About Blue Marlin Fishing in Swansboro
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 Swansboro
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 Swansboro
Top spots where local captains target blue marlin and other deep sea fishing species.
Gulf Stream (Onslow Bay)
The Gulf Stream is accessible from Swansboro in approximately 35 to 45 miles via Bogue Inlet, with productive bluewater fishing along the Stream's western edge. Blue marlin, yellowfin tuna, mahi-mahi, wahoo, and sailfish are targeted along temperature breaks and weed lines. The Crystal Coast's relatively close Gulf Stream access makes full-day bluewater trips feasible from Swansboro.
AR-370 Offshore Reef
AR-370 is an offshore artificial reef site in Onslow Bay, deployed with structure in 60 to 90 feet of water to attract reef fish species. Grouper, red snapper, amberjack, triggerfish, and large black sea bass hold on the deployed materials. It is a productive full-day bottom-fishing destination for Swansboro-based charter boats.
Onslow Bay Ledges
Natural rock ledges along the Onslow Bay continental shelf create bottom relief that concentrates gamefish in otherwise featureless sandy bottom. King mackerel, amberjack, grouper, and barracuda hold along these ledges, which range from 60 to 120 feet deep. Trolling the ledge edges while dropping baits to the bottom produces diverse catches of reef and pelagic species.
Spar Wreck
The USS Spar is a decommissioned Coast Guard cutter sunk as an artificial reef in approximately 110 feet of water in Onslow Bay. The 180-foot wreck attracts amberjack, grouper, barracuda, and black sea bass, while pelagic species cruise above the structure. It is one of the better-known wreck-fishing sites accessible from Swansboro on a full-day offshore trip.
