I am by far not an expert and I know little but I am just guessing.

Correct so far.

Boats behaviour under water is affected by many things

- water density and temperature - affects the amount of water to flood the tanks for a designated depth

- fuel and food consumption over the last day - it affects the weight

Chief engineer has to watch all these things and has to calibrate the boat every day. It´s all a matter of mathematics

If the boat is trimmed wrong you´ll stay too long on the surface or go deep much too fast.

I'd add that if the boat isn't trimmed properly it can be "heavy" on the bow or on the stern and thus very difficult to sail underwater

Right, thanks
