I have Navionics Platinum on my plotters, iPhone and Macbook. Seems like there're updates almost daily. And updated charts are what you're paying for, right? Well, I also subscribe to the weekly USCG District 7 Local Notice to Mariners. I consult it anytime I'm leaving the dock and have for thirty years.

This week's LNM is week 47/2019. As I am headed down to Hilton Head for Thanksgiving, I checked the notices against my updated Navionics charts for a traditional trouble spot, the Dawho River. I was surprised to learn that a LNM notice from week 3/2017 about an added ATON (R114) is not charted. That notice has been published unchanged for more than 2-1/2 years! And, this isn't the first discrepancy of this type I've found before.

I dropped Navionics an email and got the typical corporate response. So, I thought I was paying Navionics to do the leg work. Anyone else have similar experiences?
