Great time despite less-than-ideal weather conditions
We enjoyed the trip despite generally high winds that limited our diving to one side of Grand Cayman and kept us from the planned itinerary of diving sites off Little Cayman and Cayman Brac. Our captain, Sarah, did a fantastic job keeping us safe in the bad weather, and in selecting dive sites that had either low or no current. Iain and all the rest of the crew were excellent, and also kept us safe, well-fed, and happy under and above the water!

25 amazing dives, great crew, great food & a fun group
We had 25 amazing dives with so many marine life sightings, interesting wrecks and beautiful coral walls & swim throughs. The entire crew was friendly, helpful and despite weather conditions that kept us in a limited area, provided an excellent experience. The food and snacks were very good and nicely catered to our pescetarian diet. We also had a fun group of divers that made us feel like we were on a trip with a bunch of new friends.

Cayman Islands Liveaboard
We had a fabulous week aboard the Cayman Aggressor IV with Captain Josh & 2nd Captain Sarah & their fabulous crew Rodel, Mili, Chelsea, Braven & David! The liveaboard is in excellent condition…our room was great, we never felt crowded & had plenty of room on the dive deck as well as space to hang out and relax on the top deck between dives. Chef Chelsea was hard at work all week preparing amazing food and snacks and we had plenty of vegetarian options to choose from. We had beautiful weather and we were able to dive all 3 islands. We had such a fun group & met so many nice people traveling from all over & just had a really nice time together between diving, sharing meals and hanging out. Definitely enjoyed the warm showers on the dive deck and hot towels between dives and hot chocolate with Baileys after our night dives….oh, in the hot tub! Lots of ocean life on our dives and Barry the Barracuda like to hang out under the boat and mess with us on our night dives! Highly recommend! We can’t wait to book our next adventure!

Your Best Choice for a Liveaboard Trip
I have been on many liveaboards in my 1400 + dives. This is an exceptional crew and staff. The water visibility approached 100 feet on many dives and allowed for terrific photography. The wind was 20+ mph on many dives, but the bath robes provided a great deal of warmth after the dives. You don't need to pack a lot of sweats and jackets. The boat provides the towels and bath robes that will keep you warm. The food and beverages were absolutely the best! Steak and lobster on the Friday last dinner was epic!

The food was over the top great at every meal.. All the staff was welcoming and each shared in every activity from the captain to the cook.. The dive support was the best I have experienced on any liveaboard..

Aggressor lives up to it's great reputation.
Excellent liveaboard. We were able to hit all the best dive sites in Grand Cayman and Little Cayman. Special Thank You to Captain Sarah. She was truly amazing. Sarah put a lot of effort into finding us the best dive sites with best conditions. We went to a new location for almost every dive. We were very glad to have such knowledgeable, professional, passionate and caring captain. Great leadership. Great crew. They took very good care of us, and the food was excellent.

Nothing short of amazing.
Captain Sarah keeps us on the loop about the plans, the conditions, the crossings to and from Little Cayman and Cayman Brac and her and her team go the extra mile to make our week unforgettable. The sites are more interesting than we had expected, the marine life is surprising and the whole experience on the Aggressor is top notch. Extraordinary Captain, amazing crew and the chef Chelsea is doing miracles in this small galley. We loved it so much that we have already booked our next Agressor adventure!

The Best dive, eat, sleep and repeat trip ever.
The ship was perfect for a dive trip. The crew were simply the very best. many great friendships were made with other divers. Best way to describe is dive, eat, sleep, repeat. The food was excellent, the ship relaxing and the crew were outstanding in making sure we were safe and had the best time. This was my first liveaboard and it won't be the last with Agressor--I just hope the next one can live up to the standards created by Captain Josh and crew!!!

I loved so much about this liveaboard- it felt like summer camp for grown ups. The food was insane, and I loved the access to snacks and drinks throughout the day. The staff were all phenomenal, and even though part of their jobs was to be nice to us, it felt very genuine. The boat was well equipped for diving and my cabin was cozy (in the best way!). Five stars!

Great Dive trip
Just landed from a a great week on the Cayman aggressor. Many of the dives were amazing, several were excellent, a handful were good maybe one or two were average bit out of 25 dives we were pretty pleased. The crew and even the captain do ALL jobs. So you get half a dozen engaging dive masters. And any time a crew member sees you looking around they ask what they can do for you. The food was EXCELLENT, made diving on a full stomach tough, but we all cleaned out plates, it was too good not to. They rooms were on the smaller side but good value for the money. Check the time of year if diving in Cayman Brac & Little Cayman is important to you. Weather makes the crossing unlikely in some months.

