This picture shows M33 HMS Brocklebury passing Burhou I on her way down the Sound of Mull yesterday afternoon at about 3.00pm. She seemed to hesitate, then turned into Tobermory. Perhaps the crew had heard that the Mull Festival was in full swing, and felt like some light relief after the hard work of the Joint Warrior exercise.
Built in 1987, Astor is owned and operated by German companies. There's more about her here.
