I agree with jscharpf. I think it's unrealistic when 2 torpedoes are necessary to sink a vulgar freighter !
But it's also unrealistic when a battleship is destroyed by one or two shells fired by another battleship !!!
I would like to find a solution to this problem. I've tried to set the Yamato's FlotabilityGenB's armor level to 125 : well it is much stronger, but also unsinkable with torpedoes !!
Does anyone know what's the formula to calculate the number of hitpoints lost by a **** when it is hit ?

There are several parameters but i don't know how it works :
- the shells : are there values for each different type of shell ?
- the .zon files of each ship :
- types of boxes (FlotabilityShow, NFlotShow, FlotabilityUpper : what does that mean ?)
- armor level of boxes (what means the value "-1" ?)
- the zones.cfg file (in data file) :
- multiplier
- flotability
- hitPoints
- destructible
- armor level
- critic flotation
- critical
- critical chance
... i'm completely lost !! help please !
