It has now transpired that there were two orca ‘attacks’ in the early morning of Sunday July 31 near Sines. One, as we have already written, ended with the sinking of a boat and the rescuing of five crew members (now understood to have been all from the same family). The second one involved a smaller sailing boat, en-route from Lisbon to the Algarve, with two men on board. Explains Correio da Manhã today, the men were both asleep when the killer whales hit the boat with some considerable impact, biting the rudder and immobilising it. The boat was later towed to dry dock, as concern among the sailing fraternity about these incidents is rising.
