For those true fishing enthusiasts, booking a full day fishing charter is a great option as you can go further out to 12-mile banks where Wahoo, Tuna, Mahi Mahi and Marlin are famously in abundance. Our charter boats are fully stocked with all the gear and equipment you’ll need, just ask, and we’ll get the beers for you too!

Mahi Mahi (Corryphaena Hippurus)

Also known as Dorado, Dolphin or dolphin-fish; these 3 to 25 pounder flat fish are quick and lithe, sometimes taking off out of the water when hooked. They are fast breeders and tend to hunt in pairs with schools usually lurking under any form of underwater debris.

Yellow Fin Tuna (Thunnus Albercares)

Also referred to as the Allison Tuna or Backache, the yellow fin is a most flamboyant fish typically weighing anywhere from 30 to 70 pounds. Available abundantly in the tropics, they are hardy when snared and will test your fishing skills to the limit. Tuna makes a great meal and have both commercial and sport value. Yellow fins can grow up to 8 pounds in a year and can grow to be massive weighing over 140 pounds in four years.

Black Fin Tuna (Thunus Atlantica)

The smallest of the tuna species, Black Fins weigh up to 15 pounds and are around 25 inches in length. They do not live longer than 5 years. These tropical fish are abundant on the reef and offshore the Caymans. Here there are plenty of shrimp and crab to feed on, they also hunt surface and deep water squid.

Great Barracuda (sphyreana barracuda)

The common barracuda or simply ‘Cuda’ can reach up to 6 feet long and is prolific in the waters over the Cayman reef. A notorious bait thief, the barracuda is not afraid to take bait even when the rest are wary, making it one of the most readily available on a Cayman Islands deep sea fishing expedition.

Blue Marlin (Makaira Nigricans)

The Blue Marlin is the superstar of game fish; made internationally famous by Hemingway and having lived up to that fame. It’s appearance is vivacious and speaks of speed and strength; putting on awe inspiring displays with jumps and dives when baited.

Wahoo (Acanthocibium Solandri)

The Wahoo is prized as a gourmet game fish because of its high quality meat and fast speed. Caught by trawling, they are found in either solitary or in schools of a few or a couple of hundred. Due to its availability close to shore, the Wahoo is a favourite of many sport fishermen who prefer their light to medium tackle.

King Mackerel (Scomberomorus Cavalla)

The King Mackerel is migratory. They are a medium sized catch and are typically 30 pounds but have been found to exceed 90 pounds. Typically, King Mackerel occurr in depths of 40 to 150 feet though larger ones will venture closer to shore. The mackerel is a carnivore preying on squid, jacks, cutlass fish and blue runners.

Fishing Seasons in Grand Cayman

Deep Sea Fishing in the Cayman Islands

In Grand Cayman, you can enjoy deep sea fishing all year round due to the consistently warm weather and waters.

January is the month to battle Wahoo offshore; they are still young and agile so get ready for a chase. By February however the Wahoo have become offshore monsters and the Mahi Mahi are beginning to tug at the bait. In March the Wahoo offshore have mastered the game with Mahi Mahi no longer juveniles. There are also Great Barracuda with sightings of Sailfish and Sword Fish in true Caribbean colours.

April brings more Mahi Mahi while May is Nassau Grouper season. June is by far the biggest fishing month in the Cayman Islands with Blue and White Marlin, Tuna and Mahi Mahi caught abundantly. The blue waters are overrun with Tarpon and Bonefish by the time July rolls in. Yellow Fin Tuna join the Mahi Mahi with the Tarpon, Bonefish, Permit, Pompano, Snapper Grouper, Triggerfish and many more.

In August, Marlin start becoming scarce but the Yellow and Black Fin Tuna open up. Mahi Mahi are the main deep sea game fish with a scattering of bonefish in the wades. By September, Black Fin and Yellow Fin Tuna, Skipjack, Mackerel and Barracuda are found in the richer fields which continue in October where there is a very decent number fish for deep sea fishing in the Cayman Islands.

In November, the first Wahoo of the new season start to show up and offshore Skipjacks are plenty. December is usually cold in temperate regions but the Cayman Islands have a variety of big fish, warm seas and soft sands.

Captain Benjie and crew, Shirley and Alex, were knowledgeable and went above and beyond to make sure our trip was everything we could have hoped for. The boat was comfortable, the snorkeling was beautiful and the visit to stingray city was superb. Definitely do the bioluminescent bay experience too…amazing! We had such a good time with them, we chartered the next day to try some fishing.

Many thanks for the great experiences and we hope to see you again!read more

We swam, waltzed, and kissed a stingray, played with all the fish and starfish, and caught a few tuna and a barracuda! We even saw a sunken ship! It is DEFINITELY a must see.

We had an amazing experience with Captain Benji, Slim and Shirley. We were able to do some snorkeling, pet a stingray and then went deep sea fishing. I cannot recommend this charter enough. The booking process was smooth and Kristie was always quick to answer any questions I had. We will definitely use Crystal Charters again. To top off the whole trip, we caught a wahoo and now get to have our fish for dinner tomorrow. How cool is that?!?read more

We did small group charter with our family and some friends to see Sting Ray City, Starfish Point, and some snorkeling. The trip was amazing and did not disappoint. Cass and Alex were friendly, knowledgeable, and able to show us and tell us all about the local area and fish.The highlight for me was their willingness to work with our kids and help them get comfortable with the interaction with the sting ray, the fish, and the star fish. I went in with a kid who was a bit scared, and I didn’t know how the snorkeling would go. Cass worked with her to make her comfortable in the water and around the sea life, and in the end, it was the highlight of her more
