 These establishments had left the actual design of each vessel to the Master Shipwright in each Naval Dockyard, with the Surveyor of the Navy responsible only for common designs for those ships built by contract by mercantile shipbuilders.However, under the new 1745 Establishment the responsibility for preparing designs ("draughts") for all ships was given to the Surveyor of the Navy, with the Master Shipwrights now responsible only for constructing ships to those common Surveyor's designs for each vessel type.Additionally, control over the Establishments was passed from the Admiralty to the Privy Council, a move intended to remove the possibility of ongoing change.
