VMG Mode
In VMG Mode the SC-1 shows your Velocity Made Good based on a wind direction you have defined.
The display is updated at 2Hz (twice a second). The SC-1 calculates your VMG upwind and downwind
using the method illustrated below:
Whether you are sailing upwind or downwind, the SC-1 breaks your boat's velocity into two
perpendicular components. One component is perpendicular to the wind direction. This component
is effectively wasted as it is not helping you make any progress upwind or downwind. The other
component is parallel to the wind direction. This is your VMG.
