T&T: Anchoring and anchor watch

[Mike Maurice]

I have been using the GPS anchor alarm for over 10 years. Since about 
the time that Garmin started putting the alarm in their GPS's.

I have not solved the problem of swinging, the GPS not being over the 
anchor itself and the other problems. I generally set an alarm circle 
big enough to keep the false alarms down to a minimum. I turn on "save 
track" and visually examine the track marks to identify if the boat is 
in fact dragging. The end result is a system that generates false 
alarms, but not frequently. This is not foolproof, but at least I can 
examine the track marks and convince myself that no significant dragging 
is going on.

This is not a solution, but it is a method. I have tried all the tricks 
that have been mentioned in this thread and have settled on the method 
mentioned here.

Regards,
Mike
