Diana and I crossed the Albemarle Sound southbound last week and re-surveyed the known Alligator River Entrance ICW trouble spot ... with its westward shoal and mis-charted Magenta Line. Our depth-annotated track and report are here: https://www.facebook.com/notes/on-the-water-chartguides/alligator-river-entrance-depth-annotated-track/432212580161657 As you can see from the screenshot, the depths are fine if you follow the navaids, NOT necessarily the Magenta Line. Southbound, you would honor R6 and the G7-R8 pair, then (importantly) depart the charted Magenta Line, honoring floating navaid Red 8A, to stay off encroaching Long Shoal Point, finally re-joing the ICW and the charted Magenta Line at G9. I'll re-survey the other known ICW trouble spots as we continue southbound and share these as soon as possible. Mark & Diana Doyle m/v Semi-Local
