The water turfs have been changed so I need to change this also =)
Ship will have 4 directions. Whenever your ship is on any water surface it will start sailing toward the direction of the wind. There will be 4 wind directions north, south, east, west. You can move against the wind but it will be slower. I suggest just flow on where the wind direction is and you should get to your destination faster. Sometimes the wind will not be present so your ship will just sail lol.
On the shore and dock the ship will not move.
On deep water you should be careful. If you are near the deep water there will be a special message that will appear or there will be blinking on the screen. It depends on you if you will go. If you have quality ship then just fight it. When you are not sure then just don't go to avoid dangers and be sunken pirate ship.
There should be an icon for the weather condition of the game like sunny, cloudy. It will look like a small orb and inside it is a thing that represents the weather. If the rain and thyphoons are present, the water will flow faster. And big waves will be seen and rain and storms.
