Many of the paper charts in Florida are off, mostly because they’re out of date and/or plotted in pre-GPS days.
Boca Ciega Bay, where I keep my boat in St. Petersburg, Fl., bears no resemblance at all to the 1984 chart that is the latest available. There’s now an unmarked 20-foot-deep channel where there used to be shoals, for example, and most of the bay is a couple of feet deeper than charted. Many years ago, my older daughter and I did a science project using a GPS to check paper charts for Biscayne Bay and the Upper Keys. Many well-traveled routes were dozens or hundreds of feet off, and anyone using the charts with an autopilot would be aground.
