The 37m Thailand Master is a purpose-built sailing liveaboard designed by divers, for divers. Accommodating up to 18 guests in 7 air-conditioned cabins, it offers comfortable en-suite bathrooms with hot water, fresh towels, and storage space. Laid out to maximize comfort and functionality, Thailand Master provides the perfect balance between relaxation and serious diving adventure.

Guests can unwind on the sundeck lounges or enjoy meals in the indoor and outdoor dining areas, where meals are served buffet-style with vegetarian and other dietary options available. Between dives, relax with a book from the onboard library—ideal for identifying marine life spotted underwater—or enjoy movies and games in a welcoming social atmosphere designed for like-minded divers.

The shaded dive deck offers personal setup areas, dedicated storage, rebreather support, and nitrox refills. Rental equipment is available, and a diving tender ensures easy access to sites. Itineraries explore Thailand’s top dive destinations, including Koh Bon, Koh Tachai, Richelieu Rock, Koh Phi Phi, King Cruiser, Hin Muang, and Hin Daeng. From December to April, the Thailand Master also ventures into Myanmar’s spectacular Mergui Archipelago, visiting renowned sites such as Black Rock, High Rock, Tower Rock, and Torres Island.

Best experiences
This is one of my best experiences in my life. The boat was amazing. Cabins clean and very comfortable. Food was amazing, good mix between western and Thai food. Although we didn’t see any big fishes the diving was amazing. To do my AOW here was the best choice I’ve ever made. And all honor to my dive instructor, Ping. He made it so easy to complete my course, thank you. I’ll definitely come back sometime and will recommend this to all my dive buddy’s!

Second time for me
There are so many things about this trip, it is hard to state any one on its own, the crew were great and nothing and I mean nothing was to much hassel, and this applies to any time in the day or night. the diving was great too, there are so many reefs and all have their own unique personality if you can attibute that to a reef, for me it was the crew on the boat that made the difference and will be diving with them again.

Incredible: everything!
Marco the trip leader is a true professional and he and the rest of the staff bend over backwards to make it your best trip ever. The dive sites were good, avoiding the day trip boats very well. The food was out of this world, and the dorms were very comfy with softer beds and cold AC.

Super nice liveaboard on the Phinisi
The highlight of the trip was of course the whale shark, which we saw, only one 5 divers and no one else around, wonderful experience.
Recommended for
Everything worked perfectly. Although the ship is newly used as a safari boat, the crew (Thai as well as the rest) seemed very organized and helpful. The rental equipment is completely new and of high quality. In terms of safety, it's also great. Before each dive, a good briefing with important information. The dive groups were divided according to experience level, and adjusted after the check dive and possibly later. Nitrox always 32%.

Livesboard that lives up to its dual mission of safety and the enjoyment of guests. Lovely diving that is not overly challenging. No big stuff but an abundance of marine life on healthy corals. Highly
We had a relaxed and enjoyable time on the Phinisi. All the crew are very friendly and welcoming and we felt in safe hands. They could not have done more.

Great 10 Day Journey!
After missing out on Mantas on the northern part of our trip and expecting to not see any mantas at all, we spotted an absolute beauty unexpectedly that made the diving portion of our trip. Hats off to the crew who put up with us over Xmas and New Years - they were awesome and welcoming and really made our trip enjoyable!

Awesome diving, on a beautiful boat with a wonderful crew
Just back from an amazing 7D/6N dive trip aboard the Phinisi, visiting the Similan and Surin islands with my dive buddy. The best dive site (by far!!) was Richelieu Rock. We dove there four times, and I would have been happy to have just dived that site over and over. Our dive guide was Amelie, and she made sure to always find something cool and obscure on each dive. The rental gear was brand-spanking new, and so was pretty much everything else on this newly renovated boat. The boat is beautifully appointed, and we lacked for nothing. My buddy and I felt like kings, lavishly attended to do by the entire crew throughout our trip; from delicious and bountiful meals to assistance getting in and out of our dive gear. Deano’s dive briefings were entertaining and amazingly accurate. The whole team oozed experience and I highly recommend this boat, crew, and itinerary to anyone seeking to eat, sleep, dive, repeat :)

Did not want it to end.
It was great a great dive trip. Got up close with cuttlefish. Saw an assortment of so many fish, sharks, scorpion fish, pipefish, angel fish, turtles barrakudas, one crab was so decorated he looked like he was going to mardi gra. The list went on and on. The water was murky, some of the days but visibility still not problem.

Look no further! This was one of the best diving experiences i've had to date.
Apart from the lucky visit by a 5m Manta Ray. Everything about this trip was perfect. I had planned to lose a bit of weight, However the food laid on was too good not to have seconds :). Super friendly crew and a very chilled and relaxed atmosphere all over the very spacious boat. Can't wait to return again to the Phinisi.

awesome, even for a first-timer.
My personal achievement of being able to deploy a SMB. Better bouyancy. First time doing night dive (and not afraid of it). The ITININRY certainly facilitated all these, nice dive masters, and accomodating guests (we just laughed over it someone made mistakes like forgetting the masks or went into the waters without fins)

The family-like bonding amongst thr guests, crew and staff. Chill-out nature of the schedule (we are afterall on a holiday right), and people care for guests who were ill.

If you want to be sure that none of the other boats around you in the Similan Islands looks more spectacular and has a better crew, spend your week's diving on the Phinisi! Simply brilliant and I woul
My personal highlight, which showed the great level of organization and 'caring' of the owning company of the Phinisi, was when my entire dive equipment and luggage, which had been lost by the airline on the flight to Phuket, was handed over to me by the crew of the sister ship 60 offshore in the Andaman Sea. Unparalleled Service!

Diving around Surin island was amazing. The crew is really working for passengers to have the best possible trip. We made a visit to a Moken village one day we couldn’t do a dive due to weather conditions. I hope I can go back and do another live aboard in the same boat.
