Atlantic Gulf Fishing Charters
Fish deep waters off Marathon, Florida with Atlantic Gulf Fishing Charters. Target swordfish, tilefish, and snowy grouper on a 40-foot Hatteras equipped with electric reels for a comfortable, trophy-worthy adventure.
Atlantic Gulf Fishing Charters in Marathon, Florida operates a fleet equipped for every level of angler. The company runs family-focused outings and full offshore adventures aboard well-appointed vessels including a 30-foot Boca Grande center console and a luxurious 40-foot Hatteras. Trip options range from three-hour family trips up to 10-hour extreme big game excursions, with intermediate half-day, three-quarter-day, and full-day departures.
Experienced captains and seasoned crew lead each charter, teaching fishing skills on family trips and providing expert sportfishing techniques on offshore trips. Anglers can target tarpon, mahi-mahi, snapper, sailfish, tuna, wahoo, and other game fish depending on the chosen trip. The Marathon Humps Express ventures roughly 25 miles offshore to pursue trophy tuna, mahi-mahi, wahoo, and billfish, while deep dropping trips fish depths from about 300 to 2,500 feet for swordfish, tilefish, and snowy grouper using electric reels.
Family trips on both 30’ Boca Grande and 40’ Hatteras provide light tackle action ideal for beginners and children, while larger Hatteras charters offer comfort and top-tier gear for anglers chasing trophy catches. Flats fishing and lobster hunting options deliver a quieter, nearshore experience in crystal-clear waters of the Keys.
