Designing Tracks
From VRTool wiki
Before designing tracks or performing route optimization, make sure you have data files loaded (winds and polars) as described. Also check if the track designer settings are correctly set.
Click the track tool button. Click the first point of the track you are planning. Always start a new track by clicking your current boat position.
As move the mouse, track data can be viewed in the floating cursor and in the boat attitude indicator. Left click the mouse to add a point to the track. Use backspace key to delete (correct) the last point. As you draw the track, point times will be calculated based on polar charts and wind data. Appropriate wind forecasts are selected as you go.
