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

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

The importance of true wind in winning The importance of true wind cannot be understated. True Wind is the sailboat’s fuel supply. Of all the functions that an instrument system produces, true wind is the most important for performance, tactics and strategy during racing. Wind direction is

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,

SailPlan crossover chart is a live sail display that, in conjunction with instrument data and the current course, displays sail crossover information for the current and next leg. When a polar is included, apparent wind speed and angle, and target angles are also shown. Current wind conditions (the

Lateral separation pumping leverages wind shifts into big gains when sailing When sailing lateral separation is crucial. Being “On the wrong side of the shift” means that if you are to the right of your competition and the wind shifts left (or vice-versa), you lose distance to

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
