1. Flow of air over sail produces pressure changes, producing lift & increases the speed of the wind over the upper surface

2. A combination of sideways force from the sail and opposite resistance from the water pushes the boat forward

3. A sailing boat does not blow over as the force of the wind is counterbalanced by weight & buoyancy
