- NM1N is the USCG National Maritime Center's Master Near Coastal less-than-100 GRT exam, built from modules Q100, Q160, Q161, Q162 and Q163.
- No single universal fee applies; your cost depends on your route, your approval to test, and current NMC fee schedules.
- Q165 is a separate raise-of-grade module for OUPV-to-Master and is not part of the original five.
- Increase-in-scope candidates may need only Q160 and Q162, plus Q100 if a COLREGS limitation applies.
What You Are Actually Paying For
When people search for the cost of the NM1N certification, they usually expect one tidy number. That expectation is the first thing to correct. National Master 100 NC (NM1N) refers to the U.S. Coast Guard National Maritime Center (NMC) examination path for Master Near Coastal on vessels of less than 100 gross register tons. It is not a private certification sold by a vendor at a flat rate. It is a regulatory credential, and the money you spend is spread across the credentialing process, your sea service documentation, your preparation, and your time away from work.
If you are still orienting yourself, start with What Is NM1N? and NM1N Requirements 2026: Eligibility, Prerequisites & How to Qualify, then come back here to plan the budget. This article focuses on how the exam structure itself shapes what you will spend, rather than quoting fee amounts that this guide cannot verify as current.
Why There Is No Single Price Tag
The NMC Examination Guide that underpins the module structure is dated to regulations effective 2014-03-24, and it is meant to be used alongside the current NMC module-topic index and your individual approval to test. It is not a fresh 2026 universal exam specification, and it does not publish one mandatory exam with one fee. Official percentage weights for the content areas are also not published here, so the five domains are best treated as unweighted preparation groups, not a single common mandatory examination.
That matters for cost because two candidates targeting the same credential can sit different combinations of modules. The candidate who needs the full five-module set carries a heavier preparation load than one whose route requires only two. The honest answer to "how much does NM1N cost?" is therefore: it depends on your route, and the first step in any budget is finding out which modules your approval actually lists.
Module Routes and What They Mean for Your Budget
The original Master Near Coastal less-than-100 GRT full examination draws on five modules: Q100, Q160, Q161, Q162 and Q163. Other pathways use different combinations, and you should not add them together. Mixing up routes is one of the easiest ways to overestimate your costs, or worse, to prepare for modules you will never be asked to sit.
| Route | Modules Involved | Budget Implication |
|---|---|---|
| Original Master Near Coastal <100 GRT (full exam) | Q100, Q160, Q161, Q162, Q163 | Largest preparation load; all five domains need study |
| Increase in scope, Great Lakes/Inland to Near Coastal | Q160 + Q162, plus Q100 where a COLREGS limitation applies | Smaller module set; skip Q161 and Q163 prep if your approval excludes them |
| OUPV to Master Near Coastal <100 raise of grade | Q165 (Navigation and Deck General/Safety) | Separate module; not part of the original five |
Key Takeaway
Read your approval to test line by line before buying any study materials. The module codes listed there, not an online summary, decide what you need to prepare for and therefore what you should spend on.
The older split headings some candidates remember, such as separate Deck General Part I and Part II or a standalone Stability Problems module, belong to a different larger-vessel module pattern. They are not the NM1N structure, and any prep product organized that way is a poor fit for this credential. The stability content that matters for NM1N lives within Q161.
The Real Cost Categories
Rather than inventing a total, it is more useful to sort your spending into categories you can verify one at a time.
1. Government and Credentialing Costs
These are the fees associated with the Coast Guard's evaluation, examination, and issuance process. They are set by the agency, vary by transaction type, and are published by the NMC. Because this guide cannot confirm current amounts, treat any figure you see on a third-party site with caution and verify it at the source: the NMC examination pages for Q100 through Q161 and Q162 through Q165.
2. Documentation and Eligibility Costs
Sea service documentation, medical and identification requirements, and any related paperwork carry their own costs, and they can be time-consuming even when they are inexpensive. The details are covered in the NM1N requirements guide. The budgeting lesson is simple: finish eligibility steps early so that exam-related spending is not stalled by missing paperwork.
3. Preparation Costs
This is the category you control most. It includes books, charts and plotting tools, practice tests, and any instructor-led course. It is also where candidates most often overspend by buying broad material that does not map to the five NM1N domains.
4. Retake and Delay Costs
Failing a module and rescheduling carries a cost in both money and momentum. Candidates who treat preparation as the cheapest insurance against retakes generally spend less overall. For a sense of how much risk to price in, read How Hard Is the NM1N Exam? and NM1N Pass Rate 2026: What the Data Shows.
Study Spending Mapped to the Five Domains
Since preparation is your most flexible expense, it helps to know what each domain actually demands, so you buy only what serves it. Below is the published topic catalog for each module, translated into spending decisions.
Domain 1: Rules of the Road, International and Inland (Q100)
Covers watchkeeping, COLREGS, and the Inland Navigational Rules. This is memorization-heavy and low-cost to prepare for: the rules text itself is the core resource.
- Know both rule sets and where they differ
- Watchkeeping principles appear here and elsewhere
- Practice questions pay off more than new textbooks
Domain 2: Deck General (Q160)
The broadest module by topic count. Seamanship, marlinspike work, purchases, blocks and tackle, temporary repairs, vessel maneuvering and handling, turn circle, pivot point, advance and transfer, wake reduction, ship's business, certificates and documents, communications, small engine operations and maintenance, and lifesaving and firefighting content.
