…interestingly funny how the public tries to figure out how “Sailing” works!

  • “When properly trimmed (adjusted or positioned), the sail’s leading edge—the luff—points into the wind, creating higher pressure on the windward side (the side facing the wind) and lower pressure on the leeward side (the side away from the wind).”
  • “The sail “lifts,” or moves, toward the lower-pressure side causing the boat to move.  This happens because the sail isn’t a flat sheet of cloth, it’s curved, like a wing and the air traveling over the topside of the curved portion travels faster than that traveling on the underside.  (The curvature, or “draft,” is built-in by the sailmaker, through careful cutting and sewing of the narrow panels that make up the sail.)”

Well, seemingly intelligent, normal people don´t really know how sailing works. It´s not their fault. I mean, being put on the spot while a camera is on you is enough to make anyone nervous. But how is the pressure distributed, how the sails act like wings and how motion can build on itself is cool to understand.   Check Out how everyday “land lubbers” try to explain/figure out how the physics of sail lift works!!!!
