Marathon's Best Offshore Charter Fishing

Ready to chase big game fish in the deep blue waters off Marathon, Florida? Our private 6 to 8-hour offshore charters are your ticket to world-class fishing action. We'll cruise 20-30 miles out where the Gulf Stream brings in monster pelagics like mahi, tuna, and billfish. Whether you're a seasoned pro or it's your first time wetting a line, our experienced crew will put you on the fish and make sure you have a blast. Let's get out there and make some memories!

What to Expect on the Water

We kick things off bright and early at 7:30 AM, giving us plenty of time to reach the offshore fishing grounds. You've got two options: a 6-hour 3/4 day trip or the full 8-hour experience. Once we're in the zone, it's all about finding the fish. We'll be trolling, live baiting, and maybe even doing some kite fishing if conditions are right. The Marathon area is known for its variety - one minute you could be battling a hard-fighting mahi, the next you might have a wahoo screaming off line or a sailfish tail-walking across the surface. It's non-stop action that'll keep everyone on their toes.

Techniques & Tackle Talk

Offshore fishing is a whole different ballgame from inshore, and we've got the gear to match. We're talking heavy-duty rods and reels spooled with hundreds of yards of line. For trolling, we'll be pulling a spread of lures and maybe some rigged ballyhoo. When we mark fish on the sounder or spot a weedline, we might switch to live bait tactics. Don't worry if you're new to this - our crew will walk you through everything from setting the drag to proper fighting technique. And hey, if you're an old salt, feel free to share your tips. There's always something new to learn out here.

Top Catches This Season

The fishing has been on fire lately. We've been seeing some real beauties come over the rail. Mahi mahi have been thick, with lots of "gaffers" (fish big enough to need a gaff to land) in the 15-30 pound range. The tuna bite has been steady too, mostly blackfin but we've tangled with a few yellowfin pushing 50 pounds. And let's not forget the billfish - we've released several sailfish and even a couple of white marlin this month. It's the kind of fishing that keeps you coming back for more.

Species You'll Want to Hook

Mahi Mahi (Dorado): These neon-colored acrobats are a favorite for good reason. They hunt in packs near floating debris and weedlines, often skyrocketing out of the water when hooked. Mahi can grow over 50 pounds, but even the smaller "schoolies" put up a great fight and taste amazing. They're around all year but peak from April to September.

Wahoo: Speed demons of the sea, wahoo are like underwater torpedoes. They're notorious for blistering runs that can empty a reel in seconds. We target them by high-speed trolling with specialized lures. Fall and winter are prime wahoo season, but you can luck into one any time of year. Landing a 'hoo is always a highlight of any trip.

Yellowfin Tuna: Pound for pound, yellowfin might be the strongest fish in the ocean. These muscular torpedoes will test your stamina and your tackle. We find them around offshore structure and current edges, often mixed in with blackfin tuna. Spring and fall are the best seasons, but we catch them year-round. There's nothing like fresh yellowfin sashimi at the end of a long day.

Striped Marlin: While not as common as their Atlantic blue marlin cousins, hooking into a striped marlin is always a possibility here. These majestic billfish are known for their incredible aerial displays and can reach lengths of over 10 feet. They're a true bucket list catch for any angler. We typically encounter them in the warmer months from late spring through early fall.

Atlantic Sailfish: The sailfish is the sprint champion of the ocean, capable of short bursts over 60 mph. Known for their spectacular leaps and that unmistakable sail-like dorsal fin, these billfish are a blast to catch on light tackle. We often find them hunting ballyhoo or flying fish near the surface. Winter and early spring are peak sailfish season, but we catch them year-round.

Why Anglers Keep Coming Back

There's something special about offshore fishing in the Florida Keys. Maybe it's the crystal-clear water or the anticipation of what might grab your bait next. Our repeat customers tell us it's the whole package - the thrill of the hunt, the rush when a big fish hits, and the satisfaction of bringing dinner back to the dock. Plus, there's nothing like spending a day on the water with good company, swapping stories and making new ones. Whether you're after a trophy for the wall or just want to fill the cooler, our offshore trips deliver the goods time and time again.

Time to Book Your Spot

If you're itching to bend a rod and feel that offshore magic, don't wait to book your trip. Our calendar fills up fast, especially during peak seasons. Remember, we're offering both 6-hour and 8-hour options to fit your schedule and fishing goals. All the gear is provided, so you just need to bring your sense of adventure (and maybe some snacks). Whether you're a solo angler looking to join a group or want to charter the whole boat for your crew, we've got you covered. Let's make it happen - those big fish aren't going to catch themselves!

Atlantic Sailfish

Atlantic sailfish are some of the most exciting gamefish out there. These speedsters average around 7 feet long and 50 pounds, but can top 10 feet and 140 pounds. You'll find them in warm waters from 30-65 feet deep, though they can dive much deeper when hunting. Winter's the prime time to target sailfish in the Florida Keys. They're known for their incredible fights - leaping and diving repeatedly. Be ready for an endurance battle when you hook one. Most anglers troll for sailfish, but fly fishing for them is gaining popularity too. Either way, use bright pink and white or blue and white lures to catch their eye. Squid and mackerel make good bait choices. One local trick: When a sailfish takes the bait, let it run before setting the hook. They tend to shake their heads at first to dislodge it. Wait for that solid run, then hang on tight!

Atlantic Sailfish

Mahi Mahi or Common Dolphinfish

Known for their vibrant colors and acrobatic fight, Mahi Mahi are a favorite among offshore anglers. These fast-growing fish thrive in warm waters and are often found near floating debris or weed lines. They’re not only exciting to catch but also highly prized for their mild, delicious meat. Perfect for both sport and table fare, Mahi Mahi are a highlight of any deep sea trip.

Striped Marlin

Striped Marlin are one of the most sought-after billfish in offshore sportfishing. Known for their striking blue stripes and energetic fight, they often leap spectacularly when hooked. These powerful predators inhabit deep Pacific waters and are typically caught by trolling. Anglers prize them for the challenge they present and the unforgettable experience of the battle.

Striped Marlin

Wahoo Fish

Wahoo are fast, aggressive predators known for their speed and razor-sharp teeth. Found in offshore waters, they’re a top target for sport anglers thanks to their hard strikes and powerful runs. Their sleek, torpedo-shaped bodies feature striking vertical stripes and make them one of the fastest fish in the ocean. Wahoo are not only thrilling to catch but are also highly prized for their delicious, firm white meat.

Wahoo Fish

Yellowfin Tuna

Yellowfin Tuna are powerful pelagic fish prized for their strength, speed, and delicious meat. Known for their bright yellow fins and streamlined bodies, they’re often found in warm offshore waters. These tuna put up a serious fight, making them a favorite among experienced anglers. Whether you’re chasing big game or looking for a high-energy fishing day, Yellowfin Tuna offer an exciting challenge and an excellent reward on the grill or sashimi plate.
