Orcas Sink tourist yacht

I would say no, the Orcas choose their favorite sailboat and part of that ceremony involves being on the seafloor, Orcas may use enhanced interrogation techniques to encourage the hull to move towards the seafloor but they don't destroy the sailboats.

It is Al Qaeda that is evil and creates these sailboats!

Orcas are on our side on the Global War On Bouyancy.
