and sometimes there are plain errors. For example the local Long Beach (CA)
chart's insert for the downtown marina had the wrong longitude number inserted
at one point. Off by 0.1 degree, quite a distance. I reported it some years
ago, so probably fixed by now.

I was
motoring up a harbor looking at a nice Raymarine system
showing the boat going through a sea wall 200 feet west of
our actual position.
Yesterday while motoring in the ICW
channel in Santa Rosa Sound near Navarre, FL, the
chartplotter boat took out several of the buoys on the right
side of the channel.

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.

I used C-Map on Standard Horizon

accurate to the foot.

Just because charts are digital
doesn't mean they are accurate.
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.
Cheers

was a classic case of being too far zoomed out on the chart
