In this note below, the crew of “Restless” is referring to the two potential anchorage, north and south of Elliott Cut’s westerly entrance. The AICW travels though this man-made canal on its way from Ashley River (Charleston) to the Stono River. I have anchored in both these spots myself over the years, and have seen many others do so, BUT these are very unsheltered waters, and “Restless” is quite correct in relating that there is PLENTY of current.
You might consider the recommended waters (see below), off the Stono’s western banks, north of St. Johns Yacht Harbor (A SALTY SOUTHEAST CRUISERS’ NET SPONSOR) and the Highway 701 bridge. I’ve never tried dropping the hook here, but it sounds as if “Restless” found a good overnight haven.

I would not anchor in either of these two locations shown by the western entrance to Elliott Cut. The current really rips through here because the river narrows down as it swings past the shoal. A better location to anchor is to the south-west, along the western shoreline just north of the St. John’s Yacht Harbor marina. Be aware that there can be a 5-6 ft. tide here when picking your spot to drop the hook. The current in that location is somewhat less, but be prepared to swing through 180 as the tides change. You can dinghy to the marina for ice, etc. Call them on VHF 16, they will shift you to VHF 71. Inquire about facilities use if you are anchored out. See the listing for this marina it is accurate.
S/V Restless

I [anchored] several miles from the spot in question (up the Ashley River) and have been anchoring near the more Southern of the two spots shown for several years, but as close to the point as possible considering the water depth. This is one place we go just to get away but not go far.
I will agree on the lack of shelter but we only go in fair weather. We anchor overnight and although there can be a strong current, we have never slipped anchor.
Moving down towards St. Johns Harbor, there is a large shoal where local go to beach and play. Also, there have been some sunken boats in that area.
