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.

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.

Love the Aggressor! Such a beautiful boat with lots of amenities !
I met several really nice people that I will be diving with in the future. The diving was great - loved the warm showers and warm towels after every dive! Bailies and hot chocolate after the night dives was a great treat too. The crew was funny, helpful and very nice. Will be diving Aggressors in the future for sure!

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!!!

Fabulous crew deliver an unforgettable experience
We joked that it felt like diving boot camp—five dives a day! Dive, eat, sleep-repeat and what a pleasure! Absolutely loved the crew. Unfortunately the weather wasn’t the best, prohibited us from visiting the other two islands but Captain Sarah did a fabulous job guiding our ship to beautiful sites in Grand Cayman.

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.

Wonderful Dive Trip
Amazing experience that is only possible thanks to the experience and competence of the crew. Everything was so well organized and operation was super smooth. The diving was great even though we couldn’t make it all the way to Cayman Brac. It’s mostly wall dives but I love those. The food was excellent although I would love to have more healthy options available.

5 Star Dive Vacation!
This was my first liveaboard so I was not sure what to expect…..I’m hooked! Captain Josh Foster is an amazing man, Captain, instructor, dive master and human! Thank you for making the achievement of earning my advanced certification such a safe, informative and memorable experience! The food was delicious and abundant! The chef outdid himself!! I cannot say enough about our crew, who went above and beyond to make our vacation one of the best I’ve had. One word of warning to those expecting a cruise ship type cabin….this is, in all actuality, a dive boat, so your state room is quite “cozy”….pack LIGHT! LOVED ❤️

The Only Way to Dive
From the moment we stepped on the boat everything had been thought of. The experience of the team made this the only way to travel for the best diving experience. We had perfect weather that enabled us to see all 3 islands and dive. The food was off the chart amazing. The chef provided an array of meals and snacks that was not only delicious but it kept us well fueled for the dives Before getting off the boat we were already looking at our next dive trip with Liveaboard!

Incredible Trip
The crew was incredibly orchestrated, from the moment you get on board you feel like family. The room was tighter than I expected from the pictures but absolutely cozy. The amount they pack onto this boat is incredible. We went to little cayman which was awesome. The food was incredibly delicious, only caveat was you need willpower to say “no” there is just so much. Also I am not a fan of drip coffee so I’ll bring a small espresso maker. The only down side for me as a solo traveler was it was hard to find a buddy because it was a large family group, and I backed out on a dive because nobody was really looking out for me, but I quickly found a few buddies. I can’t say anything bad about my trip it was epic and I turned 50 on board. Next time I’d bring an espresso maker and a clothesline. Nearly perfect and the crew is so well orchestrated! Amazing 😻

Well-run with standout diving!
The crew ran a tight operation from start to finish. Schedules stayed clear and consistent, so you always knew where to be and when. The DMs led with focus and control, and every briefing set expectations without wasted time. Meals were handled with care, including dietary needs across the group, which made life onboard easier for everyone. Diving conditions lined up in our favor. We spent time in both Little Cayman and Cayman Brac, which felt like a bonus. Visibility was great, the dives stayed varied, and the overall experience was smooth from start to finish. This was a well-run liveaboard with some great personalities, and great diving!

Our first liveaboard trip, but definitely not our last!
I cannot say enough good things about the crew. Without exception, they were friendly, knowledgeable & helpful. This was our first liveaboard trip, but it will not be our last. The boat was set up perfectly. Enough room for diving equipment to be set up & everyone could get ready at the same time without getting in each other's way. Captain Josh planned the dive sites perfectly. The dive leaders were very helpful & quick to point out interesting features & creatures (large & small) during the dive as well as able to answer all those "What kind of fish was that" questions after the dives. Don't even get me started on the food! It was fabulous! Before the trip, I read a lot of reviews about various liveaboard companies & I'm extremely happy that we picked Aggressor. We will be back. Thanks to all the crew.

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!

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!

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.
