1927 datum?
Good grief. Cheers MC Scott Vernon wrote: Well, right under the sea serpent and above the mermaid it says '' 1927 DATUM , Soundings in Feet at MLW'' Low Low Water Low Tide????? SV "Jeff Morris" jeffmo@NoSpam-sv-lokiDOTcom wrote in message ... 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 "Scott Vernon" wrote in message ... Found the 'old' chart. It reads '' controlling depths in feet at Mean Low Water (MLW)''. AND; depths reffered to soundings (MLW)''. Scotty "Scott Vernon" wrote in message ... Are you sure? Don't keep charts at the house, thus the ''I believe'' . SV "The_navigator©" wrote in message ... No they are not. Read the chart legend Cheers MC Scott Vernon wrote: I believe that charted depths are given at MLW and it's up to the sailor to know the tide table and apply it. |
