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...

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!

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.

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.

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.

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.

This trip makes you feel like you are back in the days of Jaques Cousteau's pioneering diving.
The mix of soft and hard corals in the Mergui islands is exceptional! Till date, there has been almost no bleaching. The Burma banks, situated far from land, are amazing dive sites. Giant ancient coral bommies with many nurse sharks sleeping underneath them and cruising around. There are also silver tips and a profusion of fish. The currents provided great drift dives and the visibility was excellent.

The Mergui islands are breathtaking. They are one of the most unspoiled Archipelagos in the world.. We did not see any other liveaboards during the entire trip.. Dive and cruise. They took us on a beautiful tour of the islands, the view was continuously changing..

Excellent Dive Experience In The Andaman Sea
I had a great experience during my 7 day liveaboard on the Phinisi. The dive sites were fantastic, if a bit crowded with divers from other boats. The Phinisi carries a relatively small number of divers, but some of the competing companies bring a lot of divers so it can get crowded. Our cruise director was good at avoiding the worst of the crowds. The reef life was fantastic. We had bad luck and didn't see any big pelagics, but that's uncontrollable. The dive instructors and dive masters were excellent. I enjoyed the food, a mix of Thai and western, it was tasty and there was more than enough. Overall the Phinishi made a good dive boat with all the necessary facilities. My one minor complaint - sharing 4 to a cabin wasn't the most comfortable, but we made it work.

Super nice liveaboard on the Phinisi
The highlight of the trip was of course the whale shark, which we saw, only one 5 divers and no one else around, wonderful experience.

Everything worked perfectly. Although the ship is newly used as a safari boat, the crew (Thai as well as the rest) seemed very organized and helpful. The rental equipment is completely new and of high quality. In terms of safety, it's also great. Before each dive, a good briefing with important information. The dive groups were divided according to experience level, and adjusted after the check dive and possibly later. Nitrox always 32%.

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 :)
