True wind vs apparent wind
WebTwo work as one. The wind that blows on your face when you are in motion and to which you trim your sails is apparent wind. It is a combination of true-wind velocity and direction and the boat's speed and course. When you are sailing close-hauled, the true wind is most likely about 45 degrees off your windward bow. WebRaymarine products require the following data items to calculate True Wind data: • Apparent Wind (Wind instrument) • Heading (Autopilot or Heading sensor) • Speed …

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.

WebSailing close to the wind uses the shape of the sails to generate lift. To flow around the sails, the wind has to deviate in direction, as shown by the arrows for initial velocity vi and final velocity vf, which are given with respect to the boat.
