"Orcas disrupt boat race near Spain in latest display of dangerous, puzzling behavior"As per the article:
"A pod of killer whales bumped one of the boats in an endurance sailing race as it approached the Strait of Gibraltar, the latest encounter in what researchers say is a growing trend of sometimes-aggressive interactions with Iberian orcas.
The 15-minute run-in with at least three of the giant mammals forced the crew competing in The Ocean Race on Thursday to drop its sails and raise a clatter in an attempt to scare the approaching orcas off. No one was injured, but Team JAJO skipper Jelmer van Beek said in a video posted on The Ocean Race website that it was “a scary moment.”"
Further in the article:
"Scientists have noted increasing reports of orcas, which average from 16-21 feet (5-6½ meters) and weigh more than 8,000 pounds (3,600 kilograms), bumping or damaging boats off the western coast of the Iberian Peninsula in the past four years.
The behavior defies easy explanation. A team of marine life researchers who study killer whales off Spain and Portugal has identified 15 individual orcas involved in the encounters — 13 of them young, supporting the hypothesis that they are playing. The fact that two are adults could support the competing and more sensational theory that they are responding to some traumatic event with a boat."
A second, hyperlinked article titled,
"Killer whales damage boats in Spanish, Portuguese waters in puzzling new behavior," reports:
"BARCELONA, Spain (AP) — A pod of killer whales repeatedly rammed a yacht in the Strait of Gibraltar this week, damaging it enough to require Spanish rescuers to come to the aid of its four crew members.
It was the latest episode in a perplexing trend in the behavior of orcas populating the Atlantic coast of the Iberian Peninsula that has left researchers searching for a cause."
Further in the hyperlinked article:
"Biologist Alfredo López, of the University of Aveiro and member of the research group, said that the incidents are rare — and enticingly odd.
“In none of the cases that we have been able to see on video have we witnessed any behavior that could be considered aggressive,” López told The Associated Press by phone on Friday. “They appear calm, nothing at all like when they are on the hunt.”"
I know nothing about orca behavior. But, compared to the high number of relatively fast, massive ships with noisy propellers continuously passing through the Strait of Gibraltar, a slow, quiet sailboat might appear to be a safe novelty to them. If so, their behavior might be driven by playful curiosity.
