I dearly love the Hornblower novels and the folks at TFL, but I'm puzzled by Indefatigable's classifications in the scenario.
Indefatigable started out life as a conventional 64-gun two-decker.
She was razeed to a 38 gun frigate in 1794
[UD 26 x 24lbr] + [QD 8 x 12lbr] +[FC 4 x 12lbr]
Her armament was upgraded to 44 guns in Dec 1794 by
addition of [QD 4 x 24lbr carr] + [FC 2 x 42lbr carr]
and again increased in Feb 1795 by further addition of
[QD 2 x 12lbr]
(Robert Gardiner "Frigates of the Napoleonic Wars")
Her measured tonnage was 1384t (a 32=gun frigate would have been < 1000t.
No desire to cause any strife, just curious.
Best wishes for Boxing Day everywhere it will be celebrated tomorrow.
