Fantastic dive boat and beautiful diving
This was an excellent Liveaboard trip. The Similan Islands were beautiful, with lots of varied dive sites and marine life. Richelieu Rock was an absolute highlight - so colourful, so much life. The staff were so good - very friendly and they really took great care of us. The food was amazing - so much variety and every dish was delicious. Airconditioning in the rooms was great, and bean bags and hammock on the top deck so comfy. I would highly recommend this trip.

Emergency handled well
I could not have been happier with the crew. Only were they very attentive and preparing and ending a dive, making life very easy, your Dive master Rhonnie is awesome. I had a Dive emergency at depth with a complete blowout of my first stage. Ronnie immediately responded and offered aid. Thankfully, we calmly handle the situation and safely ascended. A huge shout out to Ronnie. Other than that, it was an awesome trip with awesome people

I'm a divemaster using a liveaboard for the first time.It's a liveaboard that has just been made, so the facilities are kept clean overall.It is clean with no breaks, rusts or dust in the corners, and no smell in the bathroom, so it is pleasant.The dive leader, Mark, is very enthusiastic about the daily morning briefing.The food is mainly Thai food, but it is also good for Korean tastes.Had a fantastic diving experience on such a nice liveaboard that I plan to visit again with the Korean dive team next year.

An Unforgettable Liveaboard Diving Experience!
This liveaboard trip was nothing short of extraordinary—hands down one of the best diving experiences of my life! From the moment we stepped on board, everything was flawlessly organized, welcoming, and professional. The crew were absolutely incredible: knowledgeable, attentive, and genuinely passionate about diving and marine life. They went above and beyond every single day to make sure everyone felt safe, comfortable, and excited for each dive. The dive guides were top-tier—expert briefings, perfect site selection, and an amazing ability to spot even the smallest and rarest creatures underwater. The diving itself was simply spectacular. Crystal-clear water, pristine reefs, big pelagics, colorful macro life—every dive felt like a highlight. The variety of dive sites kept things exciting, and the schedules were perfectly balanced to maximize bottom time without ever feeling rushed or exhausting. Life on board was just as impressive. The boat was spacious, clean, and very comfortable, with cozy cabins and plenty of room to relax between dives. And the food—wow! Delicious, fresh, and plentiful, with something to look forward to after every dive. What really made this trip special was the atmosphere. It felt like one big diving family by the end—great vibes, lots of laughter, and unforgettable shared experiences both above and below the surface. If you’re considering a liveaboard diving trip, stop searching—this is the one. I would 100% book again without hesitation and recommend it to anyone looking for world-class diving, outstanding service, and memories that will last a lifetime. 🌊🐠🤿

Experience the diving utopia in Seatopia
Just came back from a 5D4N trip on Seatopia Liveaboard to the Similan Islands, and honestly, it was amazing! There were around 20 of us onboard, and the vibe was super chill and fun the whole time. The crew was young, friendly, and full of energy — always joking around but also super professional. Our dive guide, Game, gave really clear and detailed dive briefings, so every dive felt safe and well-prepared. One special moment was when we spotted a fishing net tangled around some coral. Everyone stopped and helped remove it together — it felt great to do something meaningful for the ocean. The food was great and varied, and we could grab soft drinks anytime. The boat was super clean and everything worked perfectly, which made the whole trip extra comfortable. Couldn’t have asked for a better liveaboard experience. Big thanks to the Seatopia team — can’t wait to dive with you guys again!

New boat with everything you need + good food, dive crew, boat crew and diving!
This has been my third liveaboard in total and based on those experiences, I can recommend Seatopia as a liveaboard operator. The communication was clear and detailed. They created a WhatsApp-Group with all guests before and sent detailed information on the process and upcoming fees (e.g. national park, nitrox, rental equipment, customary tips, ...), so you can prepare yourself. The pick-up was smooth and the boat and dive briefings extensive, supported by pictures on a TV screen. The boat itself is almost brand new, we were trip nr. 39. I liked that all the cabins were above sea-level, which makes sleeping more peaceful for me. The shared bathrooms for the twin and bunk bed cabins are on the main deck downstairs and offer hot/warm water and soap/shampoo dispensers, which was really nice. They produce their own freshwater on board, that's really convenient. Food: I enjoyed the food very much. It was diverse throughout the trip and offered a good mix of western and classic thai dishes (Tom Yum, Tom Kha Gai, Banana Samosas, Papaya Salad, ...). There are always fresh fruits (bananas, clementines), cookies, coffee, cocoa, juice, softdrinks, milk and tea available. The only thing that needs to be paid extra is beer and capsule coffee. And they provide electrolytes and encourage you to hydrate. Before and after every dive the cooking staff would come with a tray with a small cup of hot beverages for you to hydrate, which was lovely. Diving: The boat crew was always ready to help you with your gear and analyzing the Nitrox tanks. They hang the wetsuits after every dive. My group was well matched with the skills and my dive guide Kat was friendly and spotted lots of small animals for me (ornate ghostpipe fish, seahorses, pipefish, nudibranches, ...). The dive sites in Similan were quite diverse and a mix of rocky underwater landscapes and pinnacles with pretty coral reefs, and lots of glass fish! There are fish ID books on board, so you can identify whatever you have seen underwater. The six dive groups (4 guests + dive guides) were managed well and fair and it never felt crowded on the dive deck. Every evening was also some kind of funny quiz where you could participate and win a Seatopia T-Shirt, those were quite fun and engaging. Offboarding and drop-off was smooth too. Fellow guests: Nothing the dive operator can do about, but please (if you read this as potential future fellow diver) don't go on the boat when you have a fresh cold and are coughing and sneezing around. You might save your trip, but ruin it for other people when you infect them. I guess that's about it. Happy to have chosen them!

