Where can I find a map?

[Linfried]

I am just starting out and want to know where to find a map I can use to travel the seas.

If you hit TAB while at sea you will see what that does.
You can find a good one in the guide section here.
You can find them as loot on dead captains. These show individual islands in detail as well.
There is a cheap one you can look at by using in your inventory but it's a basic world map and I am unsure where you actually get it. It was just in my inventory one day. It's the other one in the guide section here.
