Probably the best boat crew I’ve experienced in the small number of liveaboards (7) completed. Bobby, Janine, Tu were excellent as well as the rest of the crew. Loved the chef and his assistant! Great variety of meals as well. Didn’t see any mantas or whale sharks this trip, but it was still an awesome adventure.

Up to the usual Aggressor standard.
Very well organised by a great crew lead by Bobby. The boat is very clean and well equipped with a spacious dive deck although the cabins are on the small side. The diving schedule is well planned and executed by great dive guides - everything runs on time. Food is of a high quality and there is loads of it - no one will go hungry!

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.

Best dive trip
I had an incredible time as the aggressor in Thailand with Bobby and his staff. Their staff was incredibly helpful, gracious, generous, supportive, and most importantly, they went above and beyond. I’ve never had anyone so attentive to my needs. They made sure I had my fins on for every dive, my camera, and that I was well-fed and enjoying myself. This experience was truly exceptional, and I can’t express how much I loved it. On top of that, I celebrated my birthday on the ship. Little did I know, they had gone to a nearby city to get a cake, and we celebrated on one of the nights. It was a very special and amazing moment. Again, I had such a great experience that I eagerly anticipate my next trip to Thailand to explore the north side and dive. .

Fantastic surprising week of diving!
We had a wonderful diving week that was perfectly taken care of. Nothing to complain about! Only a lot of praise for all the staff and the weekly schedule. The dives were beautiful. Lots of coral, lots of fish from small to large.
Recommended for
The dives were perfectly arranged and tailor-made who wants to make which dive. Super guidance. Everything was perfectly taken care of on board. After every dive you were completely pampered. The division of the days was well prepared and when unexpected wind or bad weather came, there was good improvisation.

Overall was as expected. Good boat crew. The coral in PhiPhi is struggling and so the diving was less spectacular. Good was good but not extravagant.

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

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.

Very well organised and high quality Liveaboard
The 4 dives in Richelieu Rock were impressive in the abundance and diversity of marine life, soft and hard corals. The food on board was much better than what i used to get in other liveaboards. Any type of cooked eggs for breakfast, Thai for lunch, 3 course meal for dinner, nice white wine, all drinks are complementary. The service was very attentive. All staff help out and are very smiley. Even the chefs help out take the divers gear out between meals. Jinni the stewardess looked after passengers like a mother, handing over towels, food and drinks. Clive the cruise director is a well of diving experience and maintains the cruise, diving and hospitality standards to a very high level. He is also relaxed and friendly. The dinghy drivers were highly skilled at dropping us off and picking us up even by night and very helpful. My only negative feedback is that the wifi should be upgraded to handle the data needs of passengers and staff as it didnt work very well even when mobile network was available from the shore.
