The Bahamas have long held a special place in the hearts of shark enthusiasts. Tiger Beach, Bimini, the Exumas. These names carry weight. And now there is a new way to explore them. The Blue Marlin liveaboard brings together a brand-new vessel, deep operator experience, and access to the finest shark diving on the planet.
The Blue Marlin was launched in 2025. At 40 metres long and 9 metres wide, this steel-hulled vessel was built from the keel up with divers in mind. The dive deck is spacious. Gear storage is generous. There are dedicated rinse stations and a photo-video facility for those who like to document their encounters. What sets the Blue Marlin liveaboard apart is its safety certification. It meets international passenger ship safety standards. That puts it in a small class of liveaboards worldwide. Peace of mind comes standard.
Accommodation on the Blue Marlin handles up to 26 guests across 14 cabins. Each cabin has an ensuite bathroom, individual air conditioning, and ocean views. Choose from 2 single cabins, 10 twins, or 2 king-size cabins. The living areas include a panoramic lounge, a bright dining space, and a sun deck with an open-air bar. Between dives, you can book a massage or join a yoga session. The 17 crew members include 5 professional dive guides. They know the Bahamas, they know the sharks, and they know how to keep everyone safe and comfortable.
The cruise routes read like a highlight reel of Bahamian diving. Bimini, Tiger Beach, Grand Bahama, Nassau, Andros, Cat Island, the Exumas. Each stop offers something different. Tiger Beach delivers close encounters with tiger sharks in crystal clear water. Bimini is the place for great hammerheads. Oceanic whitetips appear on offshore sites. Beyond the sharks, you will find vibrant coral reefs, mysterious blue holes, and historic wrecks. The Blue Marlin takes you to the best of it, without the crowds.
For technical divers and rebreather users, the Blue Marlin is a rare find. The boat partners with KISS Rebreathers and DiveTalk to provide instruction and access to the latest DiveTalk GO! rebreather systems. Nitrox is available. Whether you dive open circuit or closed, you are covered.
Behind the Blue Marlin liveaboard stands Seafari, a company founded in 1992 with decades of liveaboard experience in Egypt, the Maldives, and now the Bahamas. That history matters. It means the operation runs smoothly. The crew knows what divers need. The food is good. The service is attentive. And the focus stays where it belongs: on the water. If you have dreamed of swimming with tiger sharks, great hammerheads, or oceanic whitetips in clear, warm Bahamian seas, this is your boat. The Blue Marlin is ready. So should you be.

Day 1
Freeport, Grand Bahama. That is where you find the Blue Marlin liveaboard. The crew takes your bags, shows you your cabin, and gathers everyone for the safety briefing. Then the engines rumble to life. The harbour falls away. Dinner comes with a view of the open ocean. Sleep comes easy. Tomorrow, you meet the tigers.
Core Days
The Blue Marlin anchors in the sand. You look over the side. Turquoise water. White bottom. Nothing special to see from the surface. Then you drop in. Tiger Beach needs little introduction. It is unlike any other dive site on the planet. Large female tiger sharks dominate the patch. Some pushing four metres. They cruise past with a slow, deliberate grace. Bull sharks join them. Lemon sharks, Caribbean reef sharks, Silky sharks, nurse sharks resting on the sand. All in the same stretch of shallow, crystal-clear water.
Safety protocols are strict and the dive briefings are thorough. You dive in small groups of up to 8, under expert supervision. The sharks come close but they are not aggressive. You kneel on the sand and watch them circle. A tiger shark passes within arm's reach. You see every spot on its side, every scar. Your heart pounds, then you settle. The sharks have done this thousands of times and you are a guest in their home.
Between shark dives, the Blue Marlin liveaboard moves to Mount Olympus. A giant coral pinnacle visible from satellite imagery. The peak starts at 18 metres and drops to over 450 metres. You swim through valleys where the walls rise on both sides. The scale is humbling. Big animals patrol the edge. Hammerheads pass by in the blue. Manta rays glide through. Dolphins occasionally join the dive. Even tiger sharks cruise the wall. Mount Olympus is not just a reef dive. It is a reminder of how large the ocean really is.
