Almost all GPSs have anchor watch alarms and radars have range alarms but
they all put out a whimpy little beep. Is there a device that monitors
the
NMEA data streams (from say a multiplexer) and make a noise that will get
your attention when it sees an alarm or MOB statement??

Mmmm, interesting option :-)
I know that the Seatalk-NMEA brigde from Raymarine has a dedicated alarm
output. But this one only works on Seatalk alarms.

A microcontroller-and-electronics hobbyist could make this for a few bucks
though...