Incredible Trip
What an amazing trip, i wouldn't know where to begin! My partner and I double booked this liveaboard due to the already-fantastic reviews, yet our experience has surpassed our expectations already. The crew are super friendly and always found a way to safely facilitate our dives, despite the challenging weather conditions (strong currents, high waves, heavy rain at times). We were split into smaller groups of 4 divers with our own dive guide (Mik) who was wonderful: very good spotter, always friendly and understanding of my partner's sea-sickness. The cabins and beds were suprisingly comfortable, which in our experience from 4 previous liveaboards is a real luxery. The quality of diving was superb: very vibrant coral reefs packed with life, from tiny nudibranch to towering schools of trevali, barracudas and occasionally groups of tuna. We even saw several large sea snakes passing through, as well as multiple types of morays - the value for money on this trip was by far one of the highlights. The food served was flawless and was an eagerly anticipated part of the day from everyone onboard: great variety of pork, chicken and seafood dishes, with veggie options also available. We could not have wished for a better first experience diving Thailand and would recommebd this to everyone looking to dive this wonderful country, so thank you so much Seatopia!!

Absolute Gem for exploring the South Andaman Sea
The crew's dedication was exceptional - they went above and beyond to ensure everyone felt welcome, actively listening to our preferences and accommodating every need, from dietary requirements to providing medicine when needed. The dive operations were impressively professional. Briefings were comprehensive with meticulous attention to detail, and the safety culture on board was exemplary - something that can't be taken for granted on liveaboards. As a sidemount diver using twin tanks, I particularly appreciated their flexibility and support with my uncommon configuration. The crew assisted at every step, handling my second tank and making water entries and exits seamless. The food deserves special mention - every single meal was outstanding. I genuinely looked forward to each sitting, and there wasn't a single dish I didn't enjoy. The boat itself is brand new and pristine, featuring comfortable cabins, a relaxing sun deck, large tables at the stern, and a spacious dive deck that never felt cramped. They offered a reasonably priced nitrox course on board, which I'd strongly recommend for anyone planning to make the most of the four daily dives. The dive sites showcased fantastic variety - from dramatic walls and cliffs to shallow coral gardens and deeper reefs. Adventure seekers will love the numerous swim-throughs, and the large wreck dive was particularly memorable. The night dive added another dimension to the experience. The guides had an excellent eye for marine life, ensuring every dive had its highlights. My personal favorite was encountering leopard sharks. Overall, Seatopia delivered an outstanding liveaboard experience with attention to detail that sets them apart.

Good option for diving in Similan and Richelieu Rock
We have enjoyed these 4 intense days of diving very much. Richelieu Rock is very worthwhile, other points of Similan are not so spectacular, but we have enjoyed it anyway. Dive groups are a maximum of 4 divers per guide. Our guide Peem, the best! He has tried to find us all the possible animals to photograph! The food is very tasty every day, sometimes too spicy for those of us who are not so used to it, but we have eaten very well. In addition, snacks and fruit are available all day. They also have a good first aid kit available for any emergency. They do not provide towels when getting out of the water, but it was not a problem as I could directly go to the cabin. When we go in and out of the water we have always been given water or tea. The assessment in general is very good; Perhaps we have missed a safety breafing of the ship when embarking. The dives are very frequent, for me perfect! But if you are looking for a more relaxed diving plan, this is not your boat.

Could live on the boat if money and time werent an issue.
Wowsa, what and experience if you are looking for a high class service without having to sell an organ this is it. The boat is new, clean and well laid out and only 2 to a cabin which are also of a decent size. Thai owned and run and they do not disappoint from the moment you have booked, lots of communication to make things as easy as possible for you whilst also accommodating to your needs. The crew (Captain, engineer, deckhands, cooks) were phenomenal always smiling, super helpful and willing to have a laugh. The food that the chef and assistant can turn out in a small kitchen is delicious and plentiful, you will never go hungry and the warm drink as you get back on deck after every dive was a luxury that I didn't know I needed. The dive instructors (Mark, Neil, Dan, Kat, Arm and Game) are fantastic always willing to have a chat and answer any of the 1000 questions you might have about diving, fish id, Thai customs, culture or anything else you can think of. I take my hat off to the owners for putting together a phenomenal crew that take pride in their work, delivering an outstanding service. I dare say we will be back. If you want an exceptional diving experience without breaking the bank you have found it here.
