Authentic Phinisi experience
Dive gear rental on board

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.

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.

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!

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%.

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.

Crew was great. Co divers were fun. Food was awesome but wine was expensive. Saw a wide variety of sea life.

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.

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!

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.

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.

Great dive group and great food
The overall experience was great and fun. Woody helped me reduce my dive weights for better neutral buoyancy. The macro marine life was disappointing and not comparable with Indonesia. As was the camera station which was not a seperate room as is on every other Liveaboard I have joined

It was windy and the waves were strong, so the 3rd and 4th island points had a better view than Richeliurak.Whale shark manta Annaom Richeliurak is the second person to leave work.

It was a three-meal buffet style, and the drinks were free, and the diving deck was spacious with individual seats, so it was good, and even if the staff turned the suit inside out and took it off, they did everything right away and hung it up.
