Pristine corals, varied marine life and extremely comfortable boat - a good week!

Dives in the marine park, especially Chain Wall and Half Moon Caye dive sites, were wonderful. We had not expected the coral to be so colourful and pristine - so much prettier than we anticipated. Also a good mixture of marine life from big reef sharks and eagle rays to plentiful small fish, crustaceans and octopus. The boat was the most spacious we’ve experienced on a liveaboard - very comfortable. And the food was outstanding. The only reason I didn’t give the diving 5 stars above is the lack of dive guiding - it was fine for us as experienced divers in easy conditions, but for less experienced divers in current, I imagine safety could be an issue.

Big animals, sharks, rays, turtles. On one dive we came across a bait ball that you could swim into, it was incredible. The only downside was visibility could have been better on some dives.

Good way to dive Belize

Here are some suggestions Play music, have more top deck activity, or feature a movie some nights so that we can let loose a bit and mingle. Do some type or organized exercise, like yoga or Pilates to stretch every day. Have some mats so we could do on our own. Show video or slideshow to discuss the sea life we witnessed every day, make this a little more educational. deal with hot showers that are scalding and only dribble cooler water. Don't move boat after 11pm, engine noise is too loud and won't allow anyone to sleep. Have more flashlights available for night dives.

Food and friendliness of staff was tops! The dive sites were good but algae and longish and warming waters are definitely taking it's toll.

Great service, food, drinks and diving; boat could be rejuvenated

The diving at lighthouse reef seemed much better than at Turneffe. Would be great to do more than two dive sites per day if weather permits. Some of the crew were excellent as divemasters, kept everyone together and pointed out animals, whilst some of the crew disappeared off sometimes (not naming any names!). The rooms were very comfortable however a few things didn't always work such as air con etc. Food and drinks were much better than expected, hot showers and fintastic service much appreciated. The efficiency of getting divers in and out of the water safely and comfortably was great. The time spent at the dock after the last dive on the Friday seemed wasted, could we not have explored one of the islands instead?

All of the diving. It was amazing to see all of the marine life. As a new diver I also learned more skills and became very much more comfortable in the water. I wish I didn't have to go!

Excellent Experience

The boat is fairly well set up, the camera tables are a bit small though but still ok. Plenty of rinse buckets on the deck for various equipment. The hot showers and hot towels are very nice when coming out of the water. Their "fintastic" fin removal service in the water is great, makes it so easy - sometimes its just the little things. Divemasters seemed to be fairly knowledgeable and were fun to dive with. Beds were comfortable and Rooms were clean just a bit older feeling. Food was always good, I don't ever remember being hungry.Diving was pretty decent, no current and saw lots of fish, big and small. I will definitely plan to go on my next trip with Aggressor as well, it was a good experience all around

Thanks to the Belize Aggressor IV crew for a fantastic week diving and amazing hospitslity.

All around great week. Great group of people - passengers and crew! Captain Alex and his crew did a great job navigating the weather to ensure we had great diving all week. The option of following the diver master or simply diving with your buddy worked well. The food was amazing all week. The crew were very friendly and worked so hard. I would recommend this trip to others. Just one note... the dive masters are no longer allowed to kill Lionfish as some customers were complaining... There were a lot of Lionfish... and the practice of culling them should be permitted.

It was a great experience with great dives, food, and new friends.

Relaxed atmosphere and the flexibility of the staff. Food was fantastic. Dive sites were really great and guides pointed out items of interest. There were really far too many lion fish at every site taking over the reefs. Should have competitions to keep the population under control.

A.MA.ZING!!!!!! More than exceeded my expectations!

Celebrated my 100th dive on this trip!! Went w my cousin to commemorate October 16 (which should have been her late husband's 60th bday)--Eddie went out of his way to make this day special. The whole crew is terrific but Eddie is really the heart & soul of the boat!! Loved the night dives seeing all the critters that aren't usually out during the day. Loved the eat-sleep-dive-repeat life!! Thought being off the grid (& away from electronics) would be hard---it was wonderful!!!!! Your rating system only goes up to 5 stars but I would give the Aggressor IV & crew 10 stars!!

The liveaboard served the purpose of why I chose to go to this trip. To have a wonderful, safe diving and a lot of it. The crew couldn't be more helpful. All I had to do was ask and they would do their best to make it happen. Highly recommend this trip!!

More than I ever expected

Captain Eddy was very careful about making sure the sites were safe to dive. If the water was choppy he did not waste any time moving to a safer site. We all know that most dive injuries are when you get back on the boat. Loved the "Fintastic Service" while getting on board. It makes it much easier. Hot showers were amazing at the back of the boat. Dive Masters were very watchful. Jerry is an amazing cook. I love to cook myself and found time hanging out in the kitchen very exciting. Now who can boil up perfect pasta for over 20 people--that is talent!

Absolutely fantastic

I really don't see how it could have been any better. The crew were welcoming, warm, engaging and supportive. Jerry's talents in the galley were astounding. Every meal a triumph. Special thanks to Captains Eddie and Meaghan, and dive masters Simon and William, whose skills and experience made sure we were safe and comfortable. We wanted for nothing. Great value! First rate! Top shelf!
