Great boat with great staff. Fits a huge amount of divers without getting crowded. Very modern and luxurious. The Similans are awesome as expected, really got the impression the staff knew where to find all the good stuff. Think we had 7 dive masters with us in total.

A highly recommended boat.
The boat is spacious, the budget cabins are small but functional. The food is great, the organization and support all around top. The highlight is diving at Richelieu Rock, with really lots of fish. The rest of the dive sites were ok. The visibility was about 10-15m. A normal dive here takes about 50-55min.

Magical!
What an amazing experience with Sawasdee Fasai! I loved every minute. The diving was beautiful with great visibility and variety of underwater life. Loved the corals and the abundance of fish especially at Richelieu Rock which is now one of the best dives of my life. All the dive sites were great however and I enjoyed the trip immensely. The crew were fantastic and run a great operation. Nothing was too much for them, always helpful and smiling. Food was delicious. Budget cabin was more than adequate. Shout out to Rob our excellent divemaster who took great care of our group and always pointed out interesting things underwater. Would recommend this trip 100%.

Every time again
It was our second time on this boat on a liveaboard – and this time everything was absolutely convincing. The organization was once again top, the crew professional, helpful and present at all times. The diving spots were excellently chosen and again offered unforgettable and impressive experiences under water. For us, it is confirmed: This was certainly not our last liveaboard on this boat.

This live aboard was amazing. The boat is in great condition with comfortable amenities. The food was delicious and catered to all dietarles. The crew were second to none. V experienced/knowledgeable divers that made each dive run smoothly and safely. The dive sites were excellent - good corals, lots of fish, some rays, etc. There is no wifi on the boat, but I had cell reception 75% of the time. The Surin Islands were out of range.

Great experience & crew
Great boat with plenty of space, experienced crew and fine food. It takes very good care of the guests. The diving material is in good condition. The nights were very quiet and restful with the exception of the first night (approach to Dive Spot). Only on the lowest deck (Budget Cabin) it smells a bit at times.
