9.5.6 Geometry check of route
When you add a new waypoint, modify a waypoint or change other waypoint data, the
message "Impossible turn at WPT" may appear in red and the following items may
also appear in red.
• Turn radius or planned speed for the respective waypoint
• Latitude/longitude for the next waypoint
This means that the geometry of route makes it impossible for the ship to sail along a
certain leg. Typically it is enough if you do the following, on the [Waypoints] page.
• Decrease the radius of turn of the waypoint or one of its neighbors.
• Increase the radius of turn of the waypoint or one of its neighbors.
• Change lat/lon position of the waypoint or one of its neighbors.
Note: If the above-mentioned remedies do not remove the "Impossible turn at WPT"
indication, try changing the planned speed.
