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.

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 trip
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.

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

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.

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.

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.

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.

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.

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.
