On the short term, I think Ill have a look at the torpedo radius and normalize the damage a bit. With less variable damage (it really varies a lot) the effect is a little more predictable, and by increasing the radius it affects more compartments (at least potentially). With torpedoes more likely to puncture 2 or even 3 compartments, I can back off the flotation settings a bit, which imho are rather extreme in some cases (can be as much as 5 times higher than stock).
Should result in more spread-out damage, and a more natural look. More widespread damage to make it sink more naturally, compared to focused and exaggerated damage. Should also make for listing and possibly capsizing to appear, either naturally or with a little more tweaking.
Nice work on the crew balancing btw, imho changes like that are essential to a better and more realistic/balanced game.
