As an avid collector of history books, I've finally found a thread where I can make some useful additions!
I would suggest anyone interested in warship design give a look at the books of David. K. Brown, (1928-2008), who was a noted British naval architect and author. Many of his books will list the author as D. K. Brown. Here is a Wikipedia page about him, listing his books. I have most of his books and thankfully a number of them are available as Kindle versions at quite reasonable prices. I have many of the Norman Friedman books and I'd say that books authored by Brown are more readable as Brown is more of a storyteller. However, they are still very technical (in a good way!) since Brown, being a naval architect himself, is mostly focused on ship designs as well as the historic development of technologies. For instance, the pages on ship stability for WW2 warships in Nelson to Vanguard: Warship Design 1923-1945 is one of the best discussions I've read on the subject.
