Fullday offshore fishing targeting tuna and mahi at Marathon HumpsEighthour trip includes trolling and jigging techniques for pelagic species20% gratuity included with professional mates aboard Infinite Blue Charters
If you're looking for top-rated offshore fishing in the Florida Keys, this full-day Marathon charter delivers everything you want in a world-class fishing adventure. Infinite Blue Charters runs an 8-hour trip that starts at 7:00 AM sharp, giving you prime time on the water when fish are most active. We're heading straight to the Marathon Humps - one of the most renowned fishing grounds in South Florida where the action never stops. This trip accommodates up to 6 anglers, so you'll have plenty of room to work without feeling crowded. Fair warning though - weather calls the shots out here, so we'll only head out when conditions are safe and fishable.
The Marathon Humps are legendary for a reason. These underwater structures sit in deep blue water about 15-20 miles offshore, where the Gulf Stream brings in massive schools of pelagic fish. You'll be fishing in 600-800 feet of crystal-clear water with incredible visibility on calm days. The boat ride out takes about an hour, but once you see those lines screaming off the outriggers, you'll know it was worth the run. We're talking serious fishing here - not the shallow water stuff you might be used to. The gratuity for our mates is already built into your trip cost at 20%, which is standard practice and covers the crew that's going to work their tails off getting you hooked up all day. These guys know the water like the back of their hand and they're the ones who'll be rigging your baits, gaffing your fish, and keeping you in the action.
This trip is all about two proven techniques that consistently produce fish on the Humps. We'll start with a spread of trolling lures - usually a mix of ballyhoo, cedar plugs, and diving plugs that cover different depths in the water column. The trolling spread lets us cover water efficiently while we're looking for birds, bait, and temperature breaks that hold fish. Once we mark schools or structure, that's when the jigging rods come out. Vertical jigging with heavy metal jigs is deadly effective on these deep structures, especially when fish are holding tight to the bottom. The crew will have you set up with the right tackle for both techniques - typically 30-50 pound class gear that can handle the long runs these fish are famous for. Don't worry if you've never jigged before - the mates will show you the technique and get you dialed in quickly.
Mahi Mahi, also called Common Dolphinfish, are the bread and butter of Marathon offshore fishing. These fish are pure adrenaline - they hit hard, jump high, and fight until the bitter end. Mahi typically range from 10-30 pounds out here, though bigger bulls pushing 40+ pounds show up regularly. They're most active from late spring through early fall, but you can find them year-round in South Florida. What makes mahi so special is their aggressive nature and willingness to eat both trolled baits and jigs. Once you hook one, there's often more in the area, so we'll usually stay put and work the school until they move on. The electric colors on these fish - brilliant yellows, greens, and blues - make them one of the most beautiful catches you'll ever boat.
Blackfin Tuna are the other star of the show, and they're pound-for-pound some of the hardest fighting fish in the ocean. These speedsters typically run 15-25 pounds and they're built like torpedoes - all muscle and attitude. Blackfins are year-round residents on the Marathon Humps, but they're most consistent during the cooler months when bait is thick. They respond well to both trolling and jigging, though they can be picky eaters when the bite gets tough. What anglers love about blackfins is their raw power - they'll take you deep into your backing and test every knot you tied. Plus, they're fantastic table fare if you're looking to take some fish home for dinner.
The Marathon Humps consistently produce some of the best offshore fishing in the Florida Keys, and this 8-hour trip gives you the time you need to make it count. Starting at 7:00 AM means we're on the fishing grounds before the afternoon wind picks up, and 8 hours gives us flexibility to move around and find the bite. Remember to bring your own food and drinks since meals aren't included - most anglers pack a cooler with sandwiches, snacks, and plenty of water. The fishing grounds we're heading to are the real deal - this isn't a tourist trip, it's serious angling for serious fish. Weather permitting, this Marathon charter fishing trip delivers the kind of action that keeps anglers coming back season after season. Book your spot now and get ready to see why the Humps have such a reputation among offshore fishing enthusiasts.
This 29-foot Wellcraft Coastal is built for serious offshore fishing at Marathon's legendary Humps. The boat features a massive 42-gallon baitwell that keeps your live bait swimming strong all day, plus dual fish boxes to store your tuna and mahi haul. Flush-mounted rod holders line the gunwales for clean trolling spreads, while the spacious helm accommodates all the electronics you need to mark fish and navigate these productive waters. When you're not fighting fish, stay comfortable with onboard A/C, a full galley for meal prep, and cold storage to keep drinks icy. The fish finder helps locate schools in the deep blue, and GPS keeps you on the most productive spots. With room for six anglers and a head onboard, this Wellcraft handles full-day trips to the offshore grounds where the big pelagics roam. The boat's design makes landing fish easier with plenty of cockpit space for the fight and proper storage for your catch.
Thunnus AtlanticusBlackfin tuna are the smallest of the tuna family but don't let that fool you - they pack serious fight into their 10-20 pound frames. These dark-bodied speedsters have beautiful bronze highlights and that classic tuna build built for speed. You'll find them in open water near continental shelves, usually in schools mixed with skipjacks. Fall through spring is prime time here in the Keys when water temps hit their sweet spot. What draws anglers to blackfins is their incredible stamina - they'll make blistering runs and test your drag like fish twice their size. They're also top-shelf table fare, perfect for sashimi or searing. The trick with blackfins is scaling down your tackle - use lighter fluorocarbon leaders and smaller circle hooks since they're spooky and have sharp eyes. When you find a school, work it fast because they move quickly through an area.
Coryphaena HippurusMahi are some of the most colorful fish you'll see out here - brilliant gold sides with electric blue and green backs that put on a light show when they come out of the water. They typically run 15-29 pounds, though we've seen some real bulls push 40+ pounds. You'll find them around floating debris, weedlines, and current breaks in open water, usually near the surface. Spring through fall gives us the best action when water temps stay warm. What makes mahi so popular is their acrobatic fight - they'll jump, run, and give you a real workout on medium tackle. Plus, they're fantastic eating with firm, white meat that's perfect on the grill. Pro tip: when you hook one, keep the boat moving and look for more fish - mahi travel in schools, so where there's one, there's usually several more waiting.
