Cool topic mates!
I gotta say: I read some books lately and there were some pics of a VIIc that made me think it was dead, but i was stated that the Inner pressure body of the sub was intact while the rest of the Boot seemed like blown away! It was DC'ed into Oblivion...But...it still was working, and returned save home. Only the outter hull got hammered away!
This makes clear how strong that inner hull was.
And it was stated that the weakest part of a Boot were the joints of the pipes (flanschen) that went tru' the sub and connected the inner hull with the outter. One of the most common "minnor" floodings occured through the joints and pappenberg's glass-stand!
As for "Das Boot" not being a source for realism: Well it's damn close seeing how the Kaleun that Prochnow potrayed was there at the shooting and added his two cents.
But back on Topic, since our fav. sim does simulate this only with HP's the only thing we can do is to fin a work-around or a compromise!-
Like Teddy stated, the model we have in NYGM may be exciting, and like the name says "hollywood" but far from perfect. :hmm:
Sorry long rant!
