Wind shear is always present. Determining how much there is will improve sail trim and performance, and offer a clue about future wind shifts. Determining shear is best done by tacking upwind in full racing mode. Shear is half the sum of true wind angle on the
Learn more →Wind has a third dimension Wind shear and gradient are universally existing natural phenomena caused in part by the earth’s boundary layer. They are differences in wind speed and direction that change with altitude. We define wind shear as a change in wind direction with altitude, and
Learn more →True wind speed and direction are the drivers of your boat The wind you feel onboard a moving boat is a combination of true wind and boatspeed (the apparent wind). By solving the wind triangle, true wind speed and angle is obtained from the measured apparent wind,

Learn more →Sailing Instruments are more valuable than new sails Sailing instruments that provide true wind and current are an important advantage for racing; more valuable than new sails. Not having true wind and current means you race with your hands tied behind your back. For example; Detecting and
