Alexander Kent's Bolitho Series
This excellent series of novels on the war at sea in both the War of the American Revolution and the French Revolutionary and Napoleonic Wars is highly recommended.
I have found it to be superior to the Hornblower novels.
I first read the Bolitho series in college and have recently begun them once again, finding things that I didn't recall immediately. It's a great series and I'm still reading through them.

If you are looking for a good historical fiction series (not our era) try John Biggins' "Otto Prohaska series". First book is "A Sailor of Austria", it starts a little slow, but is well-worth reading.
