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

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....
