It’s called Age of Sail, and it looks like a historical blog discussing precisely that.
I came into Age of Sail fiction from the science fiction end of it, actually: reading S.M. Stirling and David Weber got me reading Patrick O’Brian and C.S Forester (I’m currently halfway through A&E’s Horatio Hornblower series, and enjoying it muchly). And then, of course, there’s George MacDonald Fraser’s The Pyrates, which is required reading for anybody who loves old Hollywood swashbucklers (and who doesn’t). So I guess I’m explaining why this is going on the blogroll…
PS: OK, one last one: Naomi Novik. For all your “Napoleonic warfare novels with dragons added; only, and this is really important to note, adding the dragons doesn’t make the whole thing suck horribly, or indeed at all” needs.
