There are 19 free high definition plans of the
Ardent 1764, 1782, and 1796 on the WikiCommons site.

The
Indefatigable (launched in 1784 and commissioned in 1794) was part of the
Ardent (64) 1764 class with included
Nassau 1785
, Agamemnon, 1782
, and others so maybe better to use the drawings for Ardent 1764 rather than the drawings of
Ardent 1782. Or download all of them and compare them. There are some differences including a coal hole on the 1782 version and the location of the stations on the keel are a little different. With the wide spread of years for the
Ardent 1764 class there may also be some confusion as
Ardent 1764 was renamed
Tiger in 1783 even before
Indy of the
Ardent class was launched in 1784. In any case I think it is safe to say that the high resolution drawings of
Ardent 1764 will be appropriate for
Indefatigable 1784. You may want to search the National Archives in Kew to see if they have a contract for
Ardent 1764 or possibly
Indefatigable. There may be one for
Agamemnon at Buckler's Hard where she was built as well. (There is a contract for
Ardent 1782 at RMG but may not be applicable in all respects.) There is also a contract at RMG for the
Nassau 1785 dated 18 December 1782 which was part of the
Ardent 1764 class so probably very useful. You can also use the
Shipbuilder's Repository for scantlings as well, as they should be very close. These can be found in the original book on-line for about $400 or in
The Scantlings of Royal Navy Ships which includes the scantlings from the Establishments 1719-1750,
The Shipbuilder's Repository and Steel's
Elements and Practice of Naval Architecture available at Seawatch Books for $45. I have two extra copies if you are interested.
I for one look forward to your build!
