Dear Wind, dear Captains,
The draughts are part of a longer thesis on the comparison of Britisch, French, and American 18-pounder-frigates, written by Dirk Böndel, which can be found here (https://depositonce.tu-berlin.de/bitstream/11303/598/1/Dokument_8.pdf),
where the specs of the frigate classes are listed. Unfortunately it is written in German, but there are many plans, drawings, diagrams, and tables.
Cheers
Alan Grey
