I'm sure their are all sorts of threads relating to this but a few others books i would recommend.... not free unfortunately but all available on kindle:
The Admiral Benbow by Sam Willis is a great read on the early age of sale
The Fighting Temeraire again by Sam Willis is a fascinating look into the life of the first 2 ships to bear the name Temeraire and how they relate to Turners famous painting
Very similar to The Fighting Temeraire is Billy Ruffian by David Cordington. I read the two one after the other and unfortunately they are a bit too similar. I prefered the latter but both are worth a read.
"Commander" by Stephen Taylor is a biography of Edward Pellew and worth a look BUT another book i preferred by Stephen Taylor again heavily featuring Pellew is Storm on conquest, specifically about the war in the Indian ocean.
Sam Willis again.... this time The Glorious First of June, a in depth look at this specific battle and the early revolutionary war at sea.
Hearts of oak and souls of fire is a broad look at the entire naval war but is a bit spare on details, read it on holiday and it was pleasantly distracting, Ed Kernahan.
If you enjoy "The fighting Temeraire" and "Billy Ruffian" you can try HMS Amphion 1798 by Michael Feather which is a good look at the frigate war.
Possibly the best read i can recommend on this subject, but not specific to the naval war, is "The War of Wars" by Robert Harvey read it cover to cover a couple of times despite being a vast book. Covers a lot of subjects but the chapters on Sir Sydney Smith and Thomas Cochrane inspired me to do a lot more reading on these men.
Finally honorable mentions to "Overlooked Hero: a portrait of Sir Sydney Smith" and "Nelson, The Sword of Albion" but whilst there good reads they are little better than a dozen over biographies on these men.
You could also look at "The Men Who lost AMERICA" by Andrew O'Shaughnessy but again this only touches on the Naval war and focuses more on the land aspects of the American revolution.
