About the USCG Lifeboatman Limited Exam
The USCG Lifeboatman Limited / Lifeboat Operator Limited exam (NMC LB02, Q447) is the written test path for mariners who take charge of liferafts, rescue boats, and other survival equipment on vessels where lifeboats are not installed. Under 46 CFR 12.409, it is distinct from full Lifeboatman / Lifeboat Operator (LB01 Q445). It validates launching and handling of inflatable liferafts and rescue craft, equipment knowledge, distress signaling, and post-abandonment survival actions — and always includes a mandatory practical demonstration.
Assessment
LB02 path: Q447 Lifeboatman Limited / Lifeboat Operator Limited (50 MCQ, 70% pass) covering liferafts, rescue boats, survival craft other than lifeboats, launching devices, equipment, distress signals, and survival knowledge — plus a mandatory practical demonstration (take charge of rescue boat/liferaft during and after launch, operate rescue boat engine, manage survivors, recover rescue boats, use locating/communication devices). Q448 is the renewal open-book exercise (50 questions, 90%). A USCG-approved PSC-Limited course is a common substitute for written and practical requirements when completed within the allowed application window.

Frequently Asked Questions
How many questions are on the USCG Lifeboatman Limited written exam?
The Coast Guard's Q447 Lifeboatman Limited / Lifeboat Operator Limited sample-exam path is a 50-question multiple-choice written test. In addition to the written exam, candidates must pass a practical demonstration under 46 CFR 12.409. The Q448 renewal open-book exercise is a separate 50-question module at 90% for eligible renewals.
What passing score do I need?
Q447 requires 70% to pass. Q448 Lifeboatman Limited Renewal Open Book Exercise requires 90%.
How is Lifeboatman Limited different from full Lifeboatman?
Lifeboatman Limited / Lifeboat Operator Limited (LB02 Q447) applies to vessels fitted with liferafts and rescue boats but not lifeboats. Full Lifeboatman / Lifeboat Operator (LB01 Q445) covers survival craft including lifeboats. Limited examination content focuses on liferafts, rescue boats, and launching devices other than open lifeboats.
Can I skip the Q447 written exam by taking a course?
Yes. A USCG-approved Proficiency in Survival Craft — Limited course commonly satisfies the training, practical demonstration, and written examination requirements of 46 CFR 12.409(b)(3) when completed within the allowed application window. You still must apply through NMC for the endorsement.
What is included in the practical demonstration?
Under 46 CFR 12.409, the practical must show ability to take charge of a rescue boat, liferaft, or other lifesaving apparatus (other than lifeboats) during and after launch; operate a rescue boat engine; manage a survival craft and survivors after abandoning ship; safely recover rescue boats; and use locating and communication devices.
How much does the Q447 exam cost?
Table 1 to 46 CFR 10.219(a) charges an original MMC rating endorsement other than a qualified rating $95 for evaluation and $45 for issuance, with no separate examination fee — about $140 in total. A renewal is $50 plus $45. Lifeboat Operator-Limited is not a qualified rating under 46 CFR 10.107, which reserves that term for Able Seafarer, QMED, and tank vessel endorsements. If you apply for an officer endorsement at the same time, only the officer fees are charged. PSC-Limited course tuition, if used as the alternative path, is set by each training provider. Pay through Pay.gov.
Is this free practice bank an official Coast Guard exam or practical simulation?
No. This is a free English-language multiple-choice study aid for Q447 knowledge areas. Official modules are administered by the Coast Guard at RECs. The mandatory practical demonstration is a hands-on assessment that this MCQ bank does not and cannot replace.
What sea service is required?
Under 46 CFR 12.409, at least 12 months of sea service in any department on ocean, coastwise, inland, or Great Lakes routes — or at least 6 months of sea service plus successful completion of an approved course. Applicants must also be at least 18, meet medical and drug-testing rules, and speak/understand English for the rating.
