Deep Sea Fishing Bahamas: Target Marlin, Tuna & Wahoo in the Open Ocean

The Gulf Stream runs so close to Bimini’s western shore that the bottom drops from shallow flats to several hundred feet within a few boat lengths — local captains call this edge “the wall.” It was here, in the mid-1930s, that Ernest Hemingway fished the same waters now worked by charter boats out of Alice Town, and a 500-pound Atlantic blue marlin caught off Bimini is widely credited as the inspiration for The Old Man and the Sea. That concentration of big-game species so close to port isn’t unique to Bimini; across the Bahamas, the combination of the Gulf Stream, deep ocean trenches, and relatively light fishing pressure creates conditions that consistently deliver blue marlin, yellowfin and blackfin tuna, and wahoo within reach of a half-day charter.

This article is written for the angler — whether you’ve run offshore before or this is your first time rigging a ballyhoo — who wants to know which Bahamian islands put you in the best position to hook these three target species, when to go, and what the trip will actually cost and require. The focus stays on marlin, tuna, and wahoo across six of the most productive fishing grounds in the archipelago, with practical details pulled from local charter operators, marina rates, and seasonal data.

The table below lays out five key fishing destinations across the Bahamas, the species you can expect to find at each, the best season to book, and the primary technique you’ll use on the water. Each row draws from the same charter and catch data detailed in the sections that follow.

Bimini: The Gulf Stream Highway

Bimini sits roughly 50 miles east of Miami, and the Gulf Stream brushes its western shore so closely that the 100-fathom curve lies just two miles offshore. Local captains call the edge where the Great Bahama Bank drops into the Stream “the wall,” and it functions as a highway for pelagic species. Trolling for billfish begins within 15 minutes of leaving the dock — you can spend a morning on the flats chasing bonefish and be on the troll for marlin by early afternoon.

Blue marlin peak here from May through July, with most fish running 150 to 400 pounds; fish over 500 pounds show every season. Yellowfin tuna stack up along the same edge from March through July, and wahoo take over from November through March, when high-speed trolling at 12 to 16 knots around the full moon produces multiple hookups. The IGFA all-tackle bonefish world record (16 pounds 3 ounces) was set on Bimini’s inside flats in 2008, a reminder that the island offers more than just offshore action.

Charter pricing on Bimini is per boat, not per person, which brings the per-angler cost down sharply when you split with a group. As of 2026 rates published by Bimini Big Game Club Marina and Brown’s Marina, a half-day offshore trip targeting mahi, tuna, and wahoo runs roughly $600 to $900, while a full-day deep-sea charter for marlin and big tuna ranges from $1,200 to $2,000. Most charters include tackle, bait, and fishing licenses. The Balearia Caribbean Jet Express ferry from Fort Lauderdale reaches North Bimini in about two to two and a half hours and accepts fishing rods as standard luggage.

Abaco Islands and Walker’s Cay: Tournament Territory

The Abaco chain is one of the most versatile fishing regions in the Bahamas, with shallow flats on the lee side and deep Atlantic water on the windward. Inshore, bonefish work the turtle-grass beds around Green Turtle Cay and Treasure Cay; offshore, the canyons and reef edges produce blue marlin, white marlin, sailfish, yellowfin tuna, and mahi mahi. The variety has made the Abacos home to several major billfish tournaments, including the Custom Shootout and the Sea Spray Billfish Tournament on Elbow Cay.

Walker’s Cay, at the northern end of the chain, is a legendary name in big-game fishing. Its proximity to the edge of the Little Bahama Bank puts boats within reach of deep water quickly, and the island’s marina is fully operational again after a lengthy hiatus — though as of early 2026, Walker’s Cay still lacks accommodations onshore, so most anglers stay aboard in the marina or base out of Marsh Harbour. The Walker’s Cay Invitational in May draws serious competitors, and the surrounding waters hold blue marlin, white marlin, sailfish, and yellowfin tuna with less fishing pressure than more accessible ports.

Further south, the area known as the Pocket, off central Abaco, concentrates wahoo and billfish along a hidden underwater structure. Local charter captains know the seasonal patterns here, and multiple marinas — Boat Harbour, Sea Spray Resort, and Hopetown Inn and Marina — offer berthing and fuel. Treasure Cay, on Great Abaco’s northeastern coast, combines a relaxed atmosphere with consistent offshore action on marlin, tuna, and mahi mahi, and its marina is a comfortable base for multi-day trips.

