- NLLL here means National Lifeboatman and Lifeboatman-Limited, administered through the U.S. Coast Guard National Maritime Center.
- Two separate options exist: Lifeboat Operator (LB01, Q445) and Lifeboat Operator Limited (LB02, Q447). You test for the one you're approved for.
- NMC lists the same 18 topic headings for both, including EPIRB, SARTs, medical care, first aid, seamanship, and compass maintenance.
- Official percentage weights aren't published, so prepare all 18 topics rather than betting on a favored few.
What This Cheat Sheet Covers (and What It Doesn't)
This page is a compressed review of the facts a National Lifeboatman and Lifeboatman-Limited (NLLL) candidate should be able to recall without hesitation. It is built around the published module-topic catalog from the United States Coast Guard National Maritime Center (NMC), which administers the deck-rating lifeboatman examinations. If you need a fuller treatment of any single area, our NLLL study guide and complete guide to both content areas go deeper.
It is equally important to say what this sheet does not claim. The NMC topic table does not establish a universal written-plus-practical duration, a total question count, or percentage weights for individual topics. The NMC Examination Guide that underpins the program refers to regulations effective 2014-03-24, so treat it as a reference point for the subject matter, not as a freshly issued 2026 exam specification. Anything involving your specific testing arrangements should be confirmed against the current NMC module-topic index and your own approval to test.
LB01 vs. LB02: The Two Endorsement Options
The most common misunderstanding about this credential is assuming it is one exam with two parts that everyone sits. It is not. NMC publishes two distinct module options, and a candidate is approved to test for the one that fits their situation.
| Item | Lifeboat Operator | Lifeboat Operator Limited |
|---|---|---|
| Module code | LB01 | LB02 |
| Exam code | Q445 | Q447 |
| Governing body | USCG National Maritime Center | USCG National Maritime Center |
| Published topic headings | 18 | 18 |
| Topic list identical to the other option? | Yes, as currently published | Yes, as currently published |
| Interchangeable endorsements? | No | No |
Notice the last row. The fact that NMC currently publishes the same topic headings under both columns does not make the endorsements interchangeable, and it does not establish that the practical assessment requirements are identical. Two endorsements can share a subject outline while differing in scope, conditions, or how skills are demonstrated. Do not assume that preparing for one automatically satisfies the other.
Key Takeaway
Before you spend a single hour studying, confirm which option (LB01/Q445 or LB02/Q447) your approval to test covers. Then use that code when you read official NMC material so you are always looking at the right row.
Eligibility, documentation, and approval steps are covered in our NLLL requirements guide, and scheduling mechanics live in the exam dates article.
The 18 Published Topics at a Glance
NMC lists the following topic headings for both LB01 and LB02. Memorize this list; it is the closest thing to an official syllabus. Spellings below follow the published catalog, including its original wording.
- Liferafts and Rescue Boat required Equipment
- Liferaft and Rescue Boat essential parts
- Operation and Function of Launching Devices
- Launching/Recovery
- Manuvering Commands and Procedures
- Personal Survival Equipment
- Distress Signals
- Signals to Attract Attention
- EPIRB
- SARTS
- Survival at Sea
- Passenger Crew Safety
- Lifesaving Appliance Regulations
- Medical Care
- First Aid
- Seamanship
- Marlinspike Seamanship
- Compass: Operation and Maintenance
Because official percentage weights are not published, no single heading can be declared "the big one." The groupings in the sections below are unweighted preparation clusters designed to make 18 headings manageable. They are a study aid, not a statement about how many questions each cluster contributes.
Equipment, Launching and Recovery Facts
Five topic headings form the equipment-and-handling cluster. Together they ask a simple question: do you know what is aboard, how it works, and how to get it into the water and back again safely?
Required Equipment and Essential Parts
Two headings address what liferafts and rescue boats must carry and what their principal components are.
- Be able to name the required equipment for both liferafts and rescue boats, not just lifeboats.
- Distinguish between equipment that is required and parts that are essential to the craft's function; the catalog treats these as separate headings.
- Know the purpose of each item, not merely its name. Recall questions often turn on function.
Launching Devices, Launching and Recovery
Two headings cover the operation and function of launching devices and the launching/recovery process itself.
- Understand how launching devices operate and what each major component does.
- Be ready to sequence the launch and recovery steps in order and explain why order matters.
- Link launching knowledge to the maneuvering heading: moving the boat well after it is waterborne is part of the same competence.
Maneuvering Commands and Procedures
This heading rewards clarity. Expect to recognize standard commands and the procedures they trigger.
- Learn the commands as a working vocabulary, tied to the action each one produces.
- Practice thinking through a scenario from the coxswain's seat: what is said, what happens next.
If you are weighing how demanding these areas are relative to the rest, see our candid breakdown in how hard the NLLL exam is.
Distress Signals, EPIRB and SARTs
Four headings in the catalog deal with getting help and being found: Distress Signals, Signals to Attract Attention, EPIRB, and SARTS. They are small in word count but easy to confuse with each other, which is exactly why they deserve a dedicated cheat-sheet block.
| Topic | What to Be Able to Explain |
|---|---|
| Distress Signals | Which signals indicate a vessel or person is in grave danger and requires assistance. |
| Signals to Attract Attention | Which signals draw notice without necessarily declaring distress; know how this differs from the distress heading. |
| EPIRB | The purpose of an emergency position-indicating radio beacon and what it does to help rescuers locate a vessel. |
| SARTS | The purpose of search and rescue transponders and how they assist searchers in locating a craft or survivors. |
A reliable memory technique is to write one sentence per device beginning with "I would use this when..." That forces you to attach each item to a situation rather than a definition alone.
