I have noticed that you can make a pretty good amount of gold by selling map every turn.
How to proceed
sell map before moving your galleys
Sell map to the AI having the less gold first, when an AI is offering his map for yours, sell it back to every one.
Then move your first galley and sell map to everyone again, move your second galley and sell again.
Note: you also can sell map after moving your galley one square as far as you inlight some black, but I think this is cheating.
