Even the latest chartplotters cannot keep up with aids to navigation added to mark shoaling, and it can be confusing to approach a marker that often just does not make sense when looking at the chart. Thanks to Capt. Butler for bringing these uncharted markers to our attention!
New red nun 166 in Ashepoo River to mark shoal and the QR168 where you make the hard turn to port for the cutoff. Also noticed a new G175 in place of the range in Rock Creek.
