In the video, the group of five orcas are filmed following the boat and then ramming into the back of it.

Sailor Phep Philouceros, told SWNS: “The rudder was destroyed in one minute and pulled out”.

It is reported that a rescue boat came to his aid within 15 minutes but “the orcas continued to ram his yacht for another half an hour as it was being towed back to the port of Sagres”.

According to Insider: “Philouceros, who encountered such an attack for the first time, thinks the orcas were young."They were about six or seven meters long. They were neither adults nor babies. If the orcas really wanted to sink the boat, they could have done it easily. I don't think it was their intention," the sailor said".
