About Blue Marlin Fishing in Charleston
The ultimate big game fish. Spectacular fighters that can exceed 1,000 pounds.
Blue Marlin are the ultimate big game fish — the apex predator of the open ocean. These magnificent billfish can exceed 1,000 lbs and are found in warm, blue water worldwide. Their cobalt-blue back, silver-white belly, and prominent bill (upper jaw extension used for slashing through bait schools) make them unmistakable. When hooked, blue marlin are spectacularly acrobatic — greyhounding across the surface and launching themselves fully airborne, sometimes multiple times. Catching a blue marlin on rod and reel is considered one of fishing's ultimate achievements.
Scientific name: Makaira nigricans

How to Catch Blue Marlin in Charleston
Techniques & Bait
Trolling large skirted lures (Moldcraft, Black Bart, Marlin Magic) in a spread behind the boat at 8-10 knots is the standard technique. Live bait trolling with large skipjack tuna, bonito, or blue runners under a bridge-mounted bait and switch setup targets the largest fish. Dredges (underwater teasers with hookless bait) are used to attract marlin to the spread. Pitch baiting — pulling a teaser close to the boat to draw in a marlin, then pitching a live bait — is the most exciting technique for experienced crews.
Recommended Tackle
80-130 lb class conventional trolling gear, roller guides, 80-130 lb monofilament, heavy cable leaders, size 10/0-12/0 hooks. Stand-up gear for experienced anglers. Fighting chair for fish over 500 lbs.
Best Deep Sea Fishing Fishing Spots in Charleston
Top spots where local captains target blue marlin and other deep sea fishing species.
The Charleston Bump (Gulf Stream)
The Charleston Bump is a dramatic underwater plateau that deflects the Gulf Stream eastward and creates one of the most unique offshore fishing environments on the Atlantic coast. The upwelling generated by the Bump concentrates swordfish, yellowfin tuna, wahoo, mahi-mahi, and blue marlin in remarkable densities. Charleston is internationally recognized as a premier swordfish port largely because of this geological feature.
The Snowy Wreck
The Snowy Wreck is a well-known artificial reef and sunken vessel lying in deep water offshore of Charleston, attracting large concentrations of snowy grouper, tilefish, and other deepwater bottom dwellers. Amberjack and barracuda hold above the wreck structure, while occasional wahoo and king mackerel pass through the area. It is a favorite destination for anglers targeting deep-drop species on full-day and overnight trips.
The 60-Mile Grounds
The 60-Mile Grounds refer to a productive stretch of ledges and hard bottom along the continental shelf edge approximately 60 miles southeast of Charleston. Vermilion snapper, triggerfish, amberjack, gag grouper, and scamp are pulled from the deep structure, while the proximity to the Gulf Stream brings pelagic action above the reef. This area serves as a transition zone between bottom fishing and bluewater trolling.
The Georgetown Shelf Break
The shelf break northeast of Charleston drops from approximately 100 feet to over 300 feet in a short distance, creating a wall of structure that holds an incredible diversity of deepwater species. Warsaw grouper, snowy grouper, tilefish, and golden crab are targeted with deep-drop rigs along the ledges. The break also produces quality yellowfin tuna and wahoo when the Gulf Stream pushes close.
