Semi-moderate CivIII Vanilla trick (by request): Note: This is to take advantage of being able to see an extra water tile out when fortifying naval units. 1. Best way to make this work is to get the Great Lighthouse so that your galleys can travel sea tiles without sinking. This will give you the best benifits of the trick. However, if that is unattainable, you will have to wait for caravels. 2. Build a few boats and load them up with settlers and defense units 3. Sail out to the furthest sea tiles you can in a direction where it makes sense for other continents to be. If all that you meet is ocean, then... 4. Fortify. On your next turn, the distance your boat will "see" out into the ocean expands another square. 5. Hopefully, three tiles out you should see a sea tile. Sail to it! If you get to a dead end and see nothing, move on and try again. Sometimes you can find several little single-tile spots of sea that allow you to jump some distance into the ocean and on to other continents. The earlier in the game that you can make this work, the better. You will have more time to colonize the other continent and meet other Civs to use as trading leverage against the Civs you have already met. Also: be stingy with your maps after this point. The AI can (I believe) use the route you did once it knows it exists, and the advantage will be lost quickly. This trick works pretty well on continents and archipelago... pangea, not so much.
