Chase Tuna and Swordfish in Open Water

Book an offshore fishing trip on the 37 Freeman with Bentrod Fishing Charters serving all of the U.S.

When you fish the open waters beyond Grand Isle, you want a boat that holds steady in big swells and covers distance fast. The 37 Freeman catamaran is designed for that, powered by four Honda 300 engines installed in 2025 and built on a 2016 hull that handles rough Gulf conditions without pounding passengers. You target deep water species such as Snapper, Tuna, Swordfish, Grouper, Mahi-Mahi, and Cobia, and you reach structure or temperature breaks in Grand Isle waters faster than you would on a mono hull.

Bentrod Fishing Charters offers this offshore charter in three durations: a half day for 1800 dollars, a full day for 2400 dollars plus fuel, or a 24 hour trip for 4800 dollars plus fuel. Fuel is variable and depends on how far you run to find fish. The catamaran design reduces roll, making the ride more comfortable when you spend hours waiting on a bite or working bait in rolling seas. You get the stability of a platform that does not lean hard into turns or pitch bow-first into chop.

Why Catamaran Boats Work Better Offshore

You board the 37 Freeman at the dock in Grand Isle and motor out through the inlets, usually running to depths of 80 feet or more depending on what species you are after. The four Honda 300 engines move the boat at speeds that put you on fish faster and give you more time with lines in the water. The twin hull design keeps the ride smoother when you cross chop or wind waves, and the wide beam gives you room to move around rods, coolers, and tackle without stepping on another angler.

When you hook a Yellowfin or Blackfin Tuna, you fight it standing on a deck that does not sway as hard side to side. The boat holds position better when you drift bait or troll lures over wrecks and ledges. After the trip, your catch is cleaned and iced, and you leave the dock with fillets ready for the cooler.

All rods, reels, tackle, and bait are included in the charter price. You bring food, drinks, sunscreen, and any personal items you need for the time offshore. If weather conditions become unsafe, the captain reschedules your trip or discusses alternative dates. The catamaran hull does not solve every rough day, but it does reduce how much motion you feel compared to a V-hull of the same length.

Questions We Hear from First-Time Offshore Anglers

Most people ask about fuel costs, what to bring, and what species run best in a given month before they book a trip out of Grand Isle.

What does fuel cost on top of the charter price?

Fuel depends on how far offshore you run and what species you target. On average, expect around $1,000 for a full day, though longer runs to deep structure or overnight trips cost more.

How many people can fish on the 37 Freeman?
The boat comfortably handles up to six anglers. More than that makes it difficult to manage multiple hooked fish or move around the deck safely.
What time do offshore trips usually leave the dock?
Most half day trips leave around sunrise, and full day trips often leave earlier to reach deeper water by first light. You confirm the exact time with the captain based on tides and target species.
What should I bring for a full day offshore?
Bring enough food and water for the hours on the boat, sunscreen, a hat, polarized sunglasses, and any motion sickness medication you normally use. The boat has storage for coolers and personal bags.
When is the best time to catch Tuna near Grand Isle?
Yellowfin and Blackfin Tuna run strongest from late spring through fall, especially when water temperatures rise and bait schools move offshore. Winter trips still produce fish, but the bite slows and weather limits safe days.

Bentrod Fishing Charters runs the 37 Freeman year-round out of Grand Isle, adjusting target species and fishing zones based on water temperature and seasonal patterns. Get in touch to book your offshore trip and lock in your preferred date before the calendar fills.
