From earlier reports and as Captain Bell confirms, the water gets thin between AICW markers #111 and #119, north of the Waterway’s entrance into Charleston Harbor. While not yet designated an SSECN Problem Stretch, we have established a Navigation Alert for these waters and caution should be exercised through the AICW channel past the Isle of Palms.
Three days ago we had to wait for one hour past low water, which was “0″ tide, to pass between 117A and 119. Our sailboat has a five foot draft. We made two slow attempts to pass but ran aground mid channel and west or land side of mid channel. NOTE: while we waited for an hour past low tide we made an attempt to bypass the low spot by going around the Atlantic side loop. The chart shows deep water, which there is until you are 100 yards from 119, then there is a shoal that is less than four feet. So back to 117A you go.
