There's 3 handheld GPSs, not counting what any guests bring, and two
mounted 12V GPSs on Lionheart. There's 4 chart plotters if you count
the Yeoman marking the paper chart from them. I can flip some little
toggle switches in the NMEA network and force GPS data to power the
network if any component, like the multiplexer, should fail. I'd say
we have a fair number of backup systems in case anything short of EMP
from a nuclear strike happens, in which case navigation won't be much
of an issue....



Crap....that isn't the correct number. I forgot to count the GPS receiver
in the 406 Mhz EPIRB in the ditch bag....
