Scientists baffled by orcas ramming sailing boats near Spain and Portugal

• News & Highlights

Scientists have been left baffled by incidents of orcas ramming sailing boats along the Spanish and Portuguese coasts.

In the last two months, from southern to northern Spain, sailors have sent distress calls after worrying encounters. Two boats lost part of their rudders, at least one crew member suffered bruising from the impact of the ramming, and several boats sustained serious damage.

The latest incident occurred on Friday afternoon just off A Coruña, on the northern coast of Spain. Halcyon Yachts was taking a 36ft boat to the UK when an orca rammed its stern at least 15 times, according to Pete Green, the company’s managing director. The boat lost steering and was towed into port to assess damage.
