Who, specifically, is required to hold a PSCRB certificate aboard a vessel, and how does this connect to the muster list?

A. PSCRB certification has no specific connection to the muster list and is assigned independently of emergency roles

B. Every single person aboard the vessel, regardless of their assigned muster list role, must hold a PSCRB certificate

C. Any crew member designated on the muster list with responsibility for launching, taking charge of, or operating survival craft and rescue boats — typically including the officer assigned as coxswain of each lifeboat and rescue boat, plus sufficient additional certified crew to ensure these roles can be filled even if some designated individuals are unavailable or injured

D. Only the master is required to hold PSCRB, with no requirement for any other officer or rating

A. PSCRB is required for every seafarer regardless of muster list role, with no distinction from PST

B. PSCRB only covers liferafts, while PST covers lifeboats — the two trainings simply split equipment types

C. PST gives every seafarer the basic personal survival skills needed to use equipment and survive once in a liferaft, while PSCRB is a separate, more advanced certificate required for crew specifically designated on the muster list to launch, command, or operate lifeboats and rescue boats — including davit operation, engine handling, and craft manoeuvring

D. PSCRB and PST cover identical content and are simply two names for the same training

A. Occupants should stand and hold the gunwale for stability during the lowering process

B. The area below and around the lifeboat is clear of obstructions and personnel not involved in launching; the falls (wires) are correctly led and free to run; the brake mechanism is functioning; occupants are seated and braced correctly; and there is clear communication established between the person controlling the davit and anyone in the boat

C. No pre-launch checks are necessary as long as the davit mechanism appears undamaged on visual inspection

D. Only the lifeboat's engine needs checking before launch; the davit and fall mechanisms are assumed reliable without inspection