Chub Cay and the Berry Islands: Grand Slam Grounds

The Berry Islands are a remote chain of more than 30 islands and over 100 small cays that sit on the edge of deep offshore drop-offs in the central Bahamas. Because the seafloor drops quickly into deep blue channels, prime fishing grounds lie just a few miles from shore. Chub Cay, at the southern end of the chain, has a reputation for Grand Slam opportunities — blue marlin, white marlin, and sailfish in a single trip — and its high-end marina sits beside deep ocean channels that attract large pelagic fish year-round.

Strong currents and nutrient-rich water push through the cuts between islands, creating feeding zones for mahi mahi, wahoo, yellowfin tuna, and marlin depending on the season. Great Harbour Cay, the main inhabited island in the Berry chain, serves as a popular base, with its marina serving as the main departure point for offshore trolling routes north and east of the island. The region is less crowded than Bimini or Nassau, and the rapid drop-offs mean you spend less time running and more time fishing.

One note for 2026: Chub Cay has converted to a private members-only island resort. The Chub Cay Open and Classic billfish tournaments were open to the public in 2025, but the policy for the 2026 season was not yet confirmed at the time of this writing. If you’re not a member, check directly with the marina about access before booking a trip there.

Tongue of the Ocean: The Deep Trench off Andros

The Tongue of the Ocean (often called TOTO) is an underwater canyon that reaches 6,000 feet deep between Andros Island and Nassau. The unique upwelling along this trench concentrates plankton and baitfish, which in turn draws pelagic predators close to shore. On the east side of Andros, the bottom drops directly into TOTO, putting blue marlin grounds just over a mile from land. Many of the Bahamas’ fishing records — particularly for blue marlin — have been set in this stretch of water.

Andros itself is the largest island in the Bahamas, with vast flats and blue holes on the west side and deep offshore water on the east. Its remote nature means less fishing pressure and highly productive waters. Besides blue marlin, the Tongue of the Ocean holds yellowfin and blackfin tuna, wahoo, and mahi mahi, and the area known as the Pocket (off the northern end of the trench) offers some of the most productive marlin fishing in the Atlantic, according to charter operators working out of Nassau and Andros.

Getting to Andros requires a flight from Nassau or a ferry from the capital, so it involves more logistics than Bimini or Grand Bahama. But for the angler who wants to fish a genuine oceanic trench without competing with a dozen other boats, the effort pays off. Most charters here operate out of small settlements on the east coast, and captains know the localized current patterns that push bait against the wall of the trench.

Eleuthera and Cat Island: Less Pressure, Consistent Action

Eleuthera’s long, narrow shape and proximity to deep ocean trenches on both the Atlantic and Exuma Sound sides make it a productive offshore fishing destination with relatively light charter pressure. The nearby Tongue of the Ocean brings nutrient-rich currents along the western side, and the Atlantic drop-offs on the east hold mahi mahi, wahoo, and yellowfin tuna most of the year. Primary targets include sailfish, blue marlin, and wahoo, with the best wahoo action running from November through March.

Cat Island, further south, offers pristine, less-pressured waters filled with marine life. Offshore reefs hold grouper and snapper, while deeper areas provide opportunities for sailfish and wahoo. The island’s eastern edge sees the same “blue marlin water” that ROFFS (a oceanographic forecasting service) tracks via satellite — darker, warmer water with a distinct chlorophyll signature that marlin and other pelagics associate with. In mid-March 2026, that water was sitting at roughly 77.5°F east of Cat Island, very close to the 20-year mean, suggesting a normal start to the season.

Both Eleuthera and Cat Island are less developed than Bimini or Nassau. You’ll find fewer charter boats and simpler accommodations, but the trade-off is water that sees a fraction of the traffic. If you’re comfortable arranging a trip through a local guide rather than a large marina, these islands reward with consistent action and the chance to fish without crowds.

With the destinations mapped out, the next question is how to turn that knowledge into a booked trip — what the seasons actually mean for your calendar, what a charter will cost, and what regulations you need to know before you cast.

