Captain Butler offers good advice for the Waterway channel near the southern tip of the “Cumberland Dividings,” just north of where the AICW intersects the southerly reaches of the Brickhill River. This “AICW Problem Stretch” has multiple problems. First, some charts and chartplotters show the magenta fairway line running on the western side of the red markers in this area. Those who blindly follow this erroneous magenta line will run aground every time. Also, and perhaps even worse, the Waterway is shoaling badly along its western flank, north of marker #63.
Channel is well marked, looks like new markers were installed. Definitely follow the markers and not the magenta line on the charts.
