Marathon Offshore & Inshore Fishing Charter
Looking for a top-rated fishing charter that delivers both variety and action? Captain Craig and the Fun In The Sun Charters crew know exactly where to find the fish in Marathon's prolific waters. This full-day adventure targets some of the Florida Keys' most prized species, from hard-fighting grouper on offshore structure to acrobatic mahi mahi in blue water. With all gear and licenses included, you'll focus on what matters most – putting fish in the boat and making memories that last.
What to Expect on the Water
Your fishing day kicks off around 7:30 a.m. when Captain Craig fires up the engines and heads out from Marathon's docks. The early start gives you maximum time on the fishing grounds, whether that's working offshore wrecks and reefs for grouper and snapper or trolling the deeper waters for mahi mahi and kingfish. The boat accommodates up to four anglers comfortably, creating an intimate atmosphere where everyone gets plenty of shots at fish. Captain Craig's local knowledge shines as he reads conditions and adjusts tactics throughout the day, moving from structure to structure or switching from bottom fishing to trolling based on what's biting. The first mate works hard to keep lines in the water, bait fresh, and the fish box full – just remember that 20% gratuity is customary for their efforts. You're welcome to pack your own lunch and snacks, or grab a convenient box lunch from 7 Mile Grill before departure.
Techniques and Tackle
This charter combines the best of both offshore and inshore fishing techniques to maximize your catch variety. On the offshore grounds, you'll drop heavy tackle to target grouper and snapper around wrecks, ledges, and hard bottom structure in 60 to 150 feet of water. Circle hooks with fresh cut bait or live pinfish are the go-to setup for these bottom dwellers. When conditions allow, Captain Craig runs trolling spreads with ballyhoo, bonito strips, and diving plugs to intercept mahi mahi, kingfish, and other pelagic species moving through the area. The inshore component focuses on lighter tackle around bridges, channels, and shallow reefs where redfish, yellowtail snapper, and mangrove snapper congregate. All rods, reels, terminal tackle, and bait are provided, along with your Florida fishing license. The boat carries a full complement of gear from heavy conventional reels for big grouper to spinning outfits perfect for finicky yellowtails.
Customer Stories
"Captain Craig was an excellent charter captain and put us on fish all day. He also gave excellent recommendations on where to take the fish to have it prepared. We also hired him to take our family to a sandbar and to take my younger kids fishing. We had a ton of fun at a gorgeous sand bar where we spent several hours playing in the unbelievably beautiful area. He then took us to a spot perfect for fishing with young children. My eight year old son caught lots of fish and had the time of his life. Thank you for a great time Capt. Craig!" - Jordan
Species You'll Want to Hook
Black grouper represent the heavyweight champions of Marathon's offshore scene, with fish ranging from 10 to 50 pounds common around the deeper wrecks and ledges. These powerful fighters make blistering runs toward structure when hooked, testing both tackle and angler skill. Peak season runs from late spring through early fall when they're most active in 80 to 200 feet of water. What makes black grouper special is their incredible table fare – firm, white meat that's perfect for grilling or blackening. The fight combined with the feast makes them a customer favorite trip after trip.
Gag grouper offer slightly different challenges, typically found in shallower waters around 40 to 100 feet on rocky bottom and artificial reefs. These fish average 5 to 20 pounds and are known for their aggressive strikes and dogged fights close to the bottom. Winter months often produce the best gag action as they move into shallower spawning areas. Their distinctive mottled coloration and broad tail make them easy to identify, while their mild flavor appeals to even the pickiest eaters in your group.
King mackerel, or kingfish as locals call them, bring speed and excitement to every charter. These silver bullets patrol the offshore waters from spring through fall, with the best action typically in 60 to 150 feet of water. Kings average 10 to 30 pounds but can reach 50-plus pounds, making screaming runs that peel line off reels. They're perfect for trolling with live bait or high-speed lures, and their aggressive nature means multiple hookups are common. The meat is excellent smoked or grilled, with a rich flavor that's distinctly different from reef fish.
Redfish add an inshore element to your fishing adventure, lurking around bridges, channels, and shallow flats throughout Marathon's backcountry. These copper-colored fighters average 5 to 15 pounds and are famous for their bulldogging runs and never-give-up attitude. Redfish bite year-round but peak during fall months when they school up for spawning. What sets them apart is their willingness to eat everything from live shrimp to cut bait, making them perfect targets when you want consistent action.
Mahi mahi, also called dolphinfish or dorado, represent pure excitement on the offshore grounds. These brilliant yellow-green fish travel in schools around floating debris, sargassum lines, and temperature breaks in blue water. Size ranges from schoolie dolphins around 5 pounds to impressive bulls over 30 pounds. Spring and summer offer peak mahi action as they follow the Gulf Stream closer to shore. Their acrobatic fights feature spectacular jumps and blazing runs, while the firm, white meat ranks among the best eating fish in the ocean. When you find one mahi, there are usually more nearby, leading to fast action and full fish
