… Ah, no, those are the “100%+” lines, right? So for those we know that the ship sustained enough damage to sink it, we don’t know what amount of damage it “would” have suffered if it had been tough enough to take more than 100%, and (after looking briefly, haven’t looked more carefully yet) in all these cases we don’t know what the cause was, only that something caused the ship to sink.
Do I understand correctly that if a ship sank we simply have no record for it at all?

That’s exactly right.
