Auto geofence not activated when boat is at rode

Hi guys,

i have an FMB204 on my boat and i need to ask about auto geofence feature.

When i dock my boat on the port and turn off the engine, auto geofence is activated perfectly.

But when i anchor at rode and turn off the engine, auto geofence is not activated. I guess this is because when the boat is at rode, it is constantly moving at a radius around the rode according to wind direction.

My problem is that if the boat is stollen from the port, insurance do cover the lose but when is stolen from the rode it does not. So it is really important to be notified when the boat is out of the auto geofence.

is there any work around that we can do in order to activate the feature despite the fact that boat is moving?

thanks!
