A while back the CG questioned boaters in San Diego about the need to restore a sunk SD buoy that marked the approach to SD from the sea. The CG was under the impression that electronic charts and GPS were all the typical boater needed, and no actual physical buoy would be required.

They have since restored the buoy to it's proper location.

While GPS is quite handy and very nice to use, a local chart runs in the cost range of 25 bucks or so, were as a GPS with charts may easily run a couple hundred dollars...

I guess it all depends on what boaters to address as to what sort of charts they carry.

I recall once being off the coast in the La Jolla area... just north of San Diego, working my way south, and being approached by a power boater and asked "where is the channel entrance?"
