David Smith, who had a “terrifying” encounter with an orca in Portugal in October 2020, told the BBC: “I don’t frighten easily and this was terrifying.
“I looked at this animal and it was jet black and brilliant white. It was continuous. I think there were six or seven animals, but it seemed like the juvenile ones, the smaller ones, were most active.
“They seemed to be going for the rudder, the wheel would just start spinning really fast every time there was an impact.”
In the incidents in 2020, the killer whales approached boats and bashed into them in frightening encounters.