Survival at Sea, Medical Care and First Aid
This cluster covers the human side of the job: keeping people alive and as well as possible until rescue arrives. It spans four headings: Personal Survival Equipment, Survival at Sea, Medical Care, and First Aid.
Personal Survival Equipment and Survival at Sea
Know what individuals wear or carry and how to manage a survival situation once the vessel is abandoned.
- Be able to describe personal survival equipment and its proper use.
- Understand the priorities of survival at sea as a connected set of decisions, not isolated tips.
- Tie this cluster back to the equipment cluster: what is in the boat supports what you do in the water.
Medical Care and First Aid
NMC lists these as two headings, so expect them to be treated as related but distinct bodies of knowledge.
- Review basic first aid responses and the logic of what to do first.
- Review medical care as it applies to survivors over a longer period, not only the immediate response.
- Practice explaining your reasoning aloud; sequencing errors are a common way to lose points on scenario-style questions.
These headings are also the ones most likely to benefit from hands-on familiarity if you have any shipboard training behind you. Our NLLL training overview discusses how coursework and practical exposure fit alongside written preparation.
Seamanship, Marlinspike and the Compass
Three headings round out the practical-skills cluster: Seamanship, Marlinspike Seamanship, and Compass: Operation and Maintenance.
- Seamanship: General good practice in operating and handling a small craft at sea.
- Marlinspike Seamanship: The rope-and-line side of the trade: knots, bends, hitches, and care of cordage. Be ready to identify a knot by its purpose and explain when you would choose it.
- Compass: Operation and Maintenance: How to use a compass for steering and how to look after it so it stays reliable. Notice that "maintenance" is part of the heading, so do not stop at reading a bearing.
Key Takeaway
For marlinspike and compass material, pair every term with a use case. "What is it?" is rarely the hardest version of the question; "which would you use here, and why?" is.
Lifesaving Appliance Regulations and Passenger/Crew Safety
The final two headings, Lifesaving Appliance Regulations and Passenger Crew Safety, tie the technical content to rules and responsibilities.
- Lifesaving Appliance Regulations: Know that the equipment and handling topics above are governed by regulatory requirements. Study the regulations alongside the equipment so the rules feel like the reason behind the hardware, not a separate memorization project.
- Passenger Crew Safety: Understand the lifeboatman's responsibility for the people in their charge, including how safety considerations shape the way a launch or evacuation is carried out.
Because regulations can change, rely on current official NMC sources for rule-specific details rather than on any dated summary, including this one.
Sequencing Your Review by Topic Group
Since no official weights exist, a sensible plan gives every cluster at least one dedicated pass and then loops back to your weakest areas. The timeline below is one way to order the clusters; adjust it to your own testing date.
Equipment and Handling
- Required equipment and essential parts for liferafts and rescue boats
- Launching devices, launching/recovery, maneuvering commands
Signals and Survival
- Distress signals vs. signals to attract attention; EPIRB and SARTS
- Personal survival equipment, survival at sea, medical care, first aid
Skills, Rules, and Review
- Seamanship, marlinspike seamanship, compass operation and maintenance
- Lifesaving appliance regulations and passenger/crew safety; full-list recall of all 18 headings
Why this order? Equipment knowledge is the foundation the other clusters lean on, signals and survival build on it, and regulations make the most sense once you already know what they regulate. For a broader plan, return to the NLLL study guide.
Pre-Exam Reminders and Verification Checklist
Use this short list in the days before you test. Several items are verification tasks, because the facts that matter most for your own exam are the ones specific to your approval.
- Confirm whether you are approved for LB01 (Q445) or LB02 (Q447).
- Check the current NMC module-topic index for any changes to the published headings.
- Confirm the format, duration, and practical components that apply to your approval, since the topic table alone does not set these.
- Verify fee and scheduling details through official channels; see NLLL certification cost and exam dates for what to look for.
- Review the passing standard that applies to you; our passing score article explains how to find it.
- Run a final recall drill of all 18 headings from memory, then take a timed practice session on the NLLL practice test to expose gaps.
If you are still deciding whether the credential suits your goals, see whether it is worth it, the earnings analysis, and the NLLL jobs overview. When you are ready to drill, the practice exam site is the place to start.
Frequently Asked Questions
No. They are two distinct endorsement options, not two modules everyone must sit. You test for the one your approval covers, whether Lifeboat Operator (LB01, Q445) or Lifeboat Operator Limited (LB02, Q447).
No. NMC currently publishes the same 18 topic headings for each, but that shared list does not make the endorsements interchangeable or prove their practical assessment requirements are identical.
Official percentage weights are not published, so no topic can be ranked as heaviest. Prepare all 18 headings, and use practice results to decide where to spend extra time.
The NMC Examination Guide referenced here relates to regulations effective 2014-03-24. Use it for subject matter alongside the current NMC module-topic index and your individual approval to test, not as a new 2026 universal specification.
