NM2N Cheat Sheet 2026: One-Page Review of Must-Know Facts

TL;DR
  • The full Near Coastal route is five modules: Q100, Q150, Q151, Q152 and Q153.
  • Q154 Navigation Problems: Oceans belongs to the Oceans option and does not apply to Near Coastal.
  • Q153 is specifically Chart Plot, not a catch-all for every navigation problem.
  • Your NMC approval to test, not a general list, determines which modules you actually sit.

What This Cheat Sheet Covers (and What It Doesn't)

This page is a compact reference for the National Master 200 NC (NM2N) route: the United States Coast Guard National Maritime Center (NMC) examination modules under the ONC05 scope for the Near Coastal credential. It condenses the module structure, the topic areas behind each module, and the common scoping mistakes that cause candidates to study the wrong material.

It is not a substitute for working through the published topic matrices or practicing with realistic questions. If you want the deeper walk-through of each content area, the NM2N Exam Domains 2026: Complete Guide to All 5 Content Areas goes module by module. If you want a full preparation plan, start with the NM2N Study Guide 2026: How to Pass on Your First Attempt.

Source note: The module headings here were checked against NMC pages and the published Deck and Engineering examination guide. That guide is the regulations-effective-March-24-2014 document, not a newly issued 2026 blueprint, though current indexed NMC matrices corroborate the module headings. This packet does not establish percentages, an overall question count or duration, current fees, or a population pass rate, so none are given here.

The Five-Module Map at a Glance

The full exam route for Near Coastal consists of five issuer-published modules. Think of them as five preparation groups rather than five equally weighted domains; the NMC publishes the modules and topic matrices, but this guide does not assign weights or percentages to them.

ModuleTitleCore Focus
Q100Rules of the Road: Inland and InternationalNavigation rules, lights, signals, right-of-way
Q150Deck GeneralGeneral deck knowledge and vessel operations
Q151Deck SafetySafety, emergency and preventive practices on deck
Q152Navigation General: Oceans or Near CoastalNavigation theory applied to the Near Coastal route
Q153Navigation Problems: Chart PlotWorking chart-plotting problems

The published guide reference for this scope is section 2.1.1.3 (printed page 17). When you review the official matrices, use that reference point to confirm you are reading the Near Coastal route and not an adjacent endorsement.

Q100: Rules of the Road, Inland and International

Q100 is the module most candidates describe as the one that rewards precision. It covers both the Inland and International rule sets, so you need to know not just each rule but where the two regimes diverge.

Q100 Must-Know Areas

Be able to apply rules to a situation, not merely recite them.

  • Which rule set applies in a given body of water, and where each takes effect
  • Vessel lights and shapes for different vessel types and operating conditions
  • Sound and light signals, including maneuvering and warning signals
  • Steering and sailing rules: overtaking, head-on and crossing situations
  • Stand-on and give-way responsibilities and the actions each vessel must take
  • Conduct in restricted visibility

A useful drill is to take a single scenario, such as two power-driven vessels meeting in a channel, and answer it under both rule sets. The differences you uncover are exactly the details that tend to show up in question stems.

Q150: Deck General

Q150 is the broad deck-knowledge module. It rewards candidates who have genuinely worked on deck, because the content is practical and operational rather than purely theoretical.

Q150 Must-Know Areas

Expect practical seamanship and vessel-handling knowledge.

  • Vessel construction, terminology and basic stability concepts
  • Mooring, anchoring and line handling
  • Cargo and general operational considerations
  • Equipment and routine shipboard procedures
  • Responsibilities of the licensed officer in routine operations

Because Q150 is a general module, the best way to study it is to read the official topic matrix first and mark every heading you could not explain aloud to a junior deckhand. Those gaps are your study list.

Q151: Deck Safety

Q151 centers on safety on deck and the procedures that protect crew and vessel. It pairs naturally with Q150, and many candidates find the two modules overlap in vocabulary even though they are scoped separately.

Q151 Must-Know Areas

Safety content is about procedure, readiness and judgment.

  • Emergency response and drills
  • Lifesaving and firefighting equipment and its proper use
  • Hazard recognition and preventive safety practices
  • Pollution prevention and response responsibilities
  • Safe work practices and the officer's duty to the crew
Practical angle: Safety questions often reward the answer a prudent, safety-first officer would choose. When two options look plausible, the one that prioritizes life safety and following established procedure is usually the stronger choice.

Q152: Navigation General for the Near Coastal Route

Q152's official title spans both Oceans and Near Coastal: Navigation General: Oceans or Near Coastal. For this credential you apply it to the Near Coastal route. Do not treat it as a second, separate navigation-general module; it is one module, and it is the theory counterpart to the plotting work in Q153.

