Scientists baffled by orcas ramming sailing boats Portugal

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

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. Researchers who study a small population in the Strait of Gibraltar say they are curious and it is normal for them to follow a boat closely, even to interact with the rudder, but never with the force suggested here.
