I mean it’s near typical hurricane paths. Back before we could see hurricanes on satellite we were probably much less aware of them; at least insofar as their current size and power and direction.
Could be ships that got hit with a rogue wave, swept crew away? Remaining crew abandoned into lifeboats, possible also wrecked by high seas or just too far out to be rescued/ discovered?
Are there even significantly more shipwrecks described like this or is it like it happened twice in a vast area of the ocean known for huge waves and hurricane activity before we had radar or GOES?
