Floating Dry Dock for copies of actual WWII Blueprints
Each boat was individual in it's details and each yard had different designs, fairwaters would change or be modified through out the career of the boat.
Forgot to mention that the emergency marker buoys on the model are POST War, they should be round and in some cases in different locations depending on the boat, many just had plates welded over the openings, also the broom needs to be removed from the mast.
Also depending on the boat the decking may be different, some had all wood decking where others had plate with wood around the fairwater (like the model has)
Rokket's site has some good information on the decking and other features of the boats.
The base model will give you enough for Electric Boat and Manitowic built boats without having to redo the side openings, or move the anchor to the port side.
