Kept the HP tweak seperate as a module, expecting other mods to change the ships' .zon files at some point. The difference between the "full" and "light" version is strictly sinking times.
I might split the HP tweak into a "regular" and "hardcore" version, with the latter increasing the HP to such an extent that you are forced to sink by flooding. Don't think it would be that popular, but it might interest the realism fans.
Thank you for the compliment, and the feedback. Good point on triggering the pyrotechnics while shelling; had only considered torpedo damage to be honest.
