Argh... This is just too much for me, I'm getting too nervous.
This game seems to lack gravity where there should be more, and there is too much gravity where it shouldn't be!

What I started with was modyfing subs mass and displacement to historical values (as goblin editor says, both values are 'tonnes'). But then the sub is acting like a tank, both pitch and roll does not exist. So I had both mass and displacement set to half of the historical value. There was a shadow of effect. I changed the gravity center to 0.4 (I found materials regarding XXI type u-boat compartment masses, and counted about where it had its mass center). It gave a small effect too. With LR drag for surfaced boat set to 0.9 the boat does give a fair amount of roll... BUT only when turning. When going straight - it gives a slight roll but it has too big frequency.

Pitch... First I set the surfaced draught parameter to 5.0 to get the sub a little deeper in the water... With that I was satisfied, till I saw what happens on heavy sea... Disaster, that's what it is. Changing the seaparameters.cfg gives a little effect too. Crappy look, when the wave passes the boat and it still goes perfectly straight.

I'm just tired with this for today. There must be another way to get this right, I wanna see my u-boat rocking on the heavy seas.

One thing though I am happy with... When you change the gravity center to something about 0.4, when you blow your ballast for emergency surface, the boat nicely jumps out of the water. It looks quite like in The Hunt For The Red October (of course it's far from the angle they got when surfacing, but for a moment you can see the diveplanes)

I hope someone deals with this soon, I'll definately try, but I doubt I'll succeed.

EDIT: what BumpScaleU and BumpScaleV stands for? For me changing this values gave weird effects...
