Please note that this grounding was near high tide in the center of the channel. We have reports of recent shoaling in various spots in the AICW between Charleston Harbor and McClellanville, particularly at Mile 431. Past advice has to been to stay in the center of the channel. Maybe this new spot will be an exception. See the link for more on this area.
We hit a shallow spot (less than 5 ft) north of Charleston just past Graham Creek between markers G64 and G61. It was close to high tide and we were aground right in the middle of the channel just opposite a small creek on the east side. I suggest staying to the green side of the channel to avoid this spot!
