Fishing near Islamorada
Flats skiffs pole for bonefish, permit and tarpon in the backcountry, and offshore boats run to the reef and the Gulf Stream for sailfish, mahi and tuna. Kayakers paddle the mangrove creeks.
Boating around Islamorada
Whale Harbor and Snake Creek are the main channels between Florida Bay and the Atlantic, and marinas along US-1 host charter fleets. Florida Bay’s shallow basins and mangrove keys lie to the north, part of Everglades National Park. Alligator Reef, with its lighthouse, sits offshore.
Islamorada is made up of several keys, including Plantation Key, Windley Key, Upper Matecumbe and Lower Matecumbe. The town’s marinas are home to many of the Keys’ best-known fishing guides and charter captains.
Choosing the right battery
Bay boats and flats skiffs
Most bay boats on the Florida Bay backcountry run a 24V or 36V bow-mount trolling motor plus a separate cranking battery for the outboard. A 36V lithium bank, such as a single EPOCH 36V or Interstate 36V battery, replaces three Group 27 or 31 lead-acid batteries and drops well over 100 pounds from the stern, which helps a skiff float shallower. Keep the cranking battery separate so a long day on the trolling motor never leaves you unable to start.
Twin-engine and offshore boats
If you run twin or triple outboards, replace cranking batteries as a matched set. AGM batteries in Group 31 size are a dependable starting choice for big outboards, and many Islamorada owners add a lithium house battery so the electronics never touch starting power. Check your engine maker’s cranking amp requirement before you choose.
Kayaks and small boats
Small boats and jon boats around Islamorada often run a small trolling motor and a fish finder. A 12V 50Ah or 100Ah lithium battery saves weight and keeps the trolling motor strong all day.
Battery care for Islamorada boats
Poling skiffs benefit from light lithium batteries: less weight means floating in shallower water.
The Keys are hot, humid and salty all year, and a battery in a closed console can sit well above 100°F in summer. Sealed AGM or lithium batteries handle that better than flooded ones, and they won’t spill on a hard run across Hawk Channel. Rinse and coat terminals after every trip.
Hurricane prep is part of owning a boat in the Keys. Before a storm, charge everything fully and switch the batteries off, or pull small lithium batteries and store them indoors. A boat on a lift with a dead battery can’t run its bilge pump.
