    I do this at the moment with my iPad (thats left on the boat), and iPhone (thats in my pocket). With Apple’s Find My Phone. Its all free with the system I already have.

  2. Dean, you’re well set up to use the Boat Monitor app and service. For $5, it would give you a serious anchor watch, not just a look at where your boat is. I wrote about it here: http://goo.gl/n7RRj
    I’ve now tried the iOS version and it’s nice. It even has the pie slice exclusion zone that is favored by anchor watch afficionados: http://goo.gl/VAk4f

  3. Interesting: A UK company called AnchorWatch is offering a 12v load cell and LCD monitor designed to measure the strain you put on an anchor when setting it and then to alarm you if the working strain exceeds a tested max:

    I don’t see any facility for off boat monitoring but it seems like that could be easily added in a future version. The current model costs about $300. Thanks to reader Richarad Ross for the reference.

    Smartphone apps like AnchorAlert are good options, which I have on my Android, but they’re GPS dependant. In the Pacific NW those cruising into BC and SE Alaskan waters know that some anchoring locations have very steep mountains that can reduce and even obscure GPS signals. Although DeepBlue AnchorAlert is more expensive, it’s another good non-GPS sensor solution for anchoring.

    Ben,
    This is interesting but I am not sure I want to tie into cellular / internet. Most of the time I am looking for an anchor watch solution when I am at anchor and want to sleep.
    My 10 yr old Raymarine RL80 has a very function anchor alarm but that is up in the pilot house. It is interesting that the newer systems do not have this basic feature. I have Rosepoint which does not have an anchor watch…it can get me to the anchorage, but then I am on my own. I have NMEA2000 with GPS input into the backbone, but N2KWatch cannot do an anchor watch without upgrading to a many thousand dollar version. It also cannot send me messages to my iPad or telephone without this upgrade.
    I need to replace my two displays and chartplotter but until I find a solution that meets my needs, I will stick with the older technology.
    Garmin seems to be headed in the correct direction.

    isnt this Very simular to the boat sense device that hamilton marine was selling? if so the Cell coverage issue up here in maine is a very real downer to the use of this. The price is better though!

  7. Well, the GTU10 is a portable GPS tracker while Boatsense ( http://goo.gl/tuq3E ) is a fixed boat monitoring system, but they both do use GSM cellular. I think that at least AT&T service is a little better than it was around here, though still mostly Edge data rates. I’ve only had the GDL 40 fail to deliver weather once this summer, but then again its antenna is up on the flying bridge rail.

    Henry,
    The current crop of Garmin units have an “Anchor Drag” alarm built in. They allow you to set an alarm radius and if you exceed that distance….they will alarm. They also have the ability to trigger a remote alarm so you could mount an additional buzzer near the captains berth to increase the odds you will hear it.
    Sleep tight….

    The problem with the Garmin alarm is that you have to set it when you drop your anchor or the circle will not be valid since it is not centered on the anchor. The Android application asks the distance to the anchor and the direction. It draws a circle around the anchor. The person who wrote AnchorAlert obviously anchors a boat. It is hard to understand why Garmin can’t/won’t do this.

    Funny, that was also my comment about Furuno an hour ago. Why the big manufacturers can’t see this is beyond me.
