What IS the subject of this thread?
Plans and diagrams are available and so why are you using artistic drawings and etchings, many by artists who did not see what was happening or saw it from a distance - or at night - and drew it later. To produce plans you claim are NOT of those vessels? Is it to interpret those drawings and etchings?
For those wondering what I am on about, here is a photograph of people watching a bombardment.
USS New Ironsides, bombarding Fort Moultrie Charleston, South Carolina. April 1863 and the published version:

This was one of the few photos found using '
civil war ironclads bombarding' image search. There is little detail to be seen and a sketch artist would need a telescope or opera glasses to get any detail. Most of the results of that search are wood engravings from etchings drawings which use a certain amount of 'artistic licence' - the only images that could be produced in illustrated productions like this one from Harpers Weekly.
