The ports files can be modded?? (good news-I now have another idea for a small project containing a lot of work for a small return--my specialilty:rotfl: )
If so, I suppose you could dock at port after the St. Nazerie raid--replace the "La_Rochelle" port file (used for st, nazerie) in the locations file with a "modified damaged "La_rochelle" file from 03/29/42 on for a few months of game time then change the port file in locations back to the stock file to simulate the damage and subsequent repair
