The concept that explains how sails generate power is which term?

• A. Push-Pull Principle
• B. Pushpit
• C. Rake
• D. Range

Answer: (A)

Sails generate power through aerodynamic lift. The sail acts like a wing, and as wind flows across its curved surface, air speeds up on one side and pressure differences develop. Because the sail is set at an angle to the wind, that lift force isn’t straight sideways; it has a forward component that pushes the boat ahead. The other terms don’t describe how sails create propulsion—one isn’t a recognized sailing concept, one is a hardware piece at the bow, one refers to tilt, and one is not related to sail power.
