The 1745 Establishment was the third and final formal establishment of dimensions for ships to be built for the Royal Navy. It completely superseded the previous 1719 Establishment, which had subsequently been modified in 1733 and again in 1741 (but not formally replaced on either occasion). Although partially intended to correct the problems of the ships built to the earlier Establishments, the ships of the 1745 Establishment proved just as unsatisfactory, and important changes in the make-up of the Admiralty and Navy Boards finally led to the end of the establishment era by around 1751.^[1]
