Islamorada Mahi Mahi Charters

Offshore Hunting | The Humps | 8 Hours

What Is a Mahi Mahi Charter in Islamorada?

An Islamorada mahi mahi charter is a full-day offshore trip focused on trolling weed lines, current edges, birds, floating debris, and the Humps for dolphin fish. These trips are especially good in spring and summer and can turn chaotic fast when a school shows up behind the boat.

Offshore Mahi Mahi Hunting in the Florida Keys

Experience an unforgettable full-day Offshore Charter focused on Mahi-Mahi hunting. Our 8+ hour adventure begins with catching live bait at the reef before setting sail to "The Humps"—magnificent undersea mountains near Islamorada.

Throughout the journey, we carefully troll, keeping watch for diving birds and floating debris that signal the treasure hidden beneath the waves.

The "Schoolie" Chaos

Once we hook a Mahi, if the school follows it to the boat, we swiftly switch to spinning gear and live bait. It is pure exhilaration—hooking fish right next to the boat, filling the cooler, and using gaffs to land the big bulls.
