What is the role of a rescue boat, as distinct from a lifeboat, and what training does its operation specifically require?

A. Rescue boat operation requires no training beyond basic PST, since it is considered simpler than lifeboat operation

B. Rescue boats are only used for routine crew transport between vessels, never for actual rescue operations

C. A rescue boat is designed primarily to recover persons from the water and to marshal/assist liferafts, typically faster and more manoeuvrable than a lifeboat — operating it requires specific small-boat handling skills, person-in-water recovery technique, and launching/recovery procedure under way, distinct from a lifeboat's primary role of carrying a full survival complement

D. A rescue boat and a lifeboat serve identical functions and require identical operator skills with no distinction

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
