Plymouth, Devon - At 3.50 a.m. on 16th July, 1966, a converted ship's lifeboat with four men on board was stated to be overdue. The occupants had gone fishing at the ledges nine miles out. The life-boat Thomas Forehead and Mary Rowse left her moorings at 4.15 in a gentle north-westerly wind and a smooth sea. It was half an hour before high water. She found the casualty - it had engine trouble - at 4.30 half a mile south of the Bridge buoy. The life-boat towed the boat to Plymouth, and returned to her station at 5.30..
