Those are on my list, at the moment I am still in the process of collecting all the Sharpe books. I have about 10 of them so far and they are definitely on my "To Be Read" list.
N a M Rodger : Wooden World isn't one of the non-fiction that I've read so i'll definitely take a look at it. Your husband might enjoy Jack Tar - The extraordinary Lives of Ordinary Seamen in Nelson's Navy - Lesley Adkins : Jack Tar: Life in Nelson's Navy
If you wish to drive yourself barking mad, try John's Nautical Fiction List, a vast bibliography of nautical series. It apparently hasn't been updated since 1999, but contains lots of old series that I'd never heard of. It's at: http://intersail.torresen.com/link_in_frame.php?link=607 There's also a good non-fiction list that's part of the same site.
It's time you got acquainted with Patrick O'Brian. He's brilliant -- the Aubrey Maturin Series. All 20 or so of the novels are stand alone but I'd start with Captain & Commander or whatever the first one is.
I actually just got the last P O'brian novel in a swap today, so now that the series is complete it's on my to be read shelf. Actually it has so many books it IS my to be read shelf. :)
