What is the difference between a hull blister caused by osmosis and simple gelcoat delamination, and why does the distinction matter?

A. There is no meaningful difference — both are always the same underlying problem

B. Osmotic blisters typically contain fluid (often with a distinctive smell) from the ongoing chemical process inside the laminate, while delamination is a separation between layers without necessarily involving that fluid or chemical process — correctly distinguishing them matters because the appropriate repair approach and urgency differ

C. Delamination only ever occurs above the waterline, so the two can never be confused

D. Osmosis and delamination are both purely cosmetic issues with no effect on hull integrity in any case

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
