Welcome to the Chart Room - a resource for maps, atlases, charts and diagrams relating to the Aubrey/Maturin series of Patrick O'Brian.
The Voyages of Jack and Stephen laid out in marvelous detail (with pictures) at Tom Horn's Patrick O'Brian Mapping Project
Great maps of the Nutmeg of Consolation at Kerry Webb's site
Greenwood's 1827 Map of London - a marvelous web map that will show you London in as much or as little detail as you like - look for the Admiralty in Whitehall
Online Maps of Great Britain - an interactive site that lets you enter place names and then shows a map of that location (unfortunately Shelmerston, Ash Grove Cottage and Mapes don't seem to be in the database)
Helen Faith Webb's page - lots of diagrams of individual ship actions in the series, as well as a map with locations of all subscribers to the Gunroom mailing list, affectionately known as Listswains. This is the modern equivalent of boatswain, often abbreviated as bosun.
