This is kind of an unusual question because of the word "normally." I have seen people incorporate this into this diagram in different ways, so you can do what makes sense to you.
There is one thing that I would adjust with your diagram. The passage is not saying that the ship sunk normally. It is saying, under normal circumstances, a ship that sunk as rapidly as the Reinzi did (SRR) would have these effects. Maybe that is what you meant, but I just wanted to make sure. Other than that, I think your diagram makes sense.
normally (SRR - - - - -> not WEQ - - - - - > not FF)
