceans option and is not part of the Near Coastal scope. Focus your navigation training on Q152 and Q153.
Q152 is Navigation General: Oceans or Near Coastal, applied here to Near Coastal. Q153 is Navigation Problems: Chart Plot, which is specifically about working plotting problems on a chart. They are separate modules with different training needs.
The NMC publicly publishes the examination modules and topic matrices for the Oceans or Near Coastal endorsements. Use those matrices as your checklist, and confirm your assigned modules through your approval to test rather than assuming a generic list.
No. The published guide reflects regulations effective March 24, 2014, and current indexed NMC matrices corroborate the same module headings. It is not a newly issued 2026 blueprint, so verify against current NMC postings and use NM2N Exam Prep practice material to reinforce your preparation.
