Trearddur Bay Lifeboat Station is located in Trearddur, a village and seaside resort overlooking Trearddur Bay, just south of Holyhead, but on the opposite south-west corner of Holy Island, off the north-west coast of Anglesey in Wales.
An Inshore lifeboat station was established at Trearddur in 1967 by the Royal National Lifeboat Institution (RNLI).
The station currently operates both an Inshore lifeboat, Hereford Endeavour (B-847), on station since 2010, and the smaller Inshore lifeboat, Clive and Imelda Rawlings II (D-885), on station since 2024.
In 1964, in response to an increasing amount of water-based leisure activity, the RNLI placed 25 small fast Inshore lifeboats around the country. These were easily launched with just a few people, ideal to respond quickly to local emergencies.
More stations were opened, and in May 1967, a lifeboat station was established at Trearddur Bay. A Inshore lifeboat was placed on station, with her first rescue taking place on 4 June. A boathouse was constructed in 1971.
On 2 September 1971, the Trearddur Bay Inshore Lifeboat was launched to the aid of two men, who were clinging on to their dinghy, which had capsized twice in bad conditions, close to Cod Rocks. Both men were rescued. Helm John Burns and crew member Edmund Williams were each awarded the RNLI Bronze Medal.
A new and larger boathouse was built in 1993, which provided changing room facilities, crew room and galley, a workshop, fuel store and storeroom and a souvenir outlet, which allowed a new lifeboat to be placed on station on 5 December 1996, with the D-class being withdrawn.
On 24 May 2001, the station's Honorary Secretary Mr Jack Abbott was awarded the Royal Humane Society Testimonial Vellum and a Resuscitation Certificate, for his rescue of a man who got into difficulties trying to return to the shore, after swimming after his dinghy which had drifted away from the slipway. Abbott spotted the man face down, from shore and swam out to him, towed him back to shore and performed CPR.
The same year, a decision was made by the RNLI to reallocate a D-class lifeboat to Trearddur Bay to operate alongside the B-class lifeboat already on station.
On 24 February 2011, on their first official engagement as a couple, Prince William and his fiancée Catherine Middleton attended the station, to officially name the new lifeboat Hereford Endeavour (B-847).
In a severe south-westerly force 9 gale on 20 May 2021, the was launched to the aid of a female surfer. The surfer had got into difficulties, and was now in the water, struggling to get ashore. She was dangerously close to the Cod Rocks, and was being continuously forced underwater.
The crew made no hesitation launching into conditions, which were at the operating limits of the lifeboat. Helm Duncan showed extreme seamanship and boat handling skills, bringing the lifeboat just from the rocks, and with precision and good timing, brought the boat to a position, where the crew could quickly retrieve the casualty, whilst ensuring everyone was as safe as possible.
For this service, Lee Duncan was awarded the RNLI Silver Medal. Recognising their contribution and bravery, the three crew members, Dafydd Griffiths, Leigh McCann and Michael Doran were each awarded the RNLI Bronze Medal.
