FYI-
I accidentally managed to become the first civilization to circumnavigate the globe when I had no access to any ships at any point in the game, and had no coastal cities.
What I did was to trade maps with other civs every so often relatively early on but when I traded them, I did not include my map in the trade. Apparently the game awards the circumnavigation bonus at the beginning of the next turn after the first player has a clear path across the entire width of the world map, NOT actually sailing around the world. Trading maps apparently is good enough to trigger the condition.
I'm not able to find anything about the circumnavigation movement bonus in the manual that comes with the game, so hopefully this isn't useless information.
It didn't help me directly in that game (landlocked OCC game) but I could see how it might be handy if for no other reason than to deny the bonus to your enemies even if you can't use it.
