Looking for the real deal when it comes to offshore fishing in the Florida Keys? This full-day Marathon charter with Infinite Blue Charters puts you right where the action is. We're talking about an 8-hour adventure that starts at 7:00 AM and takes you straight to the Marathon Humps – one of the most productive fishing grounds in South Florida. With space for up to 6 anglers, this trip is perfect for families, groups of friends, or anyone serious about hooking into some quality fish. The best part? Your mate's gratuity is already covered, so you can focus on what matters most – fighting fish and having a blast on the water.
When you step aboard at dawn, you'll immediately notice the difference between inshore fishing and what we do out here. The ride to the Marathon Humps takes us into deep blue water where the bottom drops off dramatically, creating the perfect environment for pelagic species. These underwater mountains and ledges act like magnets for baitfish, and where there's bait, there are hungry predators. The captain and crew know these waters like the back of their hands – they've been working these same spots for years, reading the currents, water temperature, and bird activity to put you on fish. Weather plays a huge role in offshore fishing, so trips are weather-dependent for your safety and success. Trust me, you'd rather reschedule than fight seasickness all day when the conditions aren't right.
This isn't your typical drift fishing or bottom bouncing – we're using two primary techniques that are absolutely deadly on tuna and mahi. Trolling is our bread and butter out here, running a spread of lures and baits at different depths and distances behind the boat. The crew will set up everything from surface plugs to deep-diving lures, covering the entire water column. When we mark fish on the sounder or spot diving birds, that's when we break out the jigs. Vertical jigging over structure is hands-down one of the most effective ways to trigger strikes from aggressive fish holding tight to the bottom. The gear is all top-shelf stuff – heavy spinning reels spooled with braid, conventional reels for trolling, and a selection of jigs and lures that have proven themselves time and again in these waters. Don't worry if you've never jigged before; the crew will walk you through the technique and help you dial in the right cadence.
Mahi mahi, also called common dolphinfish, are absolutely spectacular fighters and one of the most sought-after species in these waters. These fish are pure muscle and acrobatics – when a mahi hits your line, you'll know it immediately. They're famous for their long runs and spectacular jumps, often clearing the water multiple times during the fight. Mahi typically range from 10 to 30 pounds in these waters, though bulls over 40 pounds are always a possibility. The best action usually happens from late spring through early fall when water temperatures are warm and these fish follow the weed lines and debris. What makes mahi so special is their willingness to bite almost anything – they're curious, aggressive, and once you find a school, you can often catch multiple fish before they disappear. The meat is absolutely fantastic too – white, flaky, and perfect for the grill.
Blackfin tuna are the other main target, and these fish will test your endurance and equipment. Don't let their smaller size fool you – blackfins are pound-for-pound some of the strongest fish in the ocean. These torpedoes typically run 5 to 15 pounds, but what they lack in size they make up for in pure determination. They'll peel drag off your reel like it's nothing and fight all the way to the boat. Blackfins are year-round residents around the Marathon Humps, but the bite really turns on during the cooler months when they school up in larger numbers. They're incredibly fast and have incredible stamina thanks to their physiology – they can actually regulate their body temperature, making them perfectly adapted for life in the open ocean. Jigging is particularly effective for blackfins, especially when they're holding tight to structure. The sashimi-grade meat is a huge bonus – many anglers consider blackfin tuna to be superior to yellowfin for raw preparations.
The Marathon Humps don't give up their secrets easily, but with experienced guides, proper techniques, and a full day on the water, you've got all the ingredients for an outstanding fishing trip. This isn't a half-day run where you're heading back to the dock just as the bite gets good – 8 hours gives you time to explore different areas, try various techniques, and really capitalize when you find active fish. The 20% mate gratuity being included means one less thing to worry about, and these guys work hard to put you on fish and keep your lines in the water. Weather can change quickly out here, so having a captain who prioritizes safety while still maximizing your fishing opportunities is worth its weight in gold. Whether you're an experienced offshore angler or looking to step up from inshore fishing, this Marathon charter delivers the kind of action that keeps you coming back for more. Book your spot now and get ready to experience some of the best offshore fishing the Florida Keys has to offer.
This Wellcraft 290 Coastal is built for serious offshore fishing in Marathon's deep waters. The 42-gallon Kodiak Pro-Flow baitwell keeps your live bait healthy and active, while the paired fish boxes provide plenty of space for your tuna and mahi haul. Flush-mounted rod holders keep your gear secure during the ride to the Marathon Humps, and the spacious helm accommodates all the electronics you need - GPS, fish finder, and more. With AC to beat the Florida heat, a full kitchen, refrigerator, and icebox for cold drinks, plus an onboard head, you've got everything covered for a comfortable 8-hour fishing adventure. The boat handles 6 anglers with room to move around while trolling and jigging for pelagics. Perfect for targeting those prized tuna that make the Marathon Humps famous among serious fishermen.
Thunnus AtlanticusBlackfins are the scrappiest small tuna you'll find around here, averaging up to 39 inches and putting up fights way bigger than their size suggests. These fish love the warm waters near the continental shelf and are perfect for our Marathon Humps trips. Fall through spring gives you the best shot at them in our area. What makes blackfins special is their fierce fighting spirit - they'll test every knot and drag setting you've got. The meat is top-notch too, with that rich tuna flavor that's perfect fresh or for sashimi. Here's the key: scale down your tackle. These fish have sharp eyes, so use 30-pound fluorocarbon leaders and 5/0 circle hooks. Vertical jigging works great, but don't overlook live pilchards for chum - they'll bring the whole school right to the boat.
Coryphaena HippurusMahi are some of the most colorful fish you'll see out here - brilliant gold and green that put on a real light show when they're fighting. These fast-growing fish average 15-29 pounds and love hanging around floating debris and weed lines near the Marathon Humps. They're incredible fighters with serious speed and acrobatics that'll test your tackle. Best action happens during warmer months when they school up in the offshore waters. The meat is fantastic - firm, white, and mild-tasting, perfect for the grill. Pro tip: when you hook one, keep your eyes peeled for others nearby. Mahi travel in schools, so where there's one, there's usually more. Use 30-50 pound tackle and make your baits skip on the surface - they can't resist anything that looks like a flying fish.
