Thanks Richard, point well taken

There is the contract for the sister ship
Aurora that I transcribed some years ago. I don't recall if the original is at RMG or if it is held at the NA in Kew.
There are 10 drawings of the
Enterprize and her class which includes
Aurora. If you are looking only for
Aurora, be careful which plans you use. The
Enterprize drawings include her plans as a fighting ship as well as when later de-masted and anchored at the Tower of London. There she was a receiving ship for foreign ships, then used to hold impressed citizens that were then taken to assigned ships. The drawings can be found at the RMG Collections website in low resolution or can be purchased from them in high resolution. Some of them can be found in high resolution on the Wiki Commons site for RMG drawings on page 8 .
