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!

This crewed ship makes divers' hearts beat at the highest level.
Each and every one of the team contributed to the great success of this trip. Without exception, everyone was friendly, attentive and took care of the customers in the best possible way. The divemaster was outstandingly good and I felt very well informed on every dive, very safe and was able to enjoy the great dive sites. The beautiful ship also turned out to be very well equipped and my cabin was also very nice! I am totally thrilled with this great diving trip!

The liveaboard of a lifetime.
This boat and its staff brought together a fantastic group of human beings with whom to spend a week diving. The accommodations and the gear were all top notch. During my time on board, I completed my advanced certification with Jonathan, who is an incredible mentor and cruise director. Also important, the staff and crew on The Phinisi are incredibly respectful of marine life and observant of the national park regulations. Highly recommend.

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.

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.

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.

Amazing boat, crew and dive sites
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.

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.

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.

Excellent Dive Experience In The Andaman Sea
I had a great experience during my 7 day liveaboard on the Phinisi. The dive sites were fantastic, if a bit crowded with divers from other boats. The Phinisi carries a relatively small number of divers, but some of the competing companies bring a lot of divers so it can get crowded. Our cruise director was good at avoiding the worst of the crowds. The reef life was fantastic. We had bad luck and didn't see any big pelagics, but that's uncontrollable. The dive instructors and dive masters were excellent. I enjoyed the food, a mix of Thai and western, it was tasty and there was more than enough. Overall the Phinishi made a good dive boat with all the necessary facilities. My one minor complaint - sharing 4 to a cabin wasn't the most comfortable, but we made it work.

Best boat crew in Thailand
Nice big wooden boat. Better than the smaller boats which I was on in 2020. Didn't have a dive guide as I only Snorkel but boat crew catered for this and made sure when possible to get us to the reefs and shallow parts. Nice that we could sleep anywhere as I couldn't stand the AC...

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!

It was a super great tour with super great people.
The whole trip was a highlight. It's all very well organized. The crew is super helpful, prepares everything for the dives before and after. All you have to do is check and dive ;) The food was super tasty. The cabins are functional and clean. Only the air conditioning is a bit noisy. But it didn't bother us as we slept on deck.It won't be our last tour. The planning is already underway: After the holiday is BEFORE the holiday.

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.
