Cannot always trust the charts

It seems that the San Benido islands are not where our NEW Garmin charts seem to think they are. Luckily we approached during the daylight.  Contrary to what the chartplotter shows, we actually went BETWEEN the centre island and the eastern one.


Then we found a nice safe place to anchor at a depth of 11.7m, not an altitude of 11.7!


We actually used our Navionics charts on our tablet, as they matched what we were seeing.
