As crew, what is a simple, useful thing to understand about "tacking" versus "gybing", even before you're steering through either yourself?

A. Tacking and gybing are two names for exactly the same manoeuvre

B. Both change the boat's course through the wind to the opposite tack, but tacking turns the bow through the wind (generally the calmer, more controlled way) while gybing turns the stern through the wind, which can bring the boom across quickly and with more force — knowing which is happening helps crew understand why the skipper calls a warning and to keep clear of the boom during a gybe especially

C. Only the skipper needs to understand the difference; crew positioning is unaffected either way

D. Gybing is always the safer of the two manoeuvres in any wind strength

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
