Another question, does anyone have an image of the stand compass on an US WWI era battleship? I assume the same stand compass would be carried through WWII on older battleships.

During 1942 Refit Pennsylvania’s prominent Midship boat cranes were removed and replaced by a pair of simple booms stepped behind the new aft superstructure to handle the remaining 26 foot whalers. Unlike the crane it replaced, it looks like the booms had no integral machinery whatsoever. It was simply a long tube pivoted on the deck at one end, and handed by tackles affixed to the other end. There seems to be tackles for raising and lowering the boom, swinging the boom, and raising the lowering the hoisting hook.

The tackles seems to not be permanently attached to any machinery either. They seem to normally be belayed somewhere. When they are used, they are either pulled by hand or are wrapped around a new Drum winch Installed ahead of the 40mm bofor tub.

Does anyone have photos of where these tackles are belayed to when stowed?

Also, I suspect the arrangement of tackles on the boom is largely standard. Is there any diagrams showing how such booms are typically rigged aboard WWII era USN ships?

I quoted my own message because in the original post, for some reason parts of the message I posed did not show up.

FYI - this may have already been posted, but it seems NARA has digitized the microfilm rolls for BB-38 and BB-39 hull plans and made them available on the Archives.gov website:

she had another much larger refit at Mare Island sometime between Midway and august 1942. the aft tripod was removed and replaced with a new stub superstructure. the aft director was removed from the tripp’s and set atop the new stub superstructure. the open single mount 5”/25 were replaced by twin 5”/38 turrets. the 5”/57 casemates were replaced by handling rooms for the new 5”/38, and the twin cranes were removed, their role taken by the afore mentioned booms.

Thanks Ian!! These links (to the plans) compliment the ones I found at NARA in 2016 which show her 1935 rebuild and will come in handy when I begin my PENNSY build in the near future!

Some photos from NARA II, courtesy of James Noblin, of Pennsy after her late 1942/early Jan 43 refit/rebuild. I've cropped most of them down to highlight the area you are interested in.
