There are three very shallow areas coming south. One just inside of the Wrightsville Bridge. The opening between shore and green can is very tight. All shallow areas not marked. I am 4'7" and had some hard times I do not want to repeat.
We transitted this stretch twice in the last 60 days with 4' draft. In center channel we had no issues. The "S" turn north of there was not a problem either; we followed the marks, gave them some room and went right through. Sneads Ferry area had a few skinny spots but nothing shocking. Swansboro was a breeze.
A local described the Ben Sawyer/high rise bridge area as the endzones of a football field with bad shoaling between the 40 yard lines that at low tide got as shallow as 2 1/2 feet. When we came through several weeks ago northbound there were two barges of dredge pipes about McCellansville headed south so maybe this is being addressed.
