A certificated lifeboatman assigned to command the lifeboat must __________.

Correct Answer: Option B — have a list of the persons assigned to the lifeboat

46 CFR 109.301 requires the person in charge of a lifeboat to maintain an accurate list of all persons assigned to that craft. This is essential for accountability during musters and abandon-ship procedures, ensuring that every individual is accounted for and safely evacuated during a critical situation.
