I don't have an alarm, but have had good results using my Garmin 640 GPS plotter when anchoring. I simply make a waypoint after the boat settles down. The 640 can be brought into the cabin, making it easy to check the boat's location and distance to waypoint after dinner or before bed to see if we've moved.

We're dragging! Thanks, Marek. I'm pretty busy during anchoring, since I'm often by myself. I usually just hit the MOB key when the anchor gets dropped, and after I am sure I am firmly set, I make a waypoint where the MOB position is and delete the MOB. I then simply "navigate to waypoint" which gives me a running graphical and numerical account of the distance from that waypoint. The boat slowly paints a smile on the chart as it swings back and forth. I can tell at a glance if the smile starts getting fat it means the boat is getting further from the mark. It also shows me if the boat has swung around to a new direction. No alarm, though. Seems to me it shouldn't be that hard to add an alarm feature tied to the waypoint that would mark a circle on the chart that could be made any size you wish. THAT is what I feel would be a very effective selling feature. Looks like I may be able to find an app for my android smartphone that will do this. I'd really prefer to have it in my dedicated chartplotter which doesn't get moved around on board, or carried to shore.

I don’t know of any way to move the centre of that circle (to where you want it to be). The only option I can imagine at this moment is to move the boat to the anchor and set the alarm there. Of course, it makes little sense. However, if you are prepared for that operation ahead of the time, you can set the alarm, when you are dropping the anchor. It should be a simple operation of pressing a key or two. Even if the boat is moving slowly, a few metres this or that way should not matter (unless your anchorage is that tight).
