Full day offshore fishing targeting sailfish, tuna, and marlinExpert crew guidance for all experience levels aboardSix-person capacity trips from Islamorada waters
Nothing beats a full day chasing pelagics in the deep blue waters off Islamorada. Sea Horse Deep Sea Fishing knows exactly where to find the action, and their experienced crew will put you on some serious fish. We're talking about going after the big boys - sailfish, tuna, marlin, amberjack, and wahoo. This isn't your typical half-day trip where you're rushing back to the dock just as things heat up. With a full day charter, you've got time to work multiple spots, adapt to changing conditions, and really dial in on what's biting. The boat holds up to 6 anglers, so bring your crew or join a small group of fellow fishing fanatics.
Your day starts early - that's when the fish are most active and the seas are typically calmer. The Sea Horse crew knows these waters like the back of their hand, and they'll have you rigged up and ready before you even clear the harbor. Islamorada sits right in the heart of the Florida Keys, perfectly positioned for accessing both the Atlantic's deep drop-offs and the productive edge waters where baitfish congregate. The crystal-clear waters here aren't just pretty to look at - they're a sign of the healthy ecosystem that supports world-class offshore fishing. You'll be targeting structure, weed lines, and temperature breaks where predatory fish ambush their prey. The crew handles all the heavy lifting when it comes to reading conditions, but they're also great teachers if you want to learn the finer points of offshore fishing.
Most of your fishing will involve trolling with a spread of lures and baits designed to attract different species at various depths. The crew runs a combination of outriggers, downriggers, and flat lines to cover the water column effectively. Live bait fishing comes into play when you mark fish on the finder or when working structure like wrecks and reefs. The boat's equipped with quality tackle that can handle everything from scrappy blackfin tuna to monster blue marlin. Circle hooks are standard for most applications - they're better for the fish and increase your chances of a solid hookup. When a fish hits, the crew will coach you through the fight, helping you maximize your chances of bringing it to the boat. They know when to apply pressure and when to let the fish run, crucial knowledge that separates successful offshore trips from long days of broken hearts.
Blackfin tuna are some of the most reliable fighters you'll encounter on this trip. These smaller cousins of the giant bluefin rarely exceed 40 pounds, but they make up for size with pure attitude. They school up around structure and bait concentrations, often feeding aggressively in the early morning and late afternoon. What makes blackfin special is their accessibility - they're around most of the year in South Florida waters, with peak action typically from fall through spring. Once hooked, they make blistering runs and fight way above their weight class. Atlantic sailfish are the poster fish for Florida Keys offshore fishing, and for good reason. These acrobatic billfish put on an aerial show that'll have you scrambling for your camera between fighting the fish. Peak sailfish season runs from December through April, when cooler water temperatures bring them closer to shore. A typical Keys sailfish runs 6-8 feet long and 40-60 pounds, perfect size for exciting fights on appropriate tackle. Blue marlin represent the holy grail of offshore fishing here. These ocean giants can exceed 500 pounds and provide the fight of a lifetime. Summer months offer the best marlin opportunities, particularly around the full moon periods when baitfish are most active. Even a smaller marlin of 150-200 pounds will test your endurance and skill like no other fish in these waters. Greater amberjack are the bulldogs of the offshore world. These reef-dwelling bruisers use their broad shoulders and powerful tails to wage war in the deep. They're particularly abundant around wrecks and rocky bottom in 100-300 feet of water. Spring and fall provide peak amberjack action, with fish commonly ranging from 30-80 pounds. Wahoo are pure speed demons, capable of reaching 60 mph and making runs that'll empty your reel in seconds. These torpedo-shaped predators patrol the deep blue water, often hitting trolled baits at full speed. Their razor-sharp teeth and incredible acceleration make them one of the most challenging fish to hook solidly, but when everything comes together, you're in for the ride of your life.
This is exactly the kind of fishing trip that creates lifelong memories and converts casual anglers into offshore addicts.

Istiophorus AlbicansSailfish average around 7.5 feet and 50 pounds, with that signature sail-like dorsal fin they flash when hunting. They cruise surface waters from 30-65 feet but will dive deeper chasing baitfish. Winter months in the Keys are prime time - we're right in the famous "Sailfish Alley" that runs from Miami to Fort Pierce. These fish change colors when excited, flashing blues and blacks while they hunt in groups. What makes them special is the fight - they'll leap, dive, and put on an aerial show that's hard to match. They're built for speed, hitting up to 34 mph. Here's the key: when trolling, let your boat run slow so the leader swims naturally. When one takes the bait, stay patient - let them run first before you start working them back.
Thunnus AtlanticusThe smallest of the tuna family, blackfins typically run 20-40 pounds and rarely exceed 46 pounds. They're schooling fish with dark backs, silvery bellies, and distinctive yellow stripes that fade quickly after being caught. Around Islamorada, we find them in warm waters over 68°F, usually near the continental shelf. Fall through spring offers the best action in the Keys. These fish are absolute fighters - they'll test your endurance with powerful runs despite their smaller size. The meat is fantastic, darker and richer than other tunas. My tip: scale down to #30 fluorocarbon leaders and 5/0 circle hooks since they're sharp-eyed. Use live pilchards for chum to draw them close, then switch to vertical jigging or chunking once you locate the school.
Makaira NigricansThe giants of the billfish world - females can reach over 1,000 pounds (we call those "granders") while males rarely exceed 350. These cobalt-blue beauties with their spear-like bills roam the deep waters along the Gulf Stream. Here in the Keys, we see them year-round, but summer months bring the best chances. What sets blue marlin apart is their raw power and acrobatics - they'll sound deep then rocket to the surface in spectacular jumps. The fight can last hours on a big fish. They prefer warm water and follow baitfish like tuna and mackerel. While the meat has high mercury levels, it's all about the experience with these apex predators. Pro tip: use industrial-grade tackle and be ready for a long battle. These fish will test every piece of equipment you've got, so don't go light.
Seriola dumeriliAmberjack are bruiser reef fish that'll average 30-40 pounds but can push 80-plus. They're built like torpedoes with that distinctive amber stripe running down their bluish-grey sides. You'll find them around wrecks, reefs, and structure from 60-200 feet deep. Spring through fall offers the most consistent action, especially April and May during their spawn. These fish are pure muscle - they'll drag you straight down to the structure and test your drag system. The meat is excellent when prepared right, though larger fish can carry ciguatera. What guests love is the immediate power - no long runs, just straight-down bulldogging that'll burn your arms. My advice: use heavy tackle with at least 50-pound line and don't give them an inch early in the fight. Live bait works best, but they're not picky - metal jigs are deadly too.
Acanthocybium SolandriWahoo are speed demons that'll stretch 3-5 feet and hit 40-60 pounds, with razor-sharp teeth in a beak-like mouth. They cruise open water from the surface to about 65 feet, often around floating debris or structure. Around here, July through November gives you the best shot at hooking one. What makes wahoo special is their blistering speed - up to 60 mph - and those smoking runs that'll melt your reel. The meat is premium white fish, mild and flaky like a cross between tuna and mahi. They're solitary hunters that'll appear out of nowhere and disappear just as fast. The key is high-speed trolling at 12-15 knots with wire leaders since they'll cut through mono in a heartbeat. Use diving lures or skirted ballyhoo, and when one hits, hold on tight - that first run will test your drag and your nerves.