- Firefighting content includes classes and chemistry of fire, basic firefighting and prevention, and appliances
- Signals (storm, wreck, distress, special) and survival at sea sit here
- Breadth means a good question bank beats a single textbook
Domain 3: Deck Safety (Q161)
Stability, construction, and damage control, along with emergency response. Expect trim and stability, principles of vessel construction, man overboard procedures, abandon ship procedures, emergency towing, and rescuing survivors from a ship or aircraft in distress.
- Stability topics are the conceptual hurdle; budget study time, not necessarily money
- Vessel power plants and small engine maintenance overlap with Q160
Domain 4: Navigation General, Near Coastal (Q162)
Navigation and position determination plus weather. Piloting, distance off, bearing problems, fix or running fix, dead reckoning, aids to navigation, charts and Notices to Mariners, magnetic and gyro compass, compass error and correction, meteorology, ocean currents, weather charts and reports, and tides and tidal currents.
- Compass error and tide/current calculations reward repetition
- This module appears in increase-in-scope routes, so it is a common spend
Domain 5: Navigation Problems, Chart Plot (Q163)
Hands-on plotting: piloting, distance off, bearing problems, fix or running fix, dead reckoning, electronic navigation, and instruments and accessories.
- You need real plotting tools and practice charts, which is a genuine equipment cost
- Accuracy and speed with the tools matter as much as theory
For a deeper treatment of each area, see NM1N Exam Domains 2026: Complete Guide to All 5 Content Areas.
Hidden and Indirect Costs Candidates Overlook
- Time off work. Testing and prep time can mean unpaid days, especially for working mariners and charter operators.
- Travel to a testing location. Depending on where your approval directs you to test, travel and lodging can exceed some preparation costs. Scheduling details are in NM1N Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
- Plotting equipment for Q163. Parallel rulers or a course plotter, dividers, and practice charts are small purchases that candidates sometimes forget until late.
- Approval timing. Delays in evaluation can stretch your timeline, which extends how long you pay for subscriptions or study resources.
- Lost momentum. Studying for months and then retaking a module after a long gap often means relearning material you already paid to learn.
Budget Strategy: Spend Where the Exam Hurts
One short, NM1N-specific way to sequence your preparation, and therefore your spending, is to front-load the domains that cost the most to fix late.
Q163 and Q162: Plotting and Navigation
- Buy plotting tools first and practice fixes, running fixes, and dead reckoning
- Work compass error, tides, and current problems until they are routine
Q161 and Q160: Safety and Deck General
- Cover stability and damage control first, then the wide Q160 topic list
- Use a question bank to find weak spots across seamanship, firefighting, and lifesaving
Q100: Rules of the Road
- Review COLREGS and Inland rules and drill with practice questions
- Take full-length practice tests across all modules on your route
The logic is that navigation and plotting skills take the longest to build and punish last-minute cramming, while rules memorization compresses well into the final stretch. For a fuller plan, see NM1N Study Guide 2026: How to Pass on Your First Attempt, and keep the NM1N cheat sheet handy for last-week review.
Comparing Preparation Options
| Option | Typical Cost Profile | Best For |
|---|---|---|
| Self-study with published guide and rules texts | Lowest cash outlay, highest time investment | Candidates with strong sea experience and discipline |
| Online practice tests and question banks | Low to moderate; scales with how many modules you need | Finding weak spots across Q160 and Q161 breadth; see the main practice test site |
| Instructor-led course | Highest; varies widely by provider | Candidates struggling with plotting or stability concepts |
| Hybrid approach | Moderate | Self-study for rules, targeted help for chart plot |
Many candidates find a hybrid works well: study the rules and seamanship on your own, then spend money only on the domains where practice results show weakness. You can start with a free baseline on the practice test platform to see which modules need work before you commit to anything larger.
How the Cost Connects to the Payoff
Whether the total is worthwhile depends on how you plan to use the credential. For the earnings and employment side, see NM1N Salary Guide 2026, NM1N Jobs, and Is the NM1N Certification Worth It?

Frequently Asked Questions
No. NM1N refers to a Coast Guard credential path, and fees depend on the transaction type and current NMC schedules. Your approval to test and the NMC website are the authoritative sources, so verify amounts there rather than relying on third-party figures.
For the original Master Near Coastal less-than-100 GRT full exam, the modules are Q100, Q160, Q161, Q162 and Q163. Increase-in-scope routes may use only Q160 and Q162, plus Q100 where a COLREGS limitation applies. Your approval lists exactly what you need.
No. Q165, Navigation and Deck General/Safety, is a separate raise-of-grade module for OUPV-to-Master Near Coastal under 100 GRT. It is not added to the original five, and its costs should not be stacked onto the full-exam route.
Avoid retakes. Preparing the right modules for your specific route, practicing plotting with real tools, and testing yourself before your sitting usually saves more than any discount on materials.
Official percentage weights are not published here, so treat the five domains as unweighted preparation groups. Prioritize based on your own practice results and the breadth of each module's topic list rather than assumed percentages.
