The VMG polar charts in raceQs are a great tool to evaluate how quickly you complete your tacks and recover your speed.  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. 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.
