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.

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!

Boats and Pros: Exceeding Expectations, a Phinisi Story
The Phinisi exceeded expectations and beyond. The attention to every detail of the trip was amazing. My appreciation for the crew is unmeasurable bc they actually care. Fantastic food and no shortage of meals, saw all the marine things one could hope for, the quarters and boat were very comfortable, the rental gear was top notch and felt I was in good hands the entire trip. You know it’s the best when you don’t want to get off the boat. I hope I get another opportunity to dive with Phinisi and crew again someday. Thanks for the memorable experience! 10/10, A+, 5 stars.

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 dives, great food, great staff.
Dives were so much fun. The dive masters were relaxed but still took care of us without babying us. After every dive, the crew would provide you with hot drinks and we were fed five times a day.

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.

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.

I'll try once again!
The first liveaboard in my life. It was not too long and not too short, 5 days and 4 nights. Storm was coming but we didn't worry about that, because of the stable crew and dive masters. I just really recommend this if you are on your first trip. Above all Sai's cooking will block sea sickness, I swear.

Easiest to spot at every site!
The entire boat, crew and guests were super friendly and made the trip better. It was easy to sit and talk to anyone/everyone. The islands and sunsets were very photogenic. The only bummers were visibility (lots of plankton) and some strong currents but that means big pelagics, so it wasn't much of a bummer. I would definitely recommend The Phinisi (or Siren fleet) based on this trip.

1. The crew, both dive and boat were so helpful. When I had equipment problems they fixed them very quickly or swapped in rental gear. 2. The food! Si (the chef) made sure the vegetarians and celiacs had special food without compromising on quality or diversity. 3. The variety of underwater life! Mantas, whalesharks, turtles, sting rays, octopuses, reef sharks, all the triggerfish and so much more.

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.

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.
