VMG
Velocity Made Good (VMG) is the component of Boat Speed in the direction of the True Wind.
VMG is used for monitoring performance of the yacht on upwind or downwind legs as the
data considers both Boat Speed and True Wind Angle therefore indicating whether sailing
slower, but closer to the wind, is better than sailing faster, but at a wider TWA.
