Troon, Ayrshire. At 7.55 on the evening of the 2nd June, 1961,during an exercise launch of the life-boat James and Barbara Ait ken it was noticed that a catamaran had lost its sails and was in difficulties, with a crew of two, three- quarters of a mile north of Troon. At the time there were light westerly airs with a slight sea. It was two hours before low water. The life-boat towed the cata- maran into Troon harbour and returned to her station at 8.40..