Q152 Must-Know Areas

Study the concepts that support safe passage planning and position-keeping.

  • Chart reading, symbols and publications used in navigation
  • Aids to navigation and their characteristics
  • Piloting methods and position fixing
  • Compasses and heading corrections
  • Tides, currents and their effect on a vessel's track
  • Weather awareness as it relates to passage planning

Q152 and Q153 work as a pair. Q152 gives you the reasoning; Q153 tests whether you can carry that reasoning through to a worked plot. Candidates who study them together tend to find both easier.

Q153: Navigation Problems, Chart Plot

Q153 is specifically Chart Plot. It is not a generic placeholder for every kind of navigation problem, so keep your preparation focused on plotting skills.

Q153 Must-Know Skills

This module is a skills test. Reading about plotting is not enough.

  • Laying off courses and determining positions on the chart
  • Applying variation and deviation correctly in both directions
  • Working set, drift, speed and time relationships
  • Using the chart tools and scales accurately
  • Checking your work for reasonableness before committing to an answer

Plotting accuracy comes from repetition. Work problems until the sequence of steps is automatic, then deliberately slow down on the correction steps, where sign errors are easiest to make.

Scope Traps: Modules You Should Not Add to Your List

Much of the confusion around this credential comes from adjacent modules that look related. Use this table to keep your scope clean.

ItemWhere It BelongsAdd to Near Coastal Full Route?
Q154 Navigation Problems: OceansOceans optionNo
Q152 (Oceans or Near Coastal)One module, applied to Near Coastal hereYes, once, as the navigation-general module
Q153 Chart PlotChart plotting specificallyYes, but not as a stand-in for all navigation problems
Alternative Rules or Navigation General modulesAlternative pathsNever count together as simultaneous requirements
Raise-of-grade and route-extension modules (such as Q156)Separate upgrades or extensionsNo, they are not extra domains of the full original exam
Reduced module sets: Some increases in scope or grade use shortened module sets. Examples include Q150 plus Q152 for a move from Great Lakes and Inland to Near Coastal (with Q100 added if a COLREGS limitation applies), and Q156 for an increase from Master Near Coastal under 100 tons to Near Coastal under 200 tons. These are separate pathways, not additional domains on the full original exam.

The number of groups on this page is not a universal count of examinations for every applicant. Your NMC approval to test determines the modules assigned to you, so always rely on that document over any summary, including this one.

Sequencing the Modules in Your Review Calendar

This is the only study-planning section in this article, and it is tied to how the five modules relate to one another rather than to a generic schedule.

Week 1

Q100 Rules of the Road

  • Learn both rule sets side by side and note the differences
  • Start early because rule recall benefits from repeated exposure
Week 2

Q150 and Q151 Deck Modules

  • Work the general and safety topic matrices together, since vocabulary overlaps
  • Flag any topic you cannot explain aloud
Week 3

Q152 then Q153

  • Cover Q152 theory first, then immediately practice Q153 plots that use it
  • Finish with timed mixed practice across all five modules

Keep Rules of the Road in light rotation through the final weeks so it does not fade while you focus on plotting. For a realistic sense of how demanding the route is, see How Hard Is the NM2N Exam? Complete Difficulty Guide 2026.

Final-Week Checklist

  1. Confirm in your NMC approval to test exactly which modules you are assigned.
  2. Re-read the official topic matrix for each assigned module and check off every heading.
  3. Redo any Q153 plot where you made a correction-step error.
  4. Rehearse Q100 lights, signals and steering rules under both Inland and International rules.
  5. Take a full mixed practice set on the NM2N Exam Prep practice test site to confirm timing and recall.
  6. Review the logistics: NM2N Exam Dates 2026: Testing Windows, Deadlines & Scheduling and NM2N Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Frequently Asked Questions

How many modules are on the full Near Coastal route?

The full ONC05 Near Coastal route lists five modules: Q100, Q150, Q151, Q152 and Q153. Your individual NMC approval to test determines which modules you are actually assigned, since upgrades and extensions use reduced sets.

Do I need Q154 Navigation Problems: Oceans for Near Coastal?

No. Q154 belongs to the Oceans option and should not be added to the Near Coastal scope. For Near Coastal, the plotting module is Q153 Chart Plot.

Is Q152 a separate module from the Near Coastal navigation general content?

No. Q152's official title spans Oceans or Near Coastal, but it is a single module. For this credential you apply it to the Near Coastal route rather than counting a second navigation-general module.

Does this cheat sheet include question counts, time limits or percentages?

No. The sources reviewed do not establish a single overall question count, duration, domain percentages, current fees or a population pass rate, so this article does not state any. Check the NMC directly for current details, and see NM2N Pass Rate 2026: What the Data Shows for what can and cannot be said about results.
