Moelfre, Anglesey. At seven o'clock on the evening of the 18th of July, 1959, the coastguard told the honorary secretary that a sailing boat was drifting towards Dulas west of Moelfre.

A watch was kept on the sailing boat.

She did not at first appear to need help, but at 8.30 the coxswain said he was not satisfied with her position, and at nine o'clock the life-boat Watkin Williams was launched. She took a boarding boat in tow. There was a rough sea, and a fresh south-westerly wind was blowing with a flood tide. The life-boat found a catamaran with four people on board. She had a broken rudder and torn mainsail and was among rocks close inshore. With the help of the boarding boat the four people were transferred to the life-boat, and two of the life- boat's crew were put aboard the catamaran. The life-boat towed the catamaran to Traeth Bychan beach, where the survivors were landed. She then returned to her station, arriving at 10.30. The rescued people made a donation to the Institution's funds.

Rewards to the crew, £6 ; rewards to the helpers on shore, £3 5s..
