Since bat rays are supposedly limited to the West Coast Pacific waters between Oregon & the Gulf of California, and also the Galápagos Islands, I'm wondering if what you are seeing are not really Manta rays. Their "wings" can span up to 23 feet in length. The furthest from the equator they have been recorded is North Carolina in the United States.

Sounds like that would be them. Enormous things and they seem to be in mile wide formation always swimming parallel to the coastline and about 3 miles offshore. I only see them headed north from south. I have never seen them going south.

Last I checked, Monterey Bay is among the “West Coast Pacific waters between Oregon & the Gulf of California.”
