Rate of Descent

[Catfish]

Hello,
the boats were able to dive very fast, in case they flooded additional "cells", even at low speeds - but they would then need pressured air, to bail (right expression?) those flooded cells again, at the desired depth.

So if you lose more pressured air after a fast dive, than as if you are going deeper dynamically through propulsion and rudder alone, i guess that should be ok.

Greetings,
