New Continent should be farther

The new continent should be not reachable by coastal water. It would only be reachable after travelling ocean for at least 2 turns in deep water (oceanic hexagone), forcing the necessity to research the Three-Masted Ship technology from the Early Modern Era.

Actually, the new continent is discoverd too early, and if you begin the game too far away from the new continent, you will be the last one to settle a new colony on it.

While, even if you are starting the game far away from the new continent, you can have the time to localize the aera where the new continent should be by discovering the map with your ships : if you loose ships because you spend too many turns in deep water trough one direction in the hope to reach coastal waters, you can conclude that the new continent is beyond.
