Would someone please refresh my memory about the sounding contour
lines on charts?

They are fathom lines, the first 6 feet MLW, the next 12, etc. Is
that right?

===================

Depends on the chart.


I cast around, and found sources that seemed to indicate fathom
isobaths, fathom n feet for shallow isobaths, others marked in
meters, or feet.

I guess, user beware....

For any chart, you should read the legend block. It has indispensable
info, including the units of the soundings and the chart datum.

And, Chart #1 is also necesary for understanding the conventions in
use.
