Depth Alarm would be nice

[dominig]

Adding an extra alarm based on Depth warning would be great (getting bigger or lower than xx meters. Leaving in a strong tidal area (Brittany), it's a common need for any one dealing with tides.

I agree, but I do not have a depth sounder.

I just built an anemometer from an arduino though, so will be working on wind alarms.

Sean,

please find joined to this mail a NMEA log that can be replayed and includes depth data which varies (I sailed over shalow water to avoid a regata :-)

rooiedirk suggested an alarm if the boat crosses the vector chart "Shallow Depth" or "Safety Depth" optionally.

this is unfortunately really hard to implement otherwise it would have been years ago for watchdog and also weather routing

Why so hard for vector? Can't a query be made for how close to the shallow depth line? It similar to the "Detect Land" checkbox in weather_routing.

detect land uses gshhs

Isn't there an algorithm which draws/establishes the "shallow line" which depth can be compared against?

Sean, see this!! He has a nmea0183 depth tranducer for you! Contact him Post #485 cmckinnon

Sean, did you get in contact with cmckinnon about the depth sounder?

[seandepagnier]

The depth alarm is added.
