Fullday offshore charter targets tuna, marlin, and mahimahiAccommodates up to six guests with professional fishing equipment includedSeasonal fishing focuses on reefs and deep water species
Miller Time Sportfishing knows what serious anglers want – a full-day offshore charter that puts you on the fish without the crowds. Our Islamorada deep sea fishing trips take you past the reef line into the blue water where the big pelagics roam. With just six anglers max, you'll get plenty of rod time and personalized attention from our crew. We're talking 8-10 hours on the water, covering serious ground to find where the fish are stacked up that day.
Your day starts early at the dock in Islamorada, where our crew will have the boat prepped and ready. We'll head out through the channels toward the deep water, usually running 8-15 miles offshore depending on conditions and what's biting. The Florida Keys location puts us right in the path of major migration routes, so you're fishing some of the most productive waters in the Atlantic. Our captain reads the water daily – checking temperature breaks, current lines, and bird activity to put you on the best bite. Summer months bring the pelagic action closer to shore, while winter fishing often keeps us working the reef edges and deeper structure. Either way, you're in for a workout.
We run a mix of techniques to maximize your shots at different species. Trolling spreads with ballyhoo, bonito strips, and artificial lures cover water fast when we're hunting mahi, wahoo, and tuna. When we mark fish or find floating structure, we'll switch to live bait fishing with goggle eyes, pilchards, or whatever bait is running thick. Bottom fishing comes into play around wrecks and ledges, especially during winter months when the grouper and snapper are holding deep. Our tackle ranges from 20-pound spinning gear for smaller pelagics up to 50-pound conventional setups for the big boys. All rods, reels, tackle, and bait are included – just bring your fishing license and be ready to fight some fish.
Blackfin tuna are the bread and butter of our summer trips, schooling up in 150-400 feet of water. These fish hit hard and fight dirty, averaging 15-25 pounds with some pushing 40. They're excellent table fare and put up a scrap that'll test your stamina. Blue marlin patrol the deeper water during summer months, and while they're never guaranteed, Islamorada sits in prime marlin territory. Most fish we see run 200-400 pounds, though bigger fish cruise through regularly. The fight is what legends are made of – long runs, aerial displays, and battles that can last over an hour.
Mahi mahi show up around any floating debris, weed lines, or current breaks from late spring through fall. These fish are aggressive feeders and spectacular fighters, jumping repeatedly when hooked. School fish run 5-15 pounds, but bull mahi can push 40-50 pounds and provide serious entertainment. Wahoo are speed demons that hit trolled baits like freight trains, often at boat speeds of 8-12 knots. They're built for speed with razor-sharp teeth, capable of 50+ mph runs that'll smoke your drag. Most wahoo here run 20-40 pounds, with the occasional 60-pounder showing up to make your day memorable.
Black grouper hold around the deeper ledges and wrecks, especially during cooler months. These fish are powerful bottom dwellers that'll try to cut you off in the rocks the second they feel the hook. They're prized for their excellent eating quality and the challenge of getting them up from 100+ feet of water. Most fish run 5-20 pounds, but the offshore structure can produce some real monsters over 50 pounds.
At $1,800 for up to six anglers, this full-day charter delivers serious value for groups looking to experience world-class offshore fishing. The Islamorada location puts you in the heart of Florida Keys fishing action, with short runs to productive water and year-round opportunities. Our experienced crew knows these waters inside and out, adjusting techniques and locations based on seasonal patterns and daily conditions. Whether you're after a freezer full of fish or that trophy shot for the wall, this trip gives you the time and territory to make it happen. Book early – the best fishing days fill up fast, especially during peak seasons when the bite is hot.
Mycteroperca BonaciBlack grouper are bottom dwellers that can reach 50+ pounds, though most run 10-25 pounds around our reefs and wrecks. These olive-colored bruisers with dark blotches are ambush predators that live in structure from 30-200 feet deep. Winter months are prime time when they move shallow, but we catch them year-round. What makes grouper fishing special is the sudden thump when they inhale your bait, followed by a bulldogging fight straight down to the rocks. The white, mild meat is absolutely delicious and highly prized. We use heavy tackle with 80-pound braid and stout rods since they'll try to cut you off in the coral. Live pinfish, grunts, or dead sardines work great. Critical tip: when you feel that bite, crank hard immediately - don't give them time to get back in the rocks or you'll lose them.
Thunnus AtlanticusBlackfin tuna are the smallest in the tuna family, typically running 15-30 pounds around Islamorada, but they pack a serious punch. These fish love our warm Gulf Stream waters and hang out in schools, making summer our prime time for targeting them. You'll find them in blue water from 100-600 feet, often mixed with skipjacks. What makes blackfins special is their incredible fight - they're built like torpedoes and will test your drag system hard. The meat is outstanding too, perfect for sushi or searing. They've got sharp eyes, so we scale down to lighter fluorocarbon leaders and smaller circle hooks. Pro tip: when you find one blackfin, there's usually a whole school nearby, so keep your lines in the water and work the area thoroughly.
Makaira NigricansBlue marlin are the ultimate offshore prize - these billfish can reach over 400 pounds and put on an aerial show you'll never forget. We target them in deep blue water beyond the reef, typically in 600+ feet during our summer season when the Gulf Stream pushes closer to shore. Females grow much larger than males, and when one hits your trolled ballyhoo, you know it instantly. The strike is explosive, followed by jumps and long runs that'll test your tackle and endurance. While the meat has high mercury levels, most anglers release these magnificent fish. We troll with 50-80 pound gear and wire leaders since their bills are like swords. Here's the key: when a marlin comes up behind your bait, resist the urge to speed up - let it eat and count to ten before setting the hook.
Coryphaena HippurusMahi mahi are summer favorites around floating debris and weed lines, typically running 15-40 pounds with gorgeous golden colors that flash like neon underwater. These fish are pure excitement - fast swimmers that jump repeatedly when hooked and travel in schools around any floating structure. We find them from May through September in our offshore waters, especially near sargassum patches. The meat is white, flaky, and some of the best eating you'll find, plus they're sustainable to keep. Bulls have that distinctive square head while cows are more rounded. They hit trolled ballyhoo, live bait, and artificials with aggression. Once you hook one, keep other lines in since they school up. Pro tip: when you see frigate birds working floating debris, get your baits in the water fast - mahi are probably feeding below.
Acanthocybium SolandriWahoo are speed demons that'll smoke your drag at 50+ mph, typically weighing 20-60 pounds in our waters around Islamorada. These torpedo-shaped fish have razor-sharp teeth and prefer deeper blue water along drop-offs and near structure. Peak season runs July through November when they move closer to shore. The fight is pure adrenaline - long screaming runs followed by powerful dives. The white, flaky meat is premium table fare, often compared to tuna but milder. We troll fast at 12-15 knots with wire leaders since they'll cut through anything else in a heartbeat. Look for them around oil rigs, seamounts, and temperature breaks. Secret weapon: use a planer to get your baits down 30-40 feet below the surface where wahoo often cruise, and always have your drag set properly before the strike.
