2) Left the longitudinal position of the cg alone
3) changed the surface draught from 5.75, to 4.75
4) In the sub cfg file changed surface depth to 4.

These changes have resulted in some really good roll characteristics, in stormy conditions, or during heavy surface maneuvers in calm weather.

On calm waters the boat does not bob as bad, and slices through the water nicely. When maneuvers at flank speed are performed the boat will lean into the turn. This is the case under water as well.

In 15 knot wind the pitch is close to perfect. With the CG set at 3.0, the boat will roll really far every now and then. My experience is that it reaches the limit of what the camera can handle which results in an undesirable "popping up" effect. This will sometimes require the use of shift U, to get you back on deck.

If any one can figure out how to remove this problem, we can possibly have the boat lean further. The roll is not have high rates, it is slow roll, like that of a heavy boat like a sub.

(note: This changes were done on the mod of this thread. If you try to apply a CG height of more than 2.5, on the unmodded subs, the boat will capsize even in calm water.)

This mod is great, and with these changes it is wayyyyy better than stock.

I did it on all, and am in the process of testing all.

I just get tired of having to reload the whole game in order to test minute changes.

I have got the a to be surfaced at the light gray water line in still waters, in 5 meter per second wind it wants to dip lower.

I am just fiddling with stuff for now.

If you want to ddrgn, you may add those tweaks to your mod.

I hesitated posting the mod under my name, since the displacement and other sub behaviors were ddrgn's doing. I just tweaked the surfaced draught, and CG height.

For all I know the VIIA may behave beautifully, and the VIIC/41 will happily flip over when put into a crash dive.

I will mess with this stuff more this evening, and keep you all up to date.

The details are all in my description. Really simple honestly.

I am noticing the VIIA, is having some roll instability in 4 MPS winds, and it seems to bob quite a bit. I may lower the CG .02 meters to see how that works. I don't like feeling I am in a bath tub toy. LOL So with that there is still some work to be done. This is happening with the boat in the campaign (new campaign since my old one got buggered by the patch.)

Some fun reading about the VIIA, in real life they had bad depth keeping properties....just like our Sh5 model does. That is kinda cool the devs kept that in mind. Or perhaps when you put in the historically accurate figures, we get an unstable boat.

For the person with the observation problems. Surface your boat and fully extend both scopes. Your problem will be glaringly obvious.

The eyepiece of the observation scope was in the control room, whereas the attack scope eye piece was a good couple of meters higher in the conning tower.

So at depths your attack scope is skimming the surface, the fully extended observation scope in at least 2 meters below the surface. This is acurate seeing as the scopes were equal length.

That and I think it's running too low, my decks are awash too often I think.

VIIA never gets up to 5m anymore with this mod, so you're constantly "decks awash". Here I am trying to use the deck gun with my new campaign and the VIIA:



:03: Granted, if I were to slow down a bit it wouldn't be that bad, but it was still pretty funny when I brought up the sights and totally lost track of my target!
