True wind vs apparent wind
WebMay 14, 2024 · Wind angle is the single most important factor in downwind sail design, but the terminology can be confusing. Many sailors think in terms of True Wind Speed (TWS) and True Wind Angle (TWA). True Wind combined with Boat Speed creates Apparent Wind, which is what really matters for downwind sail size and shape. WebWhat is Theoretical Wind?

If a boat sails absolutely perpendicular to true wind, so the sail is flat to the wind and being pushed from behind, then the boat can only go as fast as the wind—no faster. That’s not because there’s no apparent wind; it’s because the apparent wind can’t help the boat when it’s hitting flat against a ...
