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.

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.

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...

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!

Little bamboo sharks hiding in almost every crack on Koh Doc Mai dive. Loved the “Chimney” in Koh Haa. Overall very relaxing and enjoyable diving trip. Definitely would recommend Phinisi as a great liveaboard.

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!

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.

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.

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.

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

Outstanding, such a hard-working crew, exceptionally high standards!
I cannot recommend the Phinisi as a liveaboard experience more enough - this was the most incredible and professional liveaboard I have been on. From the safety briefings, to the dive sites, to the food, the onboard pharmacy, the aesthetic of the wooden boat (with functional sails…!) it was all amazing. The crew are incredibly friendly, professional and fun - the boat is so spacious with lots of areas to hang out and have space from other members, and the cabins are all air conditioned with en suites and so comfortable! The diving was beautiful with Richieu Rock being a stand out dive site - highly recommend taking the crews advice and getting up early as the site can become crowded with lots of divers - but it is so worth it. We didn’t have as many big fish i.e. mantas, whale sharks but we went early November which is slightly out of season - and sadly the water was very warm (the bigger fish liking cooler water). All in all an absolutely outstanding experience with the crew making the effort to put the sails up on our last day which was so special - and it truly is the most beautiful boat on the Andaman Sea!

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.
