I apologize, but there seems to be an error in your question. Griffins Landing 10400 is not located in North Carolina, but rather in Horry County, South Carolina.

Griffins Landing 10400 is a public boat ramp located on the Waccamaw River, which is a major waterway in southeastern North Carolina and northeastern South Carolina. The boat ramp is approximately 20 feet wide and offers access to the river for various types of watercraft, including kayaks, canoes, small motorboats, and pontoon boats.

According to the latest information available, the boat ramp is in good condition and is regularly maintained by the Horry County Parks and Recreation Department. Users are advised to exercise caution when launching and retrieving their boats, as the river can be swift and shallow in some areas.
