🔍 Key Concepts

• Airfoil shape of a sail (like an airplane wing) • Difference between the edges of the sail and the main curved area • How lift is generated by airflow over a curved surface

💭 Think About

• Think about which part of the sail’s surface actually creates most of the sideways lift that drives the boat forward, not just where the sail begins or ends. • Compare the narrow edges of the sail (top, front, back) to the broad, curved body of the sail. Which one has enough area and shape to act like a wing? • Visualize wind flowing along the sail: over which part does the air speed up and change pressure to generate lift?

✅ Before You Answer

• Be clear on what lift means in sailing (sideways force turned into forward motion by the keel or centerboard). • Identify which choice refers to the main body/shape of the sail versus just a line or edge. • Confirm which part of a wing or sail is actually called a foil in aerodynamics and sailing terminology.
