This AICW Problem Stretch has been shoaling badly along its southern and southeastern flank between the Ben Sawyer and Isle of Palms Bridges.
On Tuesday, 4/28/2015, between 07h20 and 07h40 EDST, Sanctuary and crew transited Mt. Pleasant, SC, northbound, between the Ben Sawyer Bridge and Isle of Palms, at mid-tide (falling). Here is our observation report:
1. Shallowest water is north of G”119″ and nearby but south of Green floater G”117A.”
2. Exact path through the area matters; favor red for best water depths through this entire stretch. Proceed carefully in the vicinity of G”117A” at Swinton Creek.
* Almanac numbers based on Garmin chart plotter matched to Coastal Explorer’s tide table.

And this from AGLCA’s Forum:
Just north of Charleston is the swing bridge at the entrance to the ICW heading north. Between markers 119 to the next bridge (and mostly around marker 117) it is very shallow. After getting a positive trip report from
Seahorse on a successful trip, we went today. Only difference was an hour difference of tide. We watched a sailboat and a tow get stuck at marker 117. While TowBoatUS says to keep to the red side (port), the key is to go at least 2 hours AFTER low tide. The thicker water (note not a channel) is to the red side, but don’t stray too far. Note that there are shoals at the ocean inlets, so at those points the green side does get thin.
