Sorry for the quality. Picture is a letter in Pacific Yachting and clearly demonstrates the need for continued use of proper paper charts.
No, it really doesn't do that. Paper charts have their errors too. What it clearly demonstrates is the need for more than one set of charts to serve as a check on each other.
It may or may not also call Navionics into question as one's first choice. We have electronic "paper charts." Only difference in them and paper is they're always up to date. Also there is a system that Transas has that will keep the dates of your paper charts and give you a list of all updates since their issue.
