I am not sure where “where ever” is, but some areas out of the 1st world are using surveys from 100-200 years ago to make those electronic charts. Recently the US Navy drove a minesweeper onto a reef for just this reason. Also note the vector chart plotters will lose major details when zoomed out, including entire islands. This resulted in a multiple fatality in California recently.

Many digital charts are based on soundings that may literally be hundreds of years old and would certainly predate GPS. I was in Panama this summer and my Navionics gold charts would have had me drive over a bunch of reefs if I had let them. (I used paper charts from the cruising guide which were spot on) I'm not sure what the chart accuracy is in that part of the world, but if there was any question of dodgy charts, the race committee ought to have given that area a wide berth. It would have been simple to set up a waypoint well offshore in deep water. Putting people at risk that way is irresponsible, imo.
