Healy Report: Isle of Palms to Port Royal Landing, SC, AICW Statute Miles 457-539
This leg of Peg and Jim Healy’s voyage through South Carolina takes them through Charleston Harbor and south to Beaufort, home of CRUISERS’ NET SPONSORS, Downtown Marina and Port Royal Landing. The infamous Ashepoo-Coosaw Cut at Mile 517 is a Problem Stretch notorious for shoaling and channel shifting. And, as always, Cruisers’ Net is grateful to these experienced cruisers for sharing their observations and advice.
Sanctuary and crew cruised from Mt. Pleasant, Isle of Palms, to Beaufort, Port Royal Landing, on 10/18/2017.
Mt. Pleasant Range – The area from StM 460.0 to 460.5 is shoaling. We passed this area mid-channel at about 07h10, near high tide (+6.0), and saw 11.5 feet of water. The control depth would be 5-1/2 feet at low tide, less on a celestial low.
Dawho River, North Creek, Watts Cut – We transited this area between 11h50 and 12h15 (+3.0 –> +2.7 ft) and saw areas at 8.5 ft. The control depth for this area is about 5.5 feet at low tide, less on a celestial low.
Ashepoo-Coosaw Cut – This cut is in two parts; the north section that connects the Ashepoo River and Rock Creek and the South section that connects Rock Creek to the Coosaw River. The North cut is not a concern at this time. We transited the South section at 13h15, 1-1/4 hours before low tide (+0.5 ft). Favor “G181,” the outside radius of the curve there, and then favor red at the entrance, floating R”184.” Do not cut the corners here; follow the centerline of the cut out into the deeper water of the Coosaw River. There is a 5-1/2 ft sandpile at the entrance. We slowed for our passage, and never saw less than 5-1/2 ft.
Hope this is useful.
