I mean, how do you even research a 1500 era hurricane and ship track much less actually finding anything.
mind boggling...they deserve every penny for the amount of work it takes.
I belive there is a beach in South Carolina where an old shipwreck (long ago broken up and crumbled but near the coastline) “leaks” its treasure after every hurricane and storm.
You can see a small army of treasure hunters, with metal detectors, combing the beaches for coins, artifacts and jewelry. Items are found every year.
IIRC, Mel Fisher researched government archives in Spain that provided clues to locating the Atocha.
