Repair tactics

[Walruss]

So after 4 hours gameplay, I got sunk.

I was shadowing a convoy out of gibraltar (2 swann class) and I got bounced by an escort. 2 hours worth of dodging and I take a very close hit, flooding the forward torpedo room and quaters. I send men to damage control (incl the engineer with repair quals), order back slow, ended silent running, and try and arrest the dive, and watch the repair times. 3 minutes in the torpedo room is sealed, but the boat is flooding in the bow quaters still and repairs take too long. 30 seconds too long actually, despite the fact that I was actually finally on my way up (the boat survived to 263 meters!! ). Why did I die? Well at 177 meters the quaters flooded completely (despite 30 seconds left to fix it) and the game ended.

Now surely a compartment would not flood like that? A leak that takes 4min 30 to fix does not take 4 min to fill a compartment?

HOw do you guys deal with this? Is there a mod to make damage more realistic?
