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.

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.

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.

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.

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.

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.
Recommended for
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%.

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.

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!

My personal achievement of being able to deploy a SMB. Better bouyancy. First time doing night dive (and not afraid of it). The ITININRY certainly facilitated all these, nice dive masters, and accomodating guests (we just laughed over it someone made mistakes like forgetting the masks or went into the waters without fins)

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.

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 :)
