 The changes agreed mainly affected the 90, 80 and 60-gun ships, although changes were made to the draughts of all sizes of ships.By 1752, it was felt necessary to petition the Council for further alterations to be made to the designs, and again in 1754.On this occasion, the Admiralty decided to omit certain details—namely a increase in the length of the 70-gun ships—from their proposals, so as to better the chances of their being accepted.
