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.
