🔍 Key Concepts

• Fore-and-aft sail shape when trimmed correctly • Difference between luff (leading edge) and leech (trailing edge) of a sail • How an airfoil (like a wing) is shaped to generate lift

💭 Think About

• Think about which edge of the sail first meets the wind and how that affects where the greatest curvature (draft) should be. • Consider how a wing of an airplane is shaped from front to back—does it start flat and curve later, or is the curve more pronounced toward the front? • Ask yourself which cross-section would help the sail start smooth airflow on one side and maintain attached flow over the rest of the sail.

✅ Before You Answer

• Make sure you know which side of the sail is the luff and which is the leech. • Visualize or sketch the cross-section of a well-trimmed mainsail from mast (front) to trailing edge and mark where the deepest part of the curve (maximum draft) usually is. • Eliminate any answer choices that describe a shape unlikely to produce good lift, such as perfectly straight or evenly curved with no defined draft position.
