The two gouges were about 15 inches apart, about 3 inches long and went through the gelcoat. He also saw no other markigs or blood spots. Sounds like spinning rotors to me. I amagine the owner of the "UAV", or "UFO" if you like, lost a few bucks that day.
I recall a few bird strikes that did not leave blood spots, so it could have been a bird strike as well.
