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.

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!

Easiest to spot at every site!
The entire boat, crew and guests were super friendly and made the trip better. It was easy to sit and talk to anyone/everyone. The islands and sunsets were very photogenic. The only bummers were visibility (lots of plankton) and some strong currents but that means big pelagics, so it wasn't much of a bummer. I would definitely recommend The Phinisi (or Siren fleet) based on this trip.

1. The crew, both dive and boat were so helpful. When I had equipment problems they fixed them very quickly or swapped in rental gear. 2. The food! Si (the chef) made sure the vegetarians and celiacs had special food without compromising on quality or diversity. 3. The variety of underwater life! Mantas, whalesharks, turtles, sting rays, octopuses, reef sharks, all the triggerfish and so much more.

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 :)

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.

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

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.

The whole trip was a highlight. It's all very well organized. The crew is super helpful, prepares everything for the dives before and after. All you have to do is check and dive ;) The food was super tasty. The cabins are functional and clean. Only the air conditioning is a bit noisy. But it didn't bother us as we slept on deck.It won't be our last tour. The planning is already underway: After the holiday is BEFORE the holiday.
