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.

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.

Hands down, incredible trip!
An absolutely phenomenal trip!! The best crew (dive masters and deck crew), the captain, and chefs/housekeeping! The boat was the most beautiful on the ocean and the crew (all sides) were phenomenal. The food and snacks were delicious and never ending - something all of us on board were so happy about! The dive crew and dive deckhands made it so we had to worry about absolutely nothing but the dives! I can honestly say, some of the best 5 days of my life were spent aboard the Phinisi!

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...

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.

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.

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!

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!

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.

A fantastic week aboard a great boat
The crew, dive guides and other divers are what made this trip enjoyable. The Andaman sea is not abundant with macro life, so the diving was not my favorite but that being said, we had a fantastic trip. The boat and crew made it very fun.

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

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!

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.
