About Cobia Fishing in Marathon
A powerful, curious fish often found near buoys, rays, and structure. Excellent eating and hard fighters.
Cobia are powerful, unique gamefish that look like nothing else in the ocean — a flat, broad head, single dorsal fin, and dark brown coloring with a distinctive black lateral stripe running from head to tail, with lighter stripes above and below. They are often found near buoys, rays, sea turtles, and other large objects, using them as shade and ambush cover. Cobia are curious fish that will approach boats, and sight-casting to cruising cobia is one of the most exciting experiences in inshore/nearshore fishing.

How to Catch Cobia in Marathon
Techniques & Bait
Sight-casting to cobia following rays or cruising near buoys is the premier technique — throw a live eel, large live crab, or large jig directly in front of a cruising fish. Live eels are the #1 bait. Large jigs (1-2 oz) in brown, white, or chartreuse bounced near structure work well. Chumming with cut baitfish over wrecks and reefs draws cobia up from the bottom. During the spring migration, anchoring near channel markers and buoys with live bait (pinfish, crabs) catches fish as they migrate along the coast.
Recommended Tackle
Medium-heavy spinning or conventional rod (7 ft), 5000-6000 reel, 20-30 lb braid, 40-60 lb fluorocarbon leader, 5/0-7/0 circle hooks. Cobia make blistering initial runs — make sure your drag is set properly.
Best Nearshore Fishing Spots in Marathon
Top spots where local captains target cobia and other nearshore species.
Sombrero Reef
Sombrero Reef is a massive coral reef formation marked by the Sombrero Key Lighthouse approximately 4 miles south of Marathon. The reef supports one of the healthiest coral communities in the Keys with excellent fishing for yellowtail snapper, mutton snapper, hogfish, and grouper. It is the premier nearshore reef-fishing destination from Marathon.
Coffins Patch
Coffins Patch is a large patch reef complex between Sombrero Reef and the shore, offering productive fishing in 10-25 feet of water. Yellowtail snapper, mangrove snapper, lane snapper, and hogfish hold on the scattered coral heads and reef structure. The shallow depth and proximity to Marathon make it ideal for shorter fishing trips.
Delta Shoals
Delta Shoals is a shallow reef area south of Marathon where sand flats meet the reef line, creating habitat for a variety of species. Permit frequently cruise the sand channels adjacent to the reef, while yellowtail snapper and mutton snapper hold on the coral structure. The area is known for producing large permit on the shallow flats near the reef.
Marathon Reef (Marker 48)
The reef line near Channel Marker 48 south of Marathon features productive coral formations in 20-40 feet of water. Yellowtail snapper, mutton snapper, hogfish, and black grouper are the primary targets on the reef ledges and coral heads. The deeper edges attract kingfish and cobia during seasonal migrations along the reef line.
