At 7.39 p.m. on 7th June, 1966, a message was received that two boys had fallen over the cliff at South Stack and that it was doubtful if the coastguards would be able to reach them. The lifeboat St. Cybi (Civil Service No. p) was launched at 7.49 in a gentle south south easterly wind and a slight sea. It was one hour before low water. The life-boat, with the boarding boat in tow, proceeded to the position, and found the two boys at the bottom of the cliff. They were taken off in the boarding boat and transferred to the life-boat, which returned to her station at 9.40. A helicopter stood by while the rescue was carried out..
