Thanks for lookin up that info. I got a reply from HansSolo 78 about WAC and he says it uses the same model as the stock game. Which is hit point based. I did also get out the GWX manual later today and read what you posted. I find this model very realistic and satisfying. Some sinkings occur a looonnng time after a hit because of continuous flooding, heavy seas or a critical itnternal explosion.
Here's hoping SH5 uses a similar or even more advanced system!
