What record-keeping obligation applies to passenger safety briefings and musters under good yacht management practice, even where not always a strict line-by-line Code requirement?

A. Records are only relevant if a passenger explicitly requests written confirmation of having received a briefing

B. No record of any kind is useful or expected for passenger safety briefings

C. Record-keeping for safety briefings is solely the responsibility of the charter management company, with no onboard documentation expected

D. Maintaining a record of when briefings/musters were conducted, who attended, and what was covered — providing an auditable trail and a prompt to ensure the briefing is not skipped or rushed under guest social pressure ("we don't need that, let's just go")

A. A safety briefing is only required if a passenger specifically requests one

B. No safety briefing is required if the charter is less than 24 hours in duration

C. A muster/safety briefing covering emergency signals, muster stations, life jacket location and use, and basic emergency procedures, given before or shortly after departure — not assumed to be unnecessary because guests are "experienced" or have sailed before

D. Safety briefings are only mandatory for first-time charter guests, not repeat clients

A. Passengers are excluded entirely from any emergency procedure and are expected to remain in their cabins regardless of the emergency type

B. Passengers are not trained crew and cannot be relied upon to perform emergency duties — the Code's provisions (briefing content, muster procedures, crew-to-passenger ratios for assistance) are built around crew actively managing and guiding passengers through an emergency, not passengers being expected to self-manage

C. Passengers are expected to perform identical emergency duties to trained crew once briefed

D. There is no meaningful distinction between passenger and crew responsibilities under the Code
