Speed Alarm Speed over ground > X and < X
Deadman Alarm No activity for X min
Anchor Watch Radius, boat location
Off Course by > X degrees, with course of X degees.
Alarm action sound, command, message box, repeat
Some updated changes to Feature Requests.
Nmea Data Alarm -
No GPS for > seconds (works)
No AIS for > seconds (does not seem to receive data always N/A)
AIS CPA Distance to Collision Alarm < (nm or miles) [may be redundant]
AIS TCPA Time to Collision Alarm < (minutes) [may be redundant]
-Are AIS alarms in Watchman redundant?
Off Course Alarm -
Off Course by greater than > (1-180 degrees) (works) :
- Port and Starboard off course settings- eg towards destination, danger.
With Boat Course = (degrees)
- Permit entry of a value from 0 to 360 (0-10 now)
- Or Press "Current Course" button & completes with GPS COG.
Current Course Button does not populate this value from COG.
Sensor Choice - GPS-COG or Compass.
(add) -Cross track Alarm - Shows perpendicular distance left or right of course. When sailing with a wind vane, it would be nice to have an alarm go off if you started to wander off course due to a wind change. An XTE alarm would alert you so you could make changes to sails and wind vane direction to get back on course. It might also be the first warning you get if your autopilot quits...
Waypoint arrival alarm
(add) - Similar to above but will alert you when you need to make a course change. Not as important when using an autopilot, but very important if using something like a wind vane.
Depth Alarm - (add)
Good for both while at anchor and to exploring uncharted inlets.
Useful for detecting anchor drag or if you missed a shallow spot when checking out an anchorage.
Shallow -Depth less than < (feet or meters)
Deep - Depth greater than > (feet or meters)
Follow Contour using above, both enabled.
(range? some sensors only go to 200', check for Null?)(range? some sensors only go to 200')
Bilge Alarm - (add)
Low water level alarm
-Average Frequency last day
-Average duration last day
-Average Frequency last 30 days
-Average duration last 30 days.
High water level alarm
-Connect to a sonar dive dive alarm
Wind Speed-Direction alarms
High Wind speed - knots, mps, kps
Low Wind Speed - knots, mps, kps
Wind Direction - degrees Set button from instrument
Port Wind Direction - change
Star'd Wind Direction - change
Watch Alarms (add) -
A timer (length determined by user) that is reset whenever you interact with the program. If you should doze off while on watch, it will wake you up after a set amount of time. Press a button or click to reset timer at any time. It would be nice to have a warning appear before the alarm sounds, i.e. a dialog box would appear and flash for 30 seconds (user settable) or so before the beeping started to keep from waking everyone up if you forget to click...
--- Watchman has this without some of the detail.
Alarm clock (add)
- Alarms set to specific times to signal watch changes or other events
Boundary Lines / alarms
- In Nobeltec
I could mark boundary areas that would set an alarm off if crossed. I used them to mark shorelines / obstructions that might be encountered. Very useful when single
handing at night when you might dose off... if lines are set at reasonable distance from dangers, gives you notice if you wander too close.
Perhaps this is where to implement this feature, if not perhaps somewhere else.
Weather alarms -
many boats have weather stations connected with NMEA output. Wind speed might be nice as a reminder to reef the sails... though I admit, this is usually obvious unless you're sleeping and have less experienced crew on watch... Another would be rapid change in barometric pressure.
Separate sound files for each alarm.
Visual alarm popup has the alarm and value.
Dismiss button for all alarms.
Turn off all alarms button?
A note of encouragement about the future (more complexity):
"There are plenty of other alarms that might be nice as well. With all the NMEA data that can be available on a boat these days alarms for engine
monitoring (oil pressure, temperature), low voltage, high voltage, high water... I don't have any of these data sources on my boat yet, but maybe someday..."
...have tested updated version of "New Watchman Plugin" and "OFF Course Alarm" works fine. But still "Current Course" button doesn't populate COG in "With Course Of".
