What is the purpose of the "Mayday" call format, and roughly what information should it include?

A. Mayday is only used for reporting minor equipment faults, not genuine emergencies

B. "Mayday" (repeated three times) signals a genuine life-threatening emergency and should be followed by the vessel's identity, position, the nature of the emergency, and the number of people on board — a clear, standard format that lets anyone hearing it, including other crew, pass it on correctly if needed

C. Mayday calls should never include the vessel's position, to avoid revealing the vessel's location

D. Only the skipper is ever permitted to know the Mayday call format

A. Nothing — a test lift can proceed immediately after repairs

B. Testing should wait until cargo operations begin

C. The area within the grab's swing radius should be cleared of personnel before the lift

D. Only the crane operator needs to be aware the lift is happening

A. Who must remain clear of the exclusion zone while the lift takes place

B. The lunch schedule for the deck team

C. Only the weather forecast for the next watch

D. The cargo manifest for the next port
