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.

Best experiences

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!

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.

If you want to be sure that none of the other boats around you in the Similan Islands looks more spectacular and has a better crew, spend your week's diving on the Phinisi! Simply brilliant and I woul

My personal highlight, which showed the great level of organization and 'caring' of the owning company of the Phinisi, was when my entire dive equipment and luggage, which had been lost by the airline on the flight to Phuket, was handed over to me by the crew of the sister ship 60 offshore in the Andaman Sea. Unparalleled Service!

A wonderful break

Turtles and wonderful dive sites. The stay onboard was also great with less divers than capacity and therefore made the cruise something special, privileged.

I'll try once again!

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.

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.

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 :)
