I have ended up using a number of software
products and map publishers. I didn't plan it that way it just happened.
My primary ECS is a Raymarine
C120 plotter with Navionics
charts. I use this system continuously while underway.
I also run a PC-based navigation
system as backup and an alternative view to the Raymarine
plotter. I started this PC sytem using Fugawi
with NOAA ENC
charts and raster charts from Maptech
and SoftCharts. I liked to have the alternative view of the raster chart images
to compare to the vector charts on the Raymarine plotter, especially when making a landfall or entering a harbor.
Since then I've added an AIS
receiver to my electronics
and have started using SOB software
from DigiBOAT as I like it's robust AIS presentation. Unfortunately SOB only works with C-Map
charts. So now I have another set of vector charts to purchase
and maintain. I expect I will continue to use Fugawi
and raster charts as my backup to the Raymarine and use SOB primarily when navigating busy commercial
channels (like my recent transit of the straits of Gibraltar).
So I currenlty use three plotting packages (Raymarine, SOB, and Fugawi) and three chart formats (Navionics, C-Map
, and BSB/Maptech/SoftCharts).
I also have the SeaClear II (freeware) and Offshore
Navigator (free when I purchased several Maptech
charts packages of the Med) programs installed, but do not use them actively for navigation.
