I am trying to formulate a couple of scenarios using card model ships using the USS Mannert L. Abele (DD-733) at Okinowa for one scenario and the USS Lexington (CV-2) at Coral Sea in another. However I am confused over how much the structural damage each ship can take. I do see some examples were the Akagai has 70 points (37,100 tons standard), while the Enterprise has 30 points (19,800 tons standard). I cannot find any example of calculations for ship damage in the forums. I would suspect the damage rating is based on ship tonnage. Can any one point me in the right direction so I can find my answers?
