The seasonal picture for the wider coast is in the Atlantic Southeast cobia guide (see also the Atlantic Southeast region guide).
Where boats run: grounds and structure


Cobia fishing out of Darien runs from beach reefs 2.5 nautical miles off Blackbeard Island in 10 to 16 ft to the R2 Navy tower, 38 nautical miles east of Sapelo Island in 72 ft. Boats leave from the Darien port page area and reach the Atlantic through Doboy Sound. Blackbeard Island and Sapelo Island are the reference landmarks for most distances.
The grounds below are listed roughly by distance, from the Doboy Sound entrance out to the long runs. Each distance is measured from the landmark its source uses, so the figures don’t share a single starting point. Chart layers are not for navigation.
| Ground | Type | Depth | Distance | Landmark |
|---|---|---|---|---|
| Old D buoy | buoy | n/a | about 2 miles | Doboy Sound entrance |
| BH reef | beach reef | 10 to 16 ft | 2.5 nm east | Blackbeard Island |
| BL reef | beach reef | 9 to 15 ft | about 3 nm | n/a |
| KTK reef | offshore artificial reef | 35 to 45 ft | 7 nm east | Blackbeard Island |
| J reef (JY) | n/a | n/a | n/a | n/a |
| Gray’s Reef NMS | sanctuary | n/a | n/a | n/a |
| Middlegrounds 70-foot spot | n/a | 70 ft | n/a | n/a |
| R2 Navy tower | tower | 72 ft | 38 nm east | Sapelo Island |

Charters that list cobia
Two operators list cobia for anglers who want to fish out of Darien on someone else’s boat. Reel Busy Shark Charter runs with Captain Billy Stafford. Coastal Ga Fishing, which has boats at Shellman Bluff, also lists the species.
