Where Grand Isle boaters launch and cruise
Barataria Bay lies behind the island, and Caminada Pass and Barataria Pass lead to the Gulf.
Grand Isle State Park, at the east end of the island, has a fishing pier and beach access, and the town’s marinas and launches serve charter captains and private boats heading into Barataria Bay or out to the Gulf. The Grand Isle International Tarpon Rodeo, one of the oldest fishing tournaments in the country, is held every summer. Offshore, oil and gas platforms draw red snapper, tuna and other species, and inshore anglers work the marshes for trout and reds. The island is low and exposed, and hurricanes have hit it hard many times, so boats are often moved inland when a storm threatens. Before a storm, charge batteries and switch them off.
Typical boats around Grand Isle
Speckled trout, redfish and offshore fishing.
Seasons and storage
Salt and heat call for sealed batteries.
Hurricane season runs from June through November. Before a storm, charge and disconnect batteries, and if you haul out, store small lithium batteries indoors.
The northern Gulf Coast has long, hot summers and mild winters, with salt air and humidity year round. Heat is the main battery killer, so keep batteries charged and ventilated. Sealed AGM or lithium batteries are a good fit for boats that live in the water or on lifts.
Recommended setups
Bay boats and flats skiffs
Most bay boats on Barataria Bay 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
Center consoles that run offshore from Grand Isle usually have one cranking battery per engine plus a house battery for electronics, pumps and lights. For cranking, a Group 27 or 31 AGM with high marine cranking amps is the common choice. A lithium dual-purpose battery like the EPOCH 172Ah can serve as a house battery and an emergency start, and it weighs a fraction of an equivalent AGM.
