The information below details the warnings that can be displayed when using automatic route generation, a
description of what the warning means and actions to be taken to correct the issue.
Example warning message Description Resolution
Route generation completed successfully The Route maybe followed AFTER it
has been reviewed to ensure that the
generated route is safe for your vessel
to follow.
Route generation completed successfully,
however the route passes close to areas
where extra caution is advised (e.g. a
charted buoy).
The caution areas will be between
waypoints that have been assigned
caution symbol.
The route must be reviewed as follows:
• Identify any waypoints using the
caution symbol (these will be in sets of
2), check between the caution symbols
to identify the reason for the caution.
• If possible move the waypoint(s) to
avoid the hazard.
• Review all route legs and their
waypoints to ensure appropriate
before following the route.
The start and or end point of the route
does not meet the minimum safe values
specied in the Boat Details settings.
The start and end waypoints will be
created and joined with a straight
route leg, however there will be no
automatically generated waypoints and
the waypoint symbols will be changed to
caution symbols.
Perform the following checks:
• Check that the values specied in the
Boat Details settings are correct.
• Using the context menu check the
Chart Objects menu at the exact
location of the start and or end points
to establish if the Depth range meets
your Minimum Safe Depth.
Note:
– If no minimum value for depth
is available at the desired
location, a minimum depth of 0
feet is assumed.
– Automatic route generation
adds its own safety margin of
0.8 m or 20% of the specied
Minimum Safe settings. which
ever is greater.
• Check for any other hazards that
would prevent route generation.
There is insufcient data available on the
cartography to generate the route,
The start and end waypoints will be
created, however there will be no
automatically generated waypoints and
the waypoint symbols will be changed to
caution symbols.
• Insert compatible cartography
• Update existing cartography
Note: There may be certain areas
where sufcient details are not
yet available even on the latest
cartography.
