Yeah, I tried playing with the mod but indeed, when the weather is bad they're just standing there with their shirts like we're already sailing from Penang lol.
It didn't feel realistic enough for me so that mod has gotta go then.
Also, I guess you're right, it's much easier to fire a gun from a large steady ship than from a rocking and rolling U-boat. Didn't think of that. So now I can't fire my guns in a storm, but at least this explanation took my frustration away
