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.

awesome, even for a first-timer.

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)

The family-like bonding amongst thr guests, crew and staff. Chill-out nature of the schedule (we are afterall on a holiday right), and people care for guests who were ill.

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.

Solo diving in the riches of Richelieu Rock Surin and Similan

Absolutely amazing crew on board the Phinisi. With Marco lead dive instructor giving in depth briefing, good explanation and organisation of groups. My dive guide Guitar was super friendly and knowledgeable. She was put in some difficult situations with environment and other more demanding, less experienced divers. She handled herself well in some non-favourable events. The crew were all amazing, from captain and his deck team to the galley, hospitality and host. They all made the effort to make this a memorable liveaboard and even had a chance to put the sails up for photo opportunities. Unfortunately, during this time of year and luck we were visited by the green monster. Something mother nature cannot change. Best dive site was Richelieu Rock, an abundance of life underwater. Incredible site. Would 100% recommend anyone to join the Phinisi on their next liveaboard trip in Thailand!

Wonderful diving and crew

This was our first liveaboard trip, and the Phinisi did not disappoint. We had a great experience onboard—absolutely nothing to complain about. The crew did everything possible to ensure a safe, fun, and relaxing trip. The food was amazing, with a ton of healthy options to choose from.

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

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.

Very pleasant and positive experience

Little bamboo sharks hiding in almost every crack on Koh Doc Mai dive. Loved the “Chimney” in Koh Haa. Overall very relaxing and enjoyable diving trip. Definitely would recommend Phinisi as a great liveaboard.
