There are areas in the world with inaccurate or often reduced precision U.S. mapping - however that is not the case for the coastal U.S. Here, chart and GPS correspondence is very close on the coasts with a few known (reduced precision) areas. Unfortunately, the Bahamas is one of these.

I take your point to, "open the eyes and look", but you should know that anyone's ability to locate their position on a paper chart, using coastal piloting techniques will be significantly less accurate than WAAS GPS, except perhaps, again in reduced precision chart areas (non U.S.).
