What is a boat's bonding system, and what is it intended to do?

A. A bonding system is purely cosmetic trim connecting different metal fittings

B. A bonding system electrically connects underwater metal fittings (skin fittings, prop shaft, rudder stock etc.) together and typically to the sacrificial anode, so galvanic and stray-current corrosion is directed toward the anode rather than eating away at whichever fitting happens to be the most reactive metal on board

C. Bonding refers only to how the hull and deck mouldings are joined during construction

D. Bonding systems are only fitted to steel-hulled vessels

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
