What should you be looking for when inspecting the mast step and mast base, and why does this area deserve particular attention on an older boat?

A. The mast step never requires inspection since it is fully enclosed and inaccessible

B. The mast step is where the full compression load of the rig is transferred into the hull or keel — corrosion (especially where a metal mast base sits on or near standing water, or crevice corrosion where the mast meets its step) can weaken this critical load path over time, often out of sight below the cabin sole or deck

C. Mast step inspection is only relevant for masts that are deck-stepped, never for keel-stepped masts

D. The mast step carries no significant structural loading compared with the rigging itself

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
