That list would be nowhere near complete.

For example my brother lost a vessel in a hurricane - he was bunkered down on the mainland and it was gone after the storm - we assume the storm surge lifted the anchor off the seafloor and it floated to who knows where and wrecked.

It wasn't insured, so wasn't reported. I suppose it's possible someone stole it, but I can't imagine anyone would be brave/stupid enough to do that during a hurricane.

Maybe someone somewhere in the world got lucky enough to see a drifting abandoned vessel and claimed it... but that's pretty unlikely.