Simply the Best – An Unforgettable Week on the Cayman Aggressor IV!
This was my first liveaboard experience and it absolutely blew my expectations out of the water—I’m already looking to book my next one! From the moment we stepped aboard, the crew made us feel like family. The yacht was spotless, well-maintained, and thoughtfully designed for comfort and convenience. Captain Billy and Sarah, Rodel, Daniel, Fabian, JC, and Chef Chelsea—this dream team went above and beyond every single day. Their professionalism, warmth, and humor created a welcoming, safe, and fun atmosphere. We had an incredible group of divers from around the world, and it was a joy to dive and swap stories with such an adventurous crew. The diving? Phenomenal. We explored vibrant reefs, wrecks, and got in several night dives. Coming back from those with Baileys hot chocolate was an added highlight! Speaking of chefs—Chef Chelsea is magic. Every single meal was a highlight, from breakfast to dessert. I genuinely don’t think she’s capable of making a bad dish. The food was fresh, flavorful, and satisfying with a full day of diving. Though I came prepared with all the extras, the Cayman Aggressor IV had everything and more. I am beyond grateful for such a memorable first liveaboard—this was a trip that fed my soul, expanded my dive log, and left me dreaming of the next adventure. Thank you, Cayman Aggressor IV, for setting the bar so high!

The crew, the food, and the diving were fantastic!
While I absolutely loved the warm water and almost every dive site, the food that Mar cooked for us was delicious beyond my wildest dreams. Putting it another way, Mar's cooking was so delicious that the food she cooked was a highlight of the trip. The first mate/second captain Javier's enthusiasm and willingness to give us the very excellent underwater photographs that he took of each of us was another highlight, well actually, just getting to interact with Javier was a highlight. He has a wealth of underwater photography and diving knowledge that he freely shares. Talking with Captain Billy, the very charismatic leader who clearly makes the safety and comfort of the passengers his top priority, was another highlight. Working with Sarah who was always there and willing to help with whatever one needed was another highlight. Doing the night dives with Danny was yet another highlight. Almost every dive was excellent. The waters were warm. The dive sites were well selected. The food was amazing. The crew were incredible. This was my first liveaboard experience. I can only hope that my next one, yes, I will definitely do another Agressor Liveaboard, will be as excellent as this one was.

Amazing experience.
My husband and I booked our trip before we knew I would have back surgery. 6 weeks after surgery we were on the boat. My doctor signed off so I could go diving but with limitations. I can’t carry my gear. The staff carried my gear for me every time. Without their help I couldn’t dive. When I had to skip a few they gave me ice for my back and even sat and talked with me. The food was delicious. The cabins are small but comfortable. The boat is kept clean at all times. The staff is super friendly and helpful. I will definitely book another Aggressor trip. I just got home and I’m ready for another trip! 😃

Nice trip despite reef condition
We had the option to either stick with the guide or go off in buddy groups. This was particularly good since they only had one dive guide for each dive, vs. one per 4-6 divers. The reefs weren't in great shape, especially on Grand Cayman, because a stony coral disease has gone through since the last time I visited the Caymans 10 years ago. Still very enjoyable, despite this. Dives were easy and relaxed. We spent most of our dive time on Grand Cayman; I would have preferred more time on Little Cayman.

I enjoyed seeing beautiful aquatic life in their own habitat, unmolested and unprovoked by the imposition of humans.
I had some trepidation before going on my first official sea dive. There was the natural anxiety about diving in the sea for the first time and being among veteran divers, feeling that I might be holding people back. After my first dive, I became totally relaxed and gained more confidence with each ensuing dive. Not only did the crew "take care of me" and ensured that I was aware of the priorities when diving but my fellow passengers treated me as if I was valued and did not look down on my lack of experience. I was enthralled with the underwater life and coral walls. I saw sharks, barracudas, angelfish, triggerfish, spiny lobsters, an enormous crab during a night dive, anemones, lionfish, sea turtles, and so on. I never felt panicked or rushed. People were extremely patient with me and corrected me on my buoyancy.
