Torpedo/sinking realism?

[EnDSchultz]

My first post on the forums is a stupid n00b question! Yay!

Anyway, I've been enjoying SH4 and soaking up a lot of mods off the site here, but I haven't seen one that alters the sinking mechanics to be more flooding-based like GWX3. Well, I did see one, but the reviews it had weren't very promising. Anyone charitable enough to point me to a good one, if such a mod exists? I'm getting a bit annoyed with always needing to blast a merchant with a salvo of torpedoes to sink it...
