Wind energy propels a sailboat by transferring force from the wind to the sail, which then pushes against the air, creating movement. When sailing parallel to the wind, the wind exerts pressure on the sail, causing the boat to move in the wind's direction. The design of the sail creates irregular air pockets that enhance propulsion. Without sails, a boat would simply drift with the water, but the sails trap air and generate resistance, allowing the wind to push the boat forward. It is important to note that sailing directly against the wind is not physically feasible.
