Offshore Fishing
Target shark, tuna, and mahi mahi in deep offshore watersSix-person capacity allows intimate group fishing experienceProfessional charter service operates from Groton, Connecticut waters
Picture yourself miles offshore in the deep Atlantic waters off Groton, Connecticut, where the continental shelf drops away and the real monsters live. This isn't your typical harbor fishing trip – we're talking about blue water action where yellowfin tuna cruise the depths, mahi mahi light up in electric colors, and thresher sharks patrol with their signature whip-like tails. Captain and crew at Angler Management Fishing Charters II know these waters like the back of their hands, and they're ready to put you on fish that'll test every ounce of your tackle and technique. With space for up to 6 anglers, this top-rated charter gives you the perfect mix of personalized attention and competitive camaraderie that makes offshore fishing so addictive.
Your day starts early – we're talking pre-dawn departure to maximize your time in the prime fishing zones. The boat heads out from Groton, cutting through Long Island Sound before hitting the open Atlantic where the real action begins. You'll be fishing in 100 to 300 feet of water, sometimes deeper, depending on where the fish are showing up on the electronics. The crew sets up a spread of trolling lines with different lures and baits, each designed to trigger strikes from specific species. Don't worry if you're new to offshore fishing – the captain will walk you through everything from setting the drag to fighting technique. The boat's equipped with quality Penn and Shimano reels spooled with heavy braid, plus all the terminal tackle you'll need. Just bring your enthusiasm and maybe some seasickness meds if you're prone to getting queasy in the swells.
Offshore fishing here is all about covering water and reading the signs. We're primarily trolling, which means running multiple lines at different depths and speeds to mimic injured baitfish. The spread typically includes cedar plugs, spoons, and ballyhoo rigs – each with its own purpose and target species. When the sonar marks bait schools or temperature breaks, that's when things get interesting. The captain might call for a direction change or speed adjustment to stay in the strike zone. Once a fish hits, it's game on – the crew will clear the other lines while you battle your catch. Circle hooks are the standard here, so when that rod tip goes down, just come tight and let the hook do its job. No hard hooksets needed, just steady pressure and smooth pumps to work the fish toward the boat.
Yellowfin tuna are the crown jewel of these offshore waters, and for good reason. These fish are pure muscle wrapped in silver, capable of blistering runs that'll have your reel screaming. Yellowfins in this area typically range from 30 to 80 pounds, with the occasional monster pushing triple digits. They're most active from late spring through fall when water temperatures hit that sweet spot above 68 degrees. What makes them so special is their fight – they'll sound deep, then make heart-stopping surface runs that can strip 200 yards of line in seconds. Plus, they're fantastic eating, with that deep red meat that's perfect for sushi or searing.
Mahi mahi bring the flash and athleticism that every angler dreams about. These fish are living rainbows, changing colors from brilliant gold to electric blue and green when they're fired up. They love floating debris and weed lines, where they ambush flying fish and other prey. Connecticut's mahi typically run 10 to 30 pounds, though bull dolphins can push 50-plus. What makes them customer favorites is their aerial display – they'll jump, tail-walk, and put on a show that'll have everyone on the boat grabbing their phones. They hit hard and fight dirty, but they're also some of the best eating fish in the ocean with sweet, flaky white meat.
Thresher sharks are the wildcards that can turn a good day into a legendary one. These prehistoric predators use their elongated tail fin like a whip to stun schools of baitfish, creating feeding frenzies that attract other species too. Connecticut threshers commonly reach 8 to 12 feet and 200-plus pounds, making them serious adversaries on heavy tackle. They're most active during summer months when baitfish concentrations peak around the offshore structure. Fighting a thresher is like being connected to a submarine with an attitude – they'll sound deep and use their size to test your endurance. The reward is an Instagram-worthy photo with one of the ocean's most unique apex predators before release.
This world-class offshore fishing experience gives you access to some of the Atlantic's best gamefish without the hassle of traveling to exotic destinations.

This 32-foot Downeast beauty from Judge Yachts is your ticket to serious offshore action in Groton's productive waters. With a powerful 330HP Cummins diesel pushing you through the swells, you'll reach the deep water fishing grounds where the big pelagics roam. The spacious cockpit gives you and up to 5 other anglers plenty of room to work the rods when you hook into those lightning-fast tuna or hard-fighting mahi. GPS navigation keeps you on the fish and safely back to port. Whether you're trolling for sharks in the canyons or casting to breaking fish on the surface, this classic New England design handles the open ocean with confidence. The comfortable interior provides a welcome break from the salt spray between fishing spots.
Coryphaena HippurusMahi are the rainbow warriors of offshore fishing - golden sides with electric blue and green that put on a light show when they come out of the water. Most run 15-30 pounds and about three feet, but the bulls can hit 50+. They love floating debris, weed lines, and current breaks in the top water column. Peak season here runs late spring through early fall when water warms up. These fish fight like crazy with lots of jumps and runs, plus they're fantastic eating with that mild, sweet white meat. We troll the edges and debris lines with ballyhoo or colorful lures, keeping them skipping on the surface since they love chasing flying fish. Here's the key: once you hook one, keep the boat moving - mahi travel in schools and you can often double or triple up.
Alopias VulpinusThresher sharks are something special with that tail as long as their body - they use it like a whip to stun baitfish at 50 mph. These blue-grey predators average around 16 feet and 500 pounds, cruising 40-50 miles offshore in 25-2000 feet of water. Best fishing runs late spring through fall when they follow the bait north. What makes them awesome is that explosive fight - they'll jump clear out of the water and run hard with those 30 mph bursts. We target them by trolling mackerel or sardines 25-50 feet down around bait schools, drifting 2-4 knots. Despite their size, they have small mouths, so use strong 8/0 hooks with heavy leaders. My trick: when you see them working bait balls, get ready for multiple shots - they sometimes hunt in small groups.
Thunnus AlbacaresYellowfin are the speed demons of our offshore waters, hitting 50 mph with that torpedo-shaped body. Most of what we catch runs 60 pounds, but they can push 400+ if you're lucky. Look for them in the top 100 feet of water column from late spring through fall when water temps climb. That bright yellow tail and fins make them unmistakable. These fish fight hard and taste even better - premium sashimi quality that rivals bluefin at half the price. We troll rigged ballyhoo and cedar plugs, but nothing beats the rush when one smashes a surface plug. Pro tip: when marking fish deep but nothing's biting on the troll, switch to jigging - sometimes they're feeding down there and won't come up for the spread.
