In November, 2007, when I visited the USS Yorktown Museum ship at Patriot's Point, SC, I took the opportunity to photograph her extensively. The ship being docked starboard side to the pier (as these ships were specifically designed to do - particularly after additon of the angled flight decks), the best photography, save from a boat on the river, is by far facilitated for the starboard side:

I also moved in to take numerous closeups which, through the magic of PhotoShop®, I blended into a seamless mosaic, shown at right (and displayable at high-resolution). Although excellent for resolving small features, relative sizes and angles are highly distorted in this type of mosaic; composed of shots from relatively close-in.
The closer-in the pics, the more severe the distortion - which is exactly the case for the port side of the island:

Accordingly, my second least-distorted pics are of the island
ends, for which it was possible to back away (about half) the length of the flight deck:

Yorktown-II ended her service as a training carrier (ATV), before which she was an ASW carrier (CVS); if specific details of the SCB-125 Essex islands followed any systematic trends, I would guess the above represents either the ATV, or CVS (or both) fits - with much stripped off, of course. For example, radars and radomes are clearly missing.
However, for basic structural components of these islands - plus quite a bit of piping- and railing detail, etc. - these pics will, it is hoped, be useful.
