There was a boat salvage yard in Georgia that was shown on a YouTube video by the Born Again Boating channel. That place was huge!
It's a long video and I'm not sure on the exact location or contact info, but it appears that quite a few of the comments listed under the video are from someone who works there.
Might be worth trying to reach out to them.
