The reason for this I like to charter overseas and tend to have data roaming off so that I do not run up lots of extra phone charges, and would want to be sure that google map was not using up lots of dosh.Ĭan you have a numerical value on the range in Meters and the option to set the range in meters. We thus have virtually no experience of phone based anchor alarms.Just got the Anchor Drag app and have been messing arround with it in the garden… looks good thanks. We also have a berth mounted compass and when a front is expected we can see the orientation of the yacht, has or has not, changed, is changing, and that the front is arriving.

It might be complacency but we are sufficiently confident with out anchors and use of same that we only set an alarm, with the chart plotter whose aerial is 'outside', in exceptional circumstances (and it has a piezo electric alarm added), when we expect the arrival of a major front or we are anchored somewhere with strong tide reversals (not common where we cruise).

However we have not dragged either - so maybe my caution is misplaced. I treat the comments with some caution as their does appear to reluctance to admit that ones spanking new (and expensive) modern anchor is not all it is cracked up to be.

It may turn out to be 'operator' error, an error in the App or something specific to iPhone It may also be something to check anyway.Ī few years ago I solicited comments on the frequency with which modern anchor dragged and apart from catching supermarket trolleys and the like no-one admitted that their modern anchor had dragged.
