What is the general purpose of a "watch system" on a passage of more than a few hours, even with a small crew?

A. Watch systems are only relevant on ocean crossings, never on coastal passages

B. A watch system exists purely to assign blame if something goes wrong during a particular period

C. A watch system shares the workload of keeping a proper lookout and managing the boat across the crew, so no one person is left exhausted from staying alert continuously — genuine rest between watches matters for everyone's safety and judgement, not just comfort

D. With a crew of two or fewer, watch systems serve no useful purpose

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

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

C. Testing should wait until cargo operations begin

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

A. Only the weather forecast for the next watch

B. The lunch schedule for the deck team

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

D. The cargo manifest for the next port
