Sailing

Weather can be manipulated to have some fun, too. Sailing manipulates the movement of wind and water to move around a lake or ocean. Sailors use the relative velocity of the wind to the boat’s movement, which is a combination of aerodynamic force and hydrodynamic force. The goal of sailing is to use every direction of the wind o be able to move as fast and directly as possible and, if the wind is constant, sailboats can sail 290 degrees of the compass. The directions relative to the wind, or the points of sail are:

• Close haul (sailing 22° to the wind)
  
• Close reach (Half way between close hauled and a beam reach)
  
• Beam reach (90° to the wind)
  
• Broad reach (22.5° away from directly downwind sailing)
  
• Running (Directly downwind)

You cannot sail directly into the wind, because no wind is hitting the sail, therefore no thrust. Therefore, fastest way to travel is being perpendicular with the wind, which provides the most thrust. You can change the direction and speed of a boat by harnessing the wind by arranging the boat and turning it until the wind hits the sails in a way you desire.
