The boats underwent several fairwater diets as the war progressed. A lot of it is going to depend on what period you are showing her, and how many times she was on the yard. They tended to trim more and more as the war went on. From what I've seen, she was at Mare Island for overhaul between the sixth and seventh patrols, And lost on her eighth. Her fairwater was undoubtedly cut down, but don't know how far. Also was not uncommon to have minor changes to the fairwater, as well as gun fit done during the 2 week refits between patrols.
To the best of my knowledge, once the ports were gone, they were gone for good.
Sounds like a good project, honoring a boat still on patrol.
