Thailand liveaboard highlights

Liveaboard diving in Thailand is centred primarily around the Similan Islands, a chain of 9 small islands with white sandy beaches, located off the west coast of Peninsula Thailand. Surrounded by the rich waters of the Andaman Sea, diving in the Similans is without a doubt some of the best that Southeast Asia has to offer. Beautiful reefs, sleepy leopard sharks, majestic mantas and frequent whaleshark encounters are just a few of the highlights. Macro creatures include seahorses, cuttlefish, shrimps, nudibranchs and pipefish. With year-round tropical warm water, exceptional underwater visibility, diverse underwater seascapes, and a wide variety of marine life, Thailand provides ideal conditions for divers of all experience levels.

Amazing beaches

Thailand borders 2 seas: the Andaman Sea on the west side and the Gulf of Thailand on the east coast. While both seas offer fantastic diving, the Similan and Surin Islands, Phi Phi Islands and Richelieu Rock in the Andaman Sea are the most famous and diverse.

Richelieu Rock is a signature dive of the Similan & Surin Islands itineraries. Brimming with a vast array of colourful marine life, it’s a dive you can do over and over again without getting bored. 

South of Phuket, dive into the beautiful seascapes of Hin Daeng, Hin Muang, Koh Haa, Koh Phi Phi, Shark Point, Anemone Reef and the King Cruiser wreck. Across the region, you will find gorgeous caverns and swim-throughs, turtles, reef sharks, giant moray eels, impressive schools of snappers and, for the lucky ones, a whale shark, manta rays or something completely out of the ordinary. No matter which itinerary you choose, a world-class diving experience awaits you in Thailand.

Thailand Master, May 2026
what an amazing week with a great team of guests onboard. From the moment I stepped onboard the reception was welcoming and great, instantly making me feel at ease as I was going as a solo diver. The crew are absolutely top notch, from Cruise Director Marco, the dive guides, chef Bee and assistant chefs, hosts, housekeeping, boat crew, engineer all so polite, welcoming and nothing is too much trouble for them morning, noon or night. Thanks again for an awesome and memorable trip.

Holy cow! Everyone on this ship worked so hard. Every meal was phenomenal and flavorful. The staff were so sweet and accommodating. the linens and pillows on the bed were really nice. We would get up every morning, fix our latte and have a bowl of yogurt, granola and fruit, toast with artisan bread and cheese before we did our first dive. We would come back to big, hearty breakfast which could consist of eggs, bacon, sausage, hash, browns and always a lot of fruit. There was always many Thai choices too. Because we were diving from a dinghy, there were two people on the deck and two deck hands helping us get safely into the boat. After the last dive, the crew rinsed all of our clothing and gear for us and left everything out to dry. I can see why three of the divers had come back multiple times.

My greatest recommendations for this boat The Phinisi, Thailand Master. I took a seven-day trip to Myanmar (apart from the fact that the week has gone by far too quickly😂) it has been an absolutely fantastic trip in all areas. I love the crew they are so good & the way they work together just makes it all play nice, security is top notch & the diving has been wonderful. 🐠 If/when I come back to Thailand I will take another trip with this boat.

The experience on the Phinisi (aka Thailand Master) was outstanding. The crew is very dedicated to safety and making sure all have a great trip. The dive director is so experienced and every briefing is done with original art work showing the dive site and going through what to expect. His knowledge of the dive sites and knowledge of all the many creatures comes with decades of work and a passion for his work. Marco ensures safety always comes first and is available for any question or issues. His team match his high standards. There is always a lot of food with options for all needs. Cabins are kept clean daily. Dives end with a cold or hot drink as soon as on board. The ship has great spaces to have a quiet time or time with others.

I went on the Phinisi (Thailand Master) and it was amazing. Specially the crew. The ship is very well equipped with the latest technology, air conditioning, water maker and even Internet while I was on board. The food was amazing. As vegan I can't complain about any meal. I can't recommend it enough.

Thailand Master, December 2025
Was on The Phinisi for a 10 day and 7 day trips. Was so impressed decided to book a 2nd trip right after initial one. The crew takes care of all the little details that make it a special trip. You don't worry about anything except eat (amazing food), dive (in beautiful spots), sleep ( in comfortable quarters), then repeat (up to 4 times a day)

Thailand Master, December 2025
The professionalism of the staff was outstanding, with Marco as Cruise Director always calm, competent, and in full control. All of the guides were extremely knowledgeable and consistently friendly. The boat itself is beautifully maintained and very charming. There are plenty of places to relax on board, both in the sun and in the shade. There is ample space for camera equipment, and in the lounge you can charge everything you need. The food was excellent, and what truly stands out is the incredible friendliness and helpfulness of the entire crew. I would choose the Thailand Master again at any time for a diving safari and can wholeheartedly recommend it without any reservations. Safety on board is also excellent.

Thailand Master, November 2025
My experience with Thailand Master Liveaboards aboard The Phinisi was truly outstanding. From the moment I stepped on board, everything felt professional, relaxed, and exceptionally well organized. The crew is incredibly friendly and always ready to help with anything you need. You can truly feel their passion and dedication to making your trip unforgettable. The boat itself is beautiful, featuring cozy and comfortable cabins and a lovely common living area where you can relax between dives. The large sundeck, half shaded and half sunny, is perfect for unwinding, enjoying the views, or simply taking a moment to yourself. The daily program was clear and well-structured, with thorough briefings so you always knew what to expect. Overall, this was without a doubt one of the best, if not the very best, liveaboard experiences I have ever had. Highly recommended for anyone seeking an exceptional diving adventure in Thailand.
So great! Had a blast! The crew was superb!

The whole trip was amazing. The whole crew really took care of us! The diving and the guides were amazing. The non stop food was off the charts! The cabins were clean and cleaned every day. Everyone helping us with our gear, filling our tanks and helping us get in and out of the boats we're all so nice and so helpful! It was so organized and we kept to the schedule that they put on the board every day. Marco, the cruise director, did a really great job on the whole trip! The whole trip was just amazing, and i hope to do it again some day!
