Islamorada Six-Hour Offshore: Mahi, Tuna and Wahoo at the Humps

Deep Sea Three-Quarter Day is a six-hour offshore fishing charter that launches from Three Waters Resort & Marina in Islamorada, Florida. Slip out past the shallow reef edge into deeper water where the Islamorada humps—submerged limestone and coral pinnacles—hold concentrations of mahi, tuna and wahoo. Onboard a 55-foot sportfishing yacht with a shaded deck, air-conditioned cabin and a real head, this trip blends serious fishing with comfort and space for up to six guests.

The humps are classic structure: hard bottom and coral rubble that attracts bait, weeds and the birds that mark feeding fish. A professional captain and a mate run the spread and work the deck while you cast and battle, using live bait and rigging supplied by the crew. The fishing moves with tides and birds rather than a strict schedule, so the captain stays in productive zones to stack chances for fast, action-packed fishing across the six hours.

What makes this outing special for Islamorada is the combination of distance and platform. Two extra hours compared with a half day buys access to far humps, where larger pelagics roam—fish that push serious fights and bring back bragging rights. The yacht’s amenities mean you can cool off between sets, store catches on ice, and rinse off in comfort. The mate cleans and bags your fish at the dock, turning a hard day of angling into a ready-to-cook haul.

This is practical, salt-tested sportfishing: expect bird work, weed lines, trolling, and short drifts over structure. Key species include mahi (otherwise known as dolphin fish), yellowfin and blackfin tuna, and wahoo—each offering different tactics and adrenaline. You may also pass sea turtles, dolphins, and pelicans on the run; the offshore reef and humps are biologically rich.

Trips depart from Three Waters Resort & Marina, 84001 Overseas Hwy, Islamorada at 7 am and return around 1 pm. The trip rate covers boat and crew, fishing gear, live bait, licenses, ice and bottled water; catered meals and charcuterie are available by request. Tipping the crew is customary, 15–25% for good service. There is no explicit age minimum listed; group size is up to six guests.

Conservation-wise, local captains often practice selective anglers’ ethics: keep only what you need, use circle hooks where appropriate, and never anchor on coral. For photographers and anglers alike, the humps produce clear, punchy blue water and fast surface action—the moment a hooked mahi boils at the transom is as cinematic as it gets. Whether you’re chasing a first offshore bite or aiming for dinner, this six-hour run to the humps delivers focused fishing, real chances at big pelagics, and the easy comforts of a full-service sportfishing yacht. Book early; summer slots and weekend dates fill quickly.
