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.

Thai experience is friendly & inviting

I was fortunate to have a room by myself. I had an incident on a dive site when a 3rd diver joined my pairing where he left me at a dive site, the DM was busy helping a difficult diver decent & current drifted me away from the group as I descended quickly, my normal buddy diver was going down slower due to ear sensitivity. Afterwards the DM/cruise director handled my frustration with the situation professionally/quietly with me & didn't interrupt the trip being enjoyable.

The Crew Was Great

We had issues with visibility and current on our trip. The crew was very good about assessing the current conditions and move the boat to more favorable conditions, even if that was a couple hours away. We did all drift diving and the crew was very quick to pick divers up via Zodiac. Very Helpful!

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.

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!!!

Great above the water, some poor coral protection practice while diving

Diving visibility was pretty poor throughout the trip. Dive clients predominantly photographers with some poor practice around coral protection.
