Key Largo Deep Sea Fishing: 6-8 Hour Adventure

Full Day Offshore Fishing in Key Largo

Key Largo's offshore waters are where serious anglers come to play. Local Grown Charters runs these full-day trips because we know where the big fish live – and trust me, they're out there waiting. You'll spend 6 to 8 hours chasing some of the Atlantic's most prized gamefish, from screaming sailfish to bull mahi that'll test your arms. Our boat handles up to four guests, so you're not fighting crowds for rod space or photo ops. Whether you've been fishing offshore for decades or this is your first time past the reef line, our crew knows how to put you on fish and keep the action hot all day long.

What to Expect on the Water

We're talking about real offshore fishing here – not some half-day run to the near reef. These trips take you into the deep blue where the Gulf Stream brings in the big pelagics. You'll be running lines in 200 to 1,000 feet of water, where the bottom drops away and the ocean comes alive. The ride out takes about 45 minutes, giving you time to get your sea legs and watch the water change from that shallow turquoise to deep blue. Our crew sets up multiple rods with different techniques running simultaneously – you might have live bait down deep while trolling lures on the surface. When something hits, you'll know it. These fish don't nibble; they slam the bait and take off like freight trains. The boat stays busy all day, with our crew constantly adjusting based on what we're seeing on the electronics and where the birds are working.

Trolling Tactics & Gear Setup

Most of your day revolves around trolling – covering water with a spread of lures and baits that imitate what these pelagic species hunt. We run a mix of ballyhoo, bonito strips, and artificial lures at different depths and distances from the boat. The outriggers keep lines spread wide, while we might drop back a flat line or run something deeper on a planer. When we find structure or temperature breaks, we'll switch to live bait fishing – pilchards, goggle eyes, or whatever we can catch fresh. The rod setup depends on what we're targeting, but expect heavy spinning gear and conventional reels loaded with enough line to handle long runs. Our crew handles all the rigging, net work, and fish handling so you can focus on the fight. When a fish comes to the boat, that's when the real teamwork starts – everyone has a job, and our guys know exactly how to get your fish in the boat safely.

Target Species You'll Want to Hook

Atlantic Sailfish are the crown jewel of Key Largo offshore fishing. These acrobatic billfish average 6 to 8 feet and put on an air show that'll leave you breathless. Peak season runs from December through April when they migrate through our waters in impressive numbers. Sailfish hit fast-trolled ballyhoo and artificial lures, often coming up behind the boat with their sails lit up electric blue. The fight combines blistering runs with spectacular jumps – they'll clear the water completely, shaking their heads and gill-rattling to throw the hook.

King Mackerel patrol these offshore waters year-round, with fish ranging from schoolie-sized "snake kings" to true giants over 40 pounds. The big fish show up best from fall through early spring, often relating to temperature breaks and bait schools. Kings hit trolled spoons, live pilchards, and slow-trolled dead baits. They make screaming initial runs that'll burn line off your reel, then fight with surprising stamina for their size. A big king coming to the boat is all muscle and teeth – definitely a fish that demands respect.

Mahi Mahi bring the color and chaos that makes offshore fishing addictive. These brilliant fish travel in schools under floating debris, weed lines, or current breaks. Small mahi start showing up in spring, with the bigger bulls arriving through summer and fall. They hit everything from small jigs to large trolling lures, often in multiples when you find a good school. Bulls can top 30 pounds and fight with incredible aerial displays, while their electric colors fade through the entire spectrum as they come to the boat.

Wahoo are the speed demons of the offshore world, capable of runs that'll smoke your reel in seconds. These fish prefer the deeper water and stronger current, often showing up around 400 feet and beyond. Wire leaders are essential because their razor-sharp teeth slice through mono like butter. Wahoo average 20 to 40 pounds in our waters, with occasional fish pushing 60. They hit high-speed trolled lures and ballyhoo, making initial runs that are absolutely devastating.

Great Barracuda grow impressive in the offshore environment, with fish over 20 pounds common around structure and temperature breaks. While smaller barracuda inhabit the flats, these offshore fish are built for speed and power. They'll hit both live bait and trolled lures, making slashing attacks that often result in spectacular jumps. Their teeth require wire leaders, and landing a big barracuda requires careful handling.

Bluefin Tuna represent the ultimate offshore challenge when they push through Key Largo waters during their migrations. These powerful fish demand heavy tackle and serious technique, often requiring live bait presentations or chunking. School fish run 20 to 40 pounds, but larger fish are always possible. Bluefin fight with incredible power and stamina, making long runs and testing your endurance.

African Pompano are among the most underrated gamefish in our offshore waters. These deep-bodied fish fight way above their weight class, using their broad sides to leverage against the current. They're often found around deeper structure and drop-offs, hitting both live bait and jigs. African pompano have incredible table value and put up fights that surprise even experienced anglers.
