The C-Map card I have currently NA-C324.05 which covers Sandy Hook to Wilmington DE. The problem is it ends right around Keansburg NJ and anything west of that leaves me in a sea of white on my GPS. Seeing as I am docked in Keyport and fish all the way up to the railroad bridges in Perth Amboy at times, this is a small problem. I am looking for a C-Map NT+ card that covers all of Raritan bay basically from the Railroad Bridge out to about 10 miles offshore and south to at least the Shrewsbury Rocks. is there such a card out there? I'm looking everywhere and honestly I don't think there's anything more confising on the internet than trying to decipher C-map locational maps.
