Rhyl, Flintshire. At 10.15 on the night of the 1st April, 1961, the coastguard informed the honorary secretary that a speed boat with five persons aboard, which had left Rhyl that morning, had not returned. At 10.20 a report was received that the speed boat was last seen inside West Hoyle. At 10.47, when the life-boat Anthony Robert Marshall was launched, there was a light south- westerly breeze. It was one hour before high water. The life-boat carried out a search and, with the aid of her search- light and parachute flares, found the speed boat at 11.40. The life-boat took on board her crew of five and towed the boat to Rhyl, arriving at 1.10 in the morning..
