Ok, since this got bumped already (Not me this time! I swear!!), I don't feel so guilty asking this. Reading the thread, this question popped into my head. And it actually may reinforce the apples vs oranges arguement.
Would density of the water affect the crush depth?
Modern ships have that density tree painted on the side of their hulls, indicating max load for a given body of water. Fresh water (great lakes, etc) had a lower density since they were fresh water, and merchants can safely hold less cargo than a tropical Ocean, since the salinity is higher.
How would this affect Subs? Would the Germans/British have a shallower crush depth since their water is more 'dense', and the Americans/Japanese have a greater depth? Not sure on where the Med rates, but that's the Italians.
Or is it a moot point since the difference would be so small that individual boat factors (welds, age, damage, etc) would affect it first?
