It's easy to get confused. Global Navigator does NOT include ENC
support but the Marine
enc version 4 does plus it does all that Global Navigator does.
I just checked to day and the viewer is no longer free but $19. I bought it a long time ago when it was free with $9 shipping
. It gives you an idea of how Fuhawi looks but you can't do much with it.
I own the Marine ENC version and like it quite a bit. The cheaper Global Navigator will handle raster charts BUT the free NOAA raster charts will not auto switch between themselves as you can with the Maptech
charts you still have to pay for.
The new 3D feature does not include bathymertric displays. It will display 3 D on the land but not sub surface on the water
. It also takes a fast computer to run 3D. I've not found it usefull on the water
but it is fun at home.
