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.

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.

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.

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.

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!

Unforgettable Dive Adventure - Easter 2024
My recent experience aboard this liveaboard surpassed all expectations and left me with memories to cherish for a lifetime. From the moment we stepped on board, we were greeted with warm hospitality and professionalism from the entire crew. The staff's extensive knowledge of the dive sites and dedication to safety reassured us throughout the trip, allowing us to focus entirely on the incredible diving experiences that awaited us. The liveaboard itself was a comfortable and well-equipped vessel, providing all the amenities one could need for a week-long dive excursion. Our cabins were meticulously maintained. The communal areas, including the lounge, dining area, and sundeck, were inviting spaces to relax and socialize with fellow divers between dives. But it was the diving that truly stole the show. Each day brought new and breathtaking underwater landscapes, from vibrant coral reefs teeming with marine life to exhilarating drift dives along dramatic walls and pinnacles. The dive guides were knowledgeable and passionate about marine conservation, enriching our dives with fascinating insights into the underwater ecosystem. One highlight of our trip was the opportunity to embark on night dives, where we witnessed a whole new world come to life beneath the surface. The nocturnal marine creatures were nothing short of mesmerizing, providing an unforgettable experience that we'll cherish forever. Of course, no dive trip would be complete without delicious food to fuel our adventures, and the onboard chef certainly delivered. From hearty breakfasts to gourmet dinners, every meal was a culinary delight, with plenty of options to accommodate dietary preferences and restrictions. In conclusion, my experience aboard The Phinisi Liveaboard exceeded all expectations, thanks to the exceptional crew, comfortable accommodations, and unforgettable diving adventures. Whether you're a seasoned diver or new to the sport, I cannot recommend this liveaboard highly enough for your next underwater expedition. Special shout out to Victoria who was an amazing Dive Guide and quite literally runs a tight ship! - Pradeesh

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 :)

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.

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!

I enjoyed my first trip to Thailand, I have dived in several locations in 2023, 5 locations and loved them all but my trip on the Phinisi was the best of all, loved the boat and the crew were great, and and yes once again loved the food. The dive sites were varied and great with plenty of life, on one trip had to push the fish out of the way so I could see my buddy.

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...

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.

My first liveaboard couldn't have been better!
My first liveaboard couldn't have gone better. The crew was extraordinarily helpful and friendly, the dive guides super personable and the food was really good. The ship itself was also very cozy. Everyone always tried to make sure that you were satisfied. The dives were also super nice, and I also felt super safe with the dive guides (only had 20 dives before doing another 18 dives on the Phinisi - so I wasn't that experienced). Also the dive crew, who always prepared the equipment for us, and led us with the Zodiac to the dive sites, was great. All in all, a really great experience that I wouldn't want to miss!
