21- IMPROVE YOUR TACKING PATTERN

The VMG polar charts in raceQs are a great tool to evaluate how quickly you complete and recover from your tacks. The VMG overlay is visible in “match mode”, and tracks your progress through the tack on a polar chart with the true wind angle as the vertical axis, shows your course as the angle of the vector, and your speed as the length of the vector. Each second, a colored dot indicating your VMG appears on the chart, showing your VMG for that last two minutes in a color-coded cloud.
