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.

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.

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.

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.

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!

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.

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.

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!

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

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...

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.

Excellent trip where to sharpen your diving skills
I needed more dives before attempting Raja Ampat and spots if such level, farther away. Excellent place where to gain experience, safely, in comfort, at a reasonable price (what it would cost you per dive in Europe but on the beautiful Phinisi, all inclusive, with minimal equipment hassle, and 27C waters at 20m). We could not see any pelagics though, and the sea was choppy, preventing us from exploring Richelieu Rock (we just went once in low visibility). I've learnt nothing is guaranteed on the seas over several days. But overall excellent experience, certainly at my level.
