Why are battery terminals and the battery master switch particularly prone to problems in a marine environment, compared to the same components on a road vehicle?

A. Marine electrical components are actually more resistant to corrosion than automotive ones

B. The combination of salt air, humidity, and vibration accelerates corrosion at electrical connections far faster than in a typical land environment — a loose or corroded connection can cause intermittent faults, voltage drop, or complete failure right when equipment is needed most

C. Corrosion only affects the battery casing itself, never the terminals or connections

D. This is only a concern for boats kept permanently in salt water, never for boats on a mooring or in a marina

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