Mini Wall delivers a different energy. Healthy soft and hard corals cover the slope. Caribbean reef sharks and lemon sharks patrol the edge. Turtles feed on the sponges. Eagle rays glide past. On lucky days, a great hammerhead visits. You hover near the ledge and watch it cruise by. The macro life is good too - nudibranchs, shrimp, small reef fish hiding in the corals.
At the end of the trip, the crew fires up the BBQ on a secluded island. White sand. Warm sun. Cold drinks. Freshly grilled food.
Day 6
Wake to breakfast and coffee on the Blue Marlin in Freeport. A transfer takes you to the airport or your hotel after disembarkation. You leave with a camera full of tiger shark portraits, lemon shark videos, and the satisfaction of having spent a week in the company of apex predators.

Day 1
Board the Blue Marlin liveaboard in Freeport, Grand Bahama. The crew welcomes you aboard, shows you to your cabin, and runs through the safety briefing. Settle in as the vessel clears the harbour and begins the overnight run toward Bimini. Dinner is served on deck. You wake tomorrow in great hammerhead territory.
Core Days
The Blue Marlin anchors off South Bimini, and you waste no time. These western islands sit just 50 miles from Miami, but they feel a world away. From December through April, great hammerheads gather here in numbers seen almost nowhere else on Earth. You drop into shallow, crystal-clear water. The sharks appear out of the blue. Large females. Some over four metres. They cruise past at arm's length. Bull sharks join them. Nurse sharks rest on the sand. Tigers pass through. Your heart rate spikes. Then you settle into the rhythm. The sharks do this every day. You are a guest in their home.
Between shark encounters, Bimini's reefs hold their own. Victory Reef sits on the edge of the Gulf Stream. Current brings nutrients. The coral is healthy. Schools of snapper and barracuda patrol the walls. Tuna Alley delivers exactly what the name promises, fast-moving pelagics in clear water. Turtle Rocks lives up to its billing. Hawksbill and green turtles feed on the sponges. They let you get close. Hawksbill Reef adds soft corals, sea fans, and the occasional eagle ray gliding past.
Wreck enthusiasts get 2 very different experiences. The SS Sapona sits in just 3 metres of water. A concrete-hulled steamship from the early 1900s. A hurricane drove it onto the reef in 1926. Today, it is covered in marine life. Crabs, lobster, rays, and turtles. You can swim through the exposed ribs. History and marine biology in one shallow dive. The Bimini Barge sits deeper, close to 30 metres. An array of healthy coral covers the steel. Moray eels peer from holes. Parrotfish graze on the algae. Nurse sharks rest among the wreckage.
Then the Blue Marlin moves to Tiger Beach. Grand Bahama's most famous stretch of sand lives up to the reputation. Large female tiger sharks dominate the site. Some pushing 4 metres in length. Bull sharks, lemon sharks, Caribbean reef sharks, silkies, nurse sharks. All in the same patch of turquoise water. Briefings are thorough and safety protocols are strict. You dive in small groups under expert supervision. The sharks come close, very close. But they are only curious, not aggressive. You kneel on the sand and watch them circle.
Other than the sharks, Mount Olympus demands attention. A giant coral pinnacle visible from satellite imagery. The peak starts at 18 metres and drops to over 450 metres. Canyons of coral dwarf scuba divers. Hammerheads pass by, manta rays, dolphins, even tiger sharks cruising the wall. Mini Wall, also known as Shark Ledge, drops from 5 metres to 20 metres. Healthy soft and hard corals cover the ledge. Caribbean reef sharks and lemon sharks patrol the edge. Turtles feed on the sponges, eagle rays glide past. On lucky days, a great hammerhead visits.
Between dives, the crew fires up the BBQ on a secluded island. White sand, warm sun, cold drinks, freshly grilled food. You swap stories about the shark that got too close and the turtle that would not move. This is the surface interval you came for.
