Captain Bill's been running these Marathon waters for over 40 years, and he knows exactly where the fish are holding. When you step aboard with Billfish Sportfishing, you're getting more than just a fishing trip – you're tapping into decades of local knowledge that only comes from living and breathing these flats. Whether you choose the 5-hour, 6-hour, or 8-hour option, Captain Bill keeps his groups small at just 3 anglers max, so you get the personal attention that makes all the difference between coming home with stories and coming home with fish.
Your day starts early when Captain Bill picks his spots based on tide, wind, and what's been biting lately. The boat's rigged with quality rods, reels, and all the tackle you'll need – plus your fishing license is covered. Captain Bill runs a relaxed operation where beginners feel comfortable asking questions and experienced anglers can focus on technique. He'll put you on structure where the sheepshead hang out, work the mangrove edges for snook, and position you perfectly when tarpon start rolling. The atmosphere stays friendly and laid-back, but don't mistake that for lack of focus – this crew knows how to put fish in the boat. Fair warning though: deposits are non-refundable, so plan accordingly.
Captain Bill's got the gear dialed in for inshore fishing success. You'll be working with medium to medium-heavy spinning rigs loaded with circle hooks for the bigger stuff, and lighter tackle when finesse fishing is called for. Depending on what's running, you might be bouncing jigs along the bottom for sheepshead, casting live shrimp under the mangroves for snook, or working crabs and pinfish when the tarpon show up. The captain's tackle selection changes with the seasons – he knows when to switch from artificials to live bait, when to go heavy on the leader, and exactly which spots produce during different tide phases. You'll learn techniques that work specifically in these Marathon flats, not generic advice you can get anywhere.
Snook are the crown jewel of inshore fishing here in Marathon, and these ambush predators know how to use the mangrove structure to their advantage. They'll sit in the shadows waiting for baitfish to drift by, then explode on your offering with a strike that'll get your heart pumping. Best months are typically April through October, and a good snook will run anywhere from 5 to 15 pounds, though the occasional bull can push 20-plus. What makes them special is their fight – they'll make blistering runs toward structure and try every trick to throw your hook. Captain Bill knows the productive holes where these fish stack up during different tide phases.
Tarpon fishing in these waters is something every angler should experience at least once. These silver kings can reach 100 pounds or more, and when they hit your bait, the whole game changes. Peak season runs from April through August when they migrate through the area, but resident fish stick around year-round. What gets anglers hooked on tarpon isn't just their size – it's watching a 6-foot fish launch itself completely out of the water, gill plates rattling, trying to shake your hook. They're catch-and-release only, but that jumping, tail-walking fight creates memories that last a lifetime. Captain Bill positions the boat where tarpon travel, usually early morning or late afternoon when they're most active.
Sheepshead might not win beauty contests, but they're some of the tastiest fish swimming these flats, and catching them takes real skill. These black-and-white striped bottom dwellers hang around structure like docks, bridges, and rocky areas where they pick crustaceans and small fish. They're notorious bait thieves with their human-like teeth, so you need perfect timing to hook up. Peak season runs from November through March when they school up for spawning. A good sheepshead runs 2 to 8 pounds, and they fight harder than you'd expect for their size. Captain Bill knows the productive spots where these fish concentrate, and he'll teach you the subtle techniques needed to consistently hook these finicky feeders.
Captain Bill's calendar fills up fast, especially during prime fishing seasons, so don't wait around if you want to get in on this action. With over four decades guiding these Marathon waters, he's built a reputation among locals and visiting anglers who know quality when they see it. The small group size means personalized attention whether you're learning the basics or fine-tuning advanced techniques. Your fishing license, tackle, and Captain Bill's expertise are all included – you just need to show up ready to fish. Book your half-day or full-day adventure with Billfish Sportfishing and experience why anglers keep coming back to these productive Marathon waters year after year.
Archosargus ProbatocephalusSheepshead are the "convict fish" with their black and white stripes, but don't let their looks fool you - they're some of the best eating fish around. Most run 2-5 pounds with white, sweet meat that's hard to beat. You'll find them around any structure: docks, bridges, pilings, and reefs where they munch on barnacles and crabs. Winter months are prime time, especially February through April. They're notorious bait thieves with human-like teeth that can crush shells. What guests love is the challenge - they require finesse and quick hook sets. My advice: use small hooks with fresh shrimp and get as close to structure as possible. When you feel that subtle tap-tap, set the hook hard immediately.
Centropomus UndecimalisSnook are one of our most popular inshore targets around Marathon. These sleek fighters typically run 1-3 feet long with that distinctive black lateral line down their golden sides. You'll find them around mangroves, docks, and creek mouths where they ambush baitfish. They love structure and can handle both salt and fresh water. Best fishing happens May through September during their spawning season when their fins turn bright yellow. What makes snook special is their explosive strike and acrobatic jumps - plus they're great eating with firm white meat. Here's a local tip: when fishing around mangroves, cast right into the roots where most anglers won't go. That's where the big ones hide.
Megalops AtlanticusTarpon are the ultimate game fish - these silver giants can reach 6-8 feet and over 200 pounds, though most we catch run 80-100 pounds. They frequent the flats, channels, and deeper holes around the Keys from spring through fall. What sets them apart is their aerial show - they'll jump 10 feet out of the water trying to throw your hook. The fight can last an hour with multiple jumps. Most folks target them for the sport since they're bony and not great eating. Best months are May through August when they migrate through our waters. Pro tip: when a tarpon jumps, bow to the fish by dropping your rod tip - keeps tension off the line and prevents break-offs during those spectacular leaps.