Seasons, Pricing, and Regulations — What You Need Before You Go

The Bahamas offers productive deep-sea fishing year-round, but each species follows a predictable calendar. Blue marlin peak from April through October, with the hottest action May through July across most islands. Wahoo are a winter specialty: November through March, especially around the full moon, produces the most consistent high-speed trolling. Yellowfin and blackfin tuna run strongest from late spring through early fall, and mahi mahi are most abundant from March through June. For the best overall variety — marlin, tuna, and wahoo all in season — plan for May or June, when the spring and summer windows overlap.

Charter pricing across the Bahamas follows a similar pattern regardless of island, though exact figures vary by location and season. Based on rates published by Bimini Big Game Club Marina, Brown’s Marina, and Cat Cay-area operators for the 2026 season, you can expect the following ranges per boat (not per person):

Most charters include tackle, bait, and fishing licenses in the quoted price, but confirm this when you book. Tipping the crew 15 to 20 percent for good service is standard. Booking directly with a captain rather than through a hotel can save 20 to 30 percent, and bringing your own food and drinks keeps the day simpler.

Bahamian law requires a sport fishing permit for any non-commercial fishing in Bahamian waters. Most licensed charter captains include the permit in the trip price. If you’re running your own boat, you can buy a permit online through the Bahamas Department of Marine Resources or in person at a local marina. Permits are valid for 30 days. Foreign-flagged vessels 50 feet and larger must keep an automatic identification system active at all times while in Bahamian waters.

For US citizens traveling by sea to Bimini on the Balearia ferry, a valid US passport book or passport card is required — birth certificates and photo ID are no longer accepted by the carrier. All visitors must also complete the Bahamas Click2Clear travel card before arrival. Atlantic hurricane season runs June 1 through November 30, with peak activity in August and September; trips booked during this window should include travel insurance, as ferries and charters can be cancelled with little notice during named storms.

Before You Go — Deep Sea Fishing in the Bahamas

What’s the best island for a first-time deep sea fishing trip?

New Providence (Nassau) and Bimini are the most accessible options. Nassau offers a wide range of experienced charters and modern boats with quick access to offshore grounds holding mahi mahi, tuna, and marlin. Bimini puts you on the Gulf Stream wall within 15 minutes of leaving the dock, and the ferry from Fort Lauderdale makes it easy to reach without a flight.

Do I need my own fishing license, or does the charter cover it?

Most licensed charter captains include the required Bahamas sport fishing permit in the trip price. Confirm this when you book. If you’re fishing from a private boat, you need to purchase a permit online through the Bahamas Department of Marine Resources or in person at a marina. Permits are valid for 30 days.

What’s the one piece of gear I should bring that most people forget?

Extra wire leader. Wahoo cut through monofilament on the first strike, and having a few pre-rigged wire leaders can mean the difference between landing a 60-pound fish and watching it swim off with your lure. A hard rod tube also helps if you’re bringing your own rods on the Balearia ferry.

Is deep sea fishing in the Bahamas safe during hurricane season?

Fishing can be excellent in settled weather during August and September, but direct hits on specific islands are statistically uncommon. The real risk is last-minute cancellations: ferries and charters may cancel with little notice during named storms. Buy travel insurance for any trip booked between June 1 and November 30.

How far offshore do you actually go?

It depends on the island. Off Bimini, the Gulf Stream wall is two miles offshore — a 15-minute run. Off Andros’s east side, the Tongue of the Ocean drops to 6,000 feet just over a mile from land. In the Berry Islands, deep water begins within a few miles of the cays. Most full-day trips run 8 to 15 miles offshore; half-day trips stay closer to the reef edges and current breaks.

Closed Loop

The same Gulf Stream current that brought Hemingway to Bimini in the 1930s still pushes baitfish against the wall every tide, and the same 6,000-foot trench off Andros still concentrates pelagic predators within sight of land. What’s different now is how accessible these grounds have become — a ferry from Fort Lauderdale, a short flight from Nassau, and a morning on the water can put you in range of blue marlin, yellowfin tuna, and wahoo on the same trip. The Bahamas’ deep-sea fishing isn’t a relic of the sport’s golden age; it’s the reason the sport has a golden age here at all.
