Here are some non-fiction books that would, I think, be good for the general gamer who wants to dive more into this era. None of these are as technical (or expensive) as Harland's "Seamanship."
General:
HMS Victory Owners’ Workshop Manual. Haynes Publishing. Ignoring some of the gift-shop photo book style, this actually includes a reasonable amount of detail for those who don’t know much about the era but want an intro suitable for Naval Action. Includes some schematics, armament, mast and spar names, steps for tacking and wearing a square rigger.
(If you want schematic drawings of every deck, hull cross-sections, list of guns by year, and fewer photos, then John McKay’s Anatomy of the the Ship Victory (with foldout plans!) is a better book. Don’t be fooled -- the cover makes it look like a children’s book, but I used it as my map & reference when I visited the Victory in Portsmouth.)
Battles
Sea Battles in Close-Up: The Age of Nelson David Lyon Summary of the history and ship movements in several key battles.
Nelson’s Trafalgar Roy Adkins Detailed layman’s history of the context and the battle itself.
General History:
Six Frigates Ian W. Toll (History of the first significant ships in the US Navy)
The Billy Ruffin: Biography of the English ship of the line Bellerophon David Cordingly
