just recently i realised this too.
choppy sea, at 15ms, is praticly a shield to almost everything the allies can throw at you, surface vessel wise.
no destroyer can get a decent fix on me. if im detected, i can simply dive away, without using silent run or anything. they will never get more than one run at me.
after reading uboat killer by donald macintyre, i think that its quite well done. the book states how hard it was for the escorts to sail, yet combat an uboat, in very bad weather with high seas.
the prob is, that 15ms should be a weather extreme, but as the weather system works, it seems to be the standart "bad weather mode". i had my recent patrol completed. nov-okt 44 arpoud the british isles, and i had the 15ms, plus various stages of rain and fog, for the whole patrol. not a single notable improvement.
the second prob is that the same general diffcultys, should be applied fo rthe uboat. navigating, keeping depth, sitiuational awareness, collecting a firing solution, or even firing a torpedo straight, should be a hard, to impossible thing. i think it was a. werner, who stated in iron coffins, that a uboat would not risk to attack in very bad weather, since it was useless anyway.
