Nice experience
He said it was an unforgettable experience. It's the first time I've done a liveaboard and I've loved it.The best thing has been the professionalism and kindness of the whole team (instructors, kitchen, boat boys...), with Kwan at the helm, who make everything very easy for you to enjoy. In addition, on the last day we saw a video that had been edited with images of the dives carried out; An unforgettable memory.I was in the Master cabin, very comfortable and spacious and the meals were plentiful as well as good.Special mention for Mirella and Dani. It was a real pleasure to meet you. Hopefully we can repeat it another time.

My partner and I did this Livaboard in Dec 2025 and had the most incredible time. The trip was organised well, the diving was outstanding with great variety, the crew were lovely and helpful, the food spread was delicious with a variety of options (the also catered for dietaries very well). I completed my Advanced course and the instructor / guide (Mici) was absolutely amazing and an awesome teacher. I learnt loads and felt very safe. This was one of the best experiences of my life, thank you to all the crew.

Absolutely loved this liveaboard!
I had such a great time on my trip! The whole thing was so well organised, and the dive leader explained every dive briefing so clearly with a great sense if humour. The boat was at maximum capacity but it still felt really spacious and comfortable for all the guests and crew onboard. The boat was really clean and the food was delicious. Amazing choice of buffet options. Towards the end of the trip I had to skip couple meals because we were so well fed that I couldn't bring myself to consume any more calories haha. The crew were also amazing, they went out if their way to make sure you were safe and looked after. I highly recommend this liveaboard!

A world-class diving adventure defined by incredible service and great vibes.
My time on the Sawasdee Fasai was an absolute delight from start to finish. Exploring iconic sites like Richelieu Rock and Koh Tachai was breathtaking, but what truly set this trip apart was the life on board. The crew went above and beyond to ensure we were well-taken care of, always greeting us with smiles. Between the great meals and the well-maintained, organized facilities, I could focus entirely on the diving and relaxation. It was a seamless blend of adventure and comfort.

I can highly recommend after doing three trips onboard!
This was my third trip on the Sawasdee Fasai and will definitely book again! If the weather allows it, you can do 4 or even 5 dives at Richelieu Rock (my favorite) and also a few on Koh Tachai (my second favorite). The last night they do a BBQ and small party on the upper deck which is super nice!
