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!

This Liveaboard will definitely be a repeat one for me!
I had a truly epic time on this Liveaboard and will definitely bring doing this one again! The visibility was great and the deep passageways through the corals were the most exciting part for me.

Go Dive the Caymans!
Overall - great trip. Lots of fund with a great group of people! The main/dining room was a central meeting, dining and watching videos and while it is nice to sometimes come out of the sun to a cool room, but my only criticism would be that if it got any colder in there it was going to start snowing! :-) But I cannot find enough good things to say about the crew, all of them! (in no particular order): Josh, Billy, Chelsea, Rodel, Jay, Fabian and Daniel Thanks all for a memorable trip to the Caymans!

What an amazing adventure; in luxury and comfort!
This is my second Aggressor Live-aboard, and they do not disappoint. It is a whole experience of Quality and Adventure. If I had to critique anything, I would suggest that the rooms on the Cayman Aggressor IV have Drawers or a Hanging Locker for clothing. We made do, but it is very difficult to stay organized without a designated place for your things. All that was afforded us was one shelf. But in the big picture, this critique is such a minimal issue. I would definitely recommend everyone who dives to go on the Aggressor line; and I will definitely be coming back. I would like to stay on all your boats, in all your locations.

- The Crew were incredible. The entire crew were always going above and beyond to ensure we had anything we needed to make this trip the best. They were so good, I can't single anyone out.. Food was quality and plentiful.. The Adventure of diving was incredible. Even though it is noticeable that the corals are suffering, there is still so much life, with the fish and other sea creatures..

- The crew, hands down. They were so knowledgeable, personable, fun and happy.. You can help yourself to a plethora of snacks, fruits, coffee/sodas/beer/wine at any time. The crew really tried their best to get us the best dives given the weather.

I may not take another day boat or shore dive, liveaboard only way to dive.
While a tropical depression sent us back early from Cayman Brac & Little Cayman, we still had a great trip. The trip cut short by storm by a couple of days. Slow moving storm actually went west to Mexico - Honduras at next to last day, too late to continue diving. Suggestion: lay out all clothes you plan to take, then pack half of the clothes. 2-3 bathing suits, 3-4 shorts, a couple of rash guard long sleeves, one pair of shoes (to wear on plane), and maybe sandals, a couple of short sleeve t-shirts, and something to wear when cool in dining room. I went barefoot entire trip, only wore diving booties when diving. Diving great, only got chicken one dive. LB

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!
