RL subs at PD in heavy weather

Hello!

Two q's:

In the real war diary of U505 I found it writen the boat was able to dive to "A+20m" because one of its torpedo tubes couldn't be closed tight. This lead me to think, why they used the letter A? I assume "A" means the "zero line" = 0 meters. The other possibility is "A" means the keels depth = about 5 meters. Does anyone know the right answer and what was the reason to use a letter?

If the "A" means the zero line, the surface, where does it actually lies if there is a heavy weather? I mean, the "zero line" is movig up and down all the time, so practicaly there is not such a thing like "zero line" actually.
The reason why I'm thinking this "philosophy" is that I wonder, how the rough weather affects for DOOW's actions? If the wave height is let's say 6 - 8 meters, it have to mean the captain can't just give an order: "Make your depth one-three meters", because the boat is unable to follow the motion of the waves. So I assume the boat is driven near surface a bit by bit after the CO's advices, and after the boat has reached the wanted depth, DOOW is just trying to keep the boat in balance.

Does anyone really know if I'm right? Observer for example?

Greetings,
