Windage and Wind Speed 
The "windage" of a ship is determined by her shape and surface area presented to the wind. The more the wind blows the greater effect it will have. Two general effects are simulated: 
  • The speed of the ship in the direction of the wind is increased or, conversely, the speed toward the wind is reduced. 
  • When the wind blows against the side of the ship, the bow tends to turn slowly down wind. Most ships and boats have less lateral resistance under water in the bow than in the stern such they when blown sideways, the bow and stern respond differently.
