Displaying and interpreting laylines

Once laylines are enabled and correctly configured in the Laylines tab in the Chart app Settings, they
will start rendering on the Chart display as your vessel is underway.
Laylines are displayed as a parallelogram under the following conditions:
• The vessel is under active navigation towards a Waypoint or Goto.
• A tack is required to meet an active Waypoint or Goto.
• The direct distance to the destination point is less than 150 nm from your vessel.
When the destination point is upwind the laylines will be displayed in a parallelogram formation, with
green and red laylines showing the port and starboard tacks, as shown below:
1. Destination
2. Starboard destination layline
3. Port vessel layline
