We have been keeping an eye on Watts Cut for a couple of years. There seems to be a shoal building. Half way between G137 and G 135 we saw depths which would work out to 6.3 feet MLLW. There will be less water if you stray from center. If your boat draws over 5.5 feet it would be wise to transit Watts Cut on a rising tide.

Ashepoo Coosaw Cutoff between R 180 to R184 is shallow and narrow. Our track through here was along the visual center of the cut. On our track between R184 and G 181 the shallowest we noticed would be 6.1 feet MLLW.
This is significantly better than the 4.5 feet saw heading south, which tells us that that the track you take may yield quite different depths. Recommend that you have some tidal help and transit on a rising tide. R172 to R 168 we stayed in visual center NOT chart center. There is over 10 feet MLLW.

Buttermilk Sound R208 There is a distinct shoal building into the ICW. It is located about 400 feet SE of R208. At 31 8.744 N and 081 20.984W. It shows clearly on the Navionics Sonar Charts. If you are using NOAA charts or other cartography, you might just put a warning waypoint on your charts. Being that it is on the red side of the channel this is more of a concern headed south when you naturally stay closer to the red side of the ICW.

This has been a shoal area for several years. But there is 9 feet of tide here so with a little planning it is easy to transit. Our observations, after a number of transits over the past few years, is that if a tug and barge goes through at near low tide, the channel is deeper. This was the case in the spring of 2016, but it filled in again. In November of 2017 the best water we could find was only about 3.5 feet. A barge went through in mid-February 2018 and our passage on March 19, 2018 showed ... Read More
Little Mud River has some shallow spots in the ICW channel. Our track was established by the suggested deepest water shown on the Navionics Sonar Charts. We steered the boat according to the deepest water seen on the Navionics chart. Our course slalomed back and forth as we followed the suggested deeper water. In the end, we found nothing less than 5’3” along our track. A track right down the center or 30 feet either side of our track might have seen different and shallower water depth. My best guess is that a track straight down the middle would see ... Read More
The very name of this short ¾ mile stretch of the ICW strikes fear into the hearts of many cruisers. It needn’t. While at 3’6” it is the shallowest section of the ICW we have seen, with 7 to 8 feet of tidal range, it is very easy to plan your transit with plenty of water.
Northbound we find that the anchorage at Duplin Creek is a nice place to stay, good shore access at a dinghy dock and miles of roads to hike. It is 40 nautical miles south of Hell gate and is a good staging point for ... Read More
Little River SC, to Cape Lookout NC
Mason Inlet Crossing STM 280
The coastline between Little River and Cape Lookout faces south and east. Whether it is the prevailing southeasterly or stormy nor’easters, this coastline is a lee shore with big waves and surf. The shallow grade of the beach creates a wave break which is much sought by surfers. These same conditions, create longshore sediment transport, and as the sand moves along the coast, propelled by the relentless wave action, at each break in the beach sand is pushed inland towards the ICW. Veteran ICW cruisers have watched ... Read More
There is a 5 foot shallow spot in the ICW about 0.3 miles south of G117A near Sullivans Island . Heading south last November we found the shoal and marked it. Coming north March 28, I was looking for it to get an update. I was proceeding at about 4 knots because the state of the tide was 0.1 foot below dead low water, and we draw 4.5 feet. A sailboat from Maine was catching up to me. I called him on the VHF to let him know there was a shoal ahead. He said he was well aware of ... Read More
The chart below covers this shallow stretch. It starts at G47 Awendaw Creek and ends at G35A Jeremy Creek, McClellanville. From G47 to R42 just stay in visual center to have depths of 8 to 20 feet MLLW. Between R42 and G39 we saw several spots showing as little as 6.5 feet and we had +3.1 of help. This means that these areas would have 3.5 feet MLLW. Through this stretch we attempted to follow the best available water as shown on the Sonar Charts. That seemed to bring us right down the visual center of the channel. We ... Read More
Just before you get to the Savannah River, there is new shoal building. It was first noted in the fall of 2017. As you pass G39 and R40 there are reports of shoaling near the red. It is recommended that you stay on the green side if your draft is over 6 feet. On our track on the green side we saw 7.3 feet MLLW.
