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!

Crew made it worth it
The diving in the north with beach trips were great. The staff and crew were always very helpful and made it really feel like a vacation.

- The helpfulness and the friendliness of the crew was awesome. The selection of food was great (if you like Thai food/seafood). The cabin was larger than other liveaboards I’ve been on.

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.

Great time all around.
Everything was wonderful start to finish on this liveaboard. The diving was incredible and all the rest of the time we were spoiled with great food, comfortable facilities, and a really helpful, friendly, crew. It was our very first liveaboard and we felt lucky to have such a wonderful time.

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.
