For the last couple of years orcas have been ramming and breaking the rudders of small boats off the coasts of Spain and Portugal. They've actually figured out that without a rudder a boat stops moving, that's pretty forking impressive. They sunk at least one (but didn't attack the lifeboat). Hundreds of these events have happened, it's now a known hazard in the area and boats are advised to avoid the area if they can.
