RNLB Abdy Beauclerk (ON 751) was a 41ft 'Aldeburgh' Type Beach Motor[2] which was stationed in the town of Aldeburgh in the English county of Suffolk.

[7] The Abdy Beauclerk arrived in Aldeburgh in December 1931 and was officially launched in May 1932 by Prince Albert, Duke of York.

The Abdy Beauclerk was the first English lifeboat to perform a wartime rescue, which occurred on 10 September 1939, just seven days after the declaration of war.

[9] On 30 May 1940, the Abdy Beauclerk and the Lucy Lavers, which served Aldeburgh's No: 2 Station, were commandeered by the Royal Navy to assist in the Dunkirk evacuation.

[4][11] The Abdy Beauclerk remained on the No:1 station at Aldeburgh until 1959 when she was replaced with a 42 ft Watson-class lifeboat called Alfred and Patience Gottwald (ON 946).

She was renamed Saint Íte and she spent time working as a pilot vessel for Cork Harbour Commissioners, in the Republic of Ireland.
