I haven't had many problems with an anchor dragging, but it seems to me that the only times it has happened is when the wind either increases or changes direction. Those are probably about the only times it's going to happen.
What all the marine electronics provide is drag detection alarm based on GPS. Seems like the horse has already left the barn at that point. I'd love it if someone provided a drag detection alarm that was based on a logical combination of wind speed and direction. This could probably be a pretty simple NMEA based embedded microcontroller that picked up wind speed and magnetic direction off the network. If I go to sleep in a 5 knot wind I would really like to be woken up if the wind hits 20 knots at 3:00 AM. It would be a lot easier situation to deal with than waking up halfway to the beach, already tangled in a couple of neighbors rode lines Is it just me, or is there a market for such a device?
