Retriever, like many other cruisers, advises passage within 2 hours of high tide, preferably a rising tide, while cruising through this “AICW Problem Stretch.” The crew of “Retriever” also cautions against staying glued to the magenta line of your chartplotter. Look at the markers!

Passed through the Cumberland Dividings about 2 hours before MHW. Look at the markers ‘“ not your chartplotter, it’ll take you into the marshes and shoals to the east. The only `issue’ was at the sharp right turn at the bottom of the Dividings (all the reds are clustered together). Retriever saw 6’ ‘“ so would not of wanted to traverse that stretch at low tide considering those South GA tidal variations’¦

And, from Captain Pascal regarding this same AICW Problem Stretch:

I’ve always timed passage just past high tide since i usually stop before Little Mud River and timed that entire section around the tides (70MY, 6+ draft)
So far I’ve always found only 7 to 8′ MLW thru Cumberland Dividing but this year (Oct 30th) I went much further to the green side than before and never saw less than 12′ or so.
The key after G59A, southbound, is to stay on the green side, and aim for that ghost round island seen on the chart across from R60. at that spot, you will have 13′ MLW
