As Jon pointed out earlier, first of all we should see OD and WD as separate plugins.
In OD, just a graphical, visual presentation may be added to areas, to indicate whether these are intended to avoid or to stay within (or whatever other meaning you want to give to those graphical indications).
In WD you can select whether (certain types of) alarms should react only for areas that are (in OD) flagged as to avoid, or to stay within, or for all areas. On top of that, you can indicate in WD whether this should be done only for areas labeled in OD as active, or inactive, or both.
The WD Boundary Alarm has 4 different types:
1. alarm when approaching an area from outside (based on distance)
2. alarm when approaching an area from outside (based on time)
3. alarm to indicate whether you are inside or outside an area (another type of anchor
4. alarm to indicate whether AIS
objects are present in an area.
For each of these 4 types of WD alarms, in OD the area can be flagged to avoid, to stay within or to be a general area without additional graphical indication, and to be active or inactive. Not in all possible cases these parameters will effect WD.
Only for the first 2 types of WD alarms mentioned above, in WD the alarm can be flagged to react only for areas that are (in OD) labeled as to avoid, or to stay within, or for all areas. And again, on top of that, you can indicate in WD whether this should be done only for areas labeled in OD as active, or inactive, or both.
Beside the 4 types of Boundary Alarms mentioned above, WD has the following alarm functionality:
1. alarm when approaching coastlines (Landfall Alarm)
2. alarm when NMEA-data stream stops
3. deadman alarm
4. alarm related to distance to reference position (anchor alarm)
5. alarm when course over ground deviates more than set;
6. alarms when speed deviates more then set (two types: overspeed for more than set maximum, and underspeed for less than set minimum).
In total 11 different types of alarms.
