Are you the same age as all your charts?

How old is that chart? All of my US charts from the recent past use


MLLW

as the datum for


soundings. I even checked in my Chesapeake ChartKit to see if they

were

different.


OK - Here's a quiz: What's the meaning of LLWLT?

BTW, I thought of commenting on the "8 feet above MLW" also - around


here

we have 10 foot


tides and flooding is measured above MHW

Found the 'old' chart. It reads '' controlling depths in feet at Mean

Low


Water (MLW)''. AND; depths reffered to soundings (MLW)''.

Are you sure?
Don't keep charts at the house, thus the ''I believe'' .

No they are not. Read the chart legend
