Im talking about looking for a quick and easy way for making them a tiny bit harder to sink (preferby) or tinsy bit harder to blow up. That way it requirse a bit more ordinance per ship, and i sink less tonnage.
While im not normally one to look for spot on historical accuracy in all things, i firmly beleive that tonnage success should be measured in 10,000's of tons instead of 100',000's of tons. The contradiction here is i dont want realistic sinking times.
