For the last several years, we have been posting about orca attacks on yachts and fishing boats in the Strait of Gibraltar and the Iberian peninsula. Pods of orcas have been ramming sailboats and often grabbing their rudders and keels, and have caused significant damage, most often to the boat’s steering. In the last three years, there have been close o 500 such attacks and at least three sailboats have been sunk.
What has prompted the attacks remains a mystery to scientists.
Until recently, the attacks were confined to the coastal waters of Spain and Portugal. Now, the Guardian reports that an orca repeatedly rammed a yacht in the North Sea off Shetland earlier this month.
