Mod to make sinking realistic?

[Rancor260]

Alright i'm new to the forums and from a quick glance i couldn't find a mod that makes sinking times and sinking realistic based on flooding... what i mean is that when a ship is shot by torpedo it should create a lot of flooding even enough for ship to completely sink given enough time, this is not how it works in unmodded sh4 afaik. I know some mods like RFB make it realistic but i'm not looking for a mod that changes the game completely just a little mod that makes sinking realistic.

Sorry about my bad english, hopefully people understand what i'm trying to say here

EDIT: I tried RFB and i can already tell that mod is not for me. The only thing i was able to sink was a fishing boat... i tried to sink one medium sized merchant ship for about 1 hour and no sinking at all even with a multiple shots below waterline... I didn't use a torpedo though (because the ship was relatively small and had no guns) so i don't know how effective torpedoes are in RFB but anyway realistic or not that is way too hard and time consuming for my taste. I just want the ships to sink naturally if you shoot them below the waterline instead of always exploding for no reason and then sinking in 10 seconds.
