Amazing Dive Vacation
We were luck to have only 10 guests on board so all single travelers had their own cabin which is pure luxury on a Liveaboard Tour! The cabins are small but good enough for sleeping exhausted after a day of diving. The Housekeeping and food supply was awesome. Our cruise director Glenn did a great job in keeping us out of the crowds during our dives (esp. at Richelieu Rock!). Our Dive Guides were superb, I am not super experienced and felt very safe during all the dives, even with varying conditions. All in all: highly recommended!!!

A fantastic dive experience!
Being guided by the amazing dive masters to see so many wonderful marine creatures. The ambiance on the boat was fun and enjoyable because of the other divers and our mutual love of the ocean. This is a very interactive crew, they spent an amazing amount of time ensuring our comfort and enjoyment. We received extensive briefings, safety is number one concern, and the boat and dive schedule was run so efficiently to ensure maximum dive time. A special thank you and recognition to Cruise director Glen, dive guides, Leann, Natalia, Dan, Jai and Camille. Your are professional divers and fantastic people. The facilities, dive deck and support crew were excellent and the food delicious and plentiful thanks to Ginny and her staff. I highly recommend taking a trip on the Thailand Aggressor with this great crew.

A Top-Class Liveaboard Experience: The Thailand Aggressor
I recently had the pleasure of joining the Thailand Aggressor for a dive trip, and it is truly a liveaboard in a class of its own. From the moment we stepped on board until our departure, the experience was absolutely flawless. Exceptional Crew & Service: The crew was incredibly friendly, highly competent, and always ready to help with a smile. They truly spoiled us—everything was prepared and set up for us in advance, making the whole diving experience effortless and deeply relaxing. Fantastic Dive Guides: The dive guides were super! Their local knowledge and professionalism made every dive feel safe, engaging, and exciting. Outstanding Food: The kitchen deserves a massive compliment. The food was absolutely incredible—abundant, delicious, and exactly what you need after a long day in the water. Breathtaking Dive Sites: The diving itself was gorgeous. We explored some stunning underwater landscapes, but the absolute highlight of the trip was Richelieu Rock. It was breathtakingly beautiful and teeming with life. If you are looking for a premium, hassle-free diving holiday in Thailand with top-tier service, I cannot recommend the Thailand Aggressor enough. I would return in a heartbeat!

Best liveboarding in Similan!!
Testimonials for Koreans Diving 5 times a day, asked for permission to do it 4 times a day due to sea conditions. You can dive without a circle. All dives last at least 50 minutes.Beer and soft drinks are free, so you don't have to worry about it. There is even sparkling water.The facilities are good, friendly and everything is good. However, the price is high compared to other tours

Great trip with minor shortcomings
Very well run ship with extremly good food. Everyone is doing their best to give you a good trip. Very well planned dives overall but climate changes have left their marks everywhere. I had hoped for better reef health and more diversity in wild life and was disappointed but the ship/crew can do little about that. Yes Agressor is costly but especially with discounts I would is worth it.

Richelieu Rock has earned its reputation
The boat is getting on in years. Both cabins and common rooms are rather small. Service, food and helpfulness of the crew was excellent. The diving restriction to 50 minutes would not have been necessary. Sometimes the reefs are hardly recognizable and it is more of a larger collection of gigantic stone structures, but this is compensated for by the highlight of the tour, the Richelieu Rock.
