“I know that the discoverers want to keep it hidden as a gravesite but I wonder if it could actually be raised since it is in such good condition.”
It was done back in the 60’s with a vessel that capsized in Green Bay in the 1860s named the Alvin Clark. When raised, she actually floated into port on her own(after being pumped out).
Unfortunately, there was no real preservation plan, she deteriorated, and was broken up a few years ago. If they had left her in place, she’d still be there.
