Definitions for "Velocity Made Good"
See VMG.
actual boat speed in relation to a specific direction
Digital speed reading, similar to Speed Over Ground (SOG), that compensates for progress being made toward a waypoint. For example, when traveling directly on course toward a waypoint, the SOG and VMG readings may match. However, when traveling off course, the VMG reading will typically be slower than the SOG. VMG is a true indication of the speed being made to the selected waypoint.
