Great dives and great boat!
I took a 5-day/4-night trip in November 2025 with Sawasdee Fasai. An excellent trip where we hit the highlights of the andaman sea. Other than some rough water the first night (which the crew handled very well) it was an idyllic few days of diving and relaxing.

10/10 Fantastic!
The whole liveaboard trip experience is the highlight of my Thai vacation. Meeting and talking with the Sawasdee Fasai dive staff. My Nitrox certification with Marcelo. Meeting Marcelo, Fhon, Frasnc, Miko and the other dive leaders. The diving. The food.

Absolutely the best liveabaord experience
I was at the Similans 12 years ago and the coral (as all over the world) was much better in those days, nevertheless diving at the Similans is still great and the best in Thailand. Richelieu Rock is still as I remembered, beautiful hard and soft coral ans loads of fish, the absolute highlight of the trip!
Recommended for
The ship was in a great condition, lot of space on the diving platform as well as on the rest of the boat. The crew did everything that was in their possibilities to make it an forgettable experience, nothing was to much for them. Diving in small groups of 4-5 divers per guide.
