Best boat crew in Thailand

Nice big wooden boat. Better than the smaller boats which I was on in 2020. Didn't have a dive guide as I only Snorkel but boat crew catered for this and made sure when possible to get us to the reefs and shallow parts. Nice that we could sleep anywhere as I couldn't stand the AC...

Excellent crew

Fantastic, skillful and super friendly crew was the highlight of this liveaboard. Excellent food also. 4 dives a day is a lot but everything worked seamlessly! Thank you!

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.

Enjoyed A Happy Week in The Phinisi

It was a happy and safe trip with this beautiful boat. We had total 5 DMs for 15 divers, each group being small and efficient.

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 :)

Meine erste Tauchsafari hätte nicht besser sein können!

Meine erste Tauchsafari hätte nicht besser verlaufen können. Die Crew war außerordentlich hilfsbereit und freundlich, die Tauchguides super sympathisch und das Essen war richtig gut. Das Schiff selbst war ebenfalls sehr gemütlich. Alle waren stets bemüht, dass man zufrieden war. Auch die Tauchgänge waren super schön, und ich habe mich mit den Tauchguides auch super sicher gefühlt (hatte erst 20 Tauchgänge, bevor ich auf der Phinisi weitere 18 Tauchgänge gemacht habe - ich war daher noch nicht so erfahren). Auch die Tauchcrew, die das Equipment immer für uns vorbereitet hat, und uns mit dem Zodiac zu den Tauchplätzen geführt hat, war spitze. Alles in allem eine wirklich tolle Erfahrung, die ich nicht missen möchte!
