Couldn’t have had a better first liveaboard!
My first liveaboard experience and may be the best one I will ever have. Well organized diving schedule. Funny and nice staffs. Handsome and pretty diving guides. One of them is Miss Thai, can you imagine? Love the food and may have eaten too much before diving lol. Loved the quizzes time and everyone is so obsessed with winning lmao. Met divers from all over the world and definitely a lifetime experience!

True seatopia!
We had an incredible liveaboard experience with Seatopia. From the moment we boarded to the moment we sadly departed, we were taken excellent care of. Fantastic service and assistance throughout, with attention to the details and small and kind extra gestures. Felt welcomed and part of a community on board. Delicious food. Great locations and entry and exits from dives. Great instruction and fish ID’s! Excitement all around the dives. Great awareness of marine life and need to keep it protected. The crew and divemasters were a great team together!

Going for it again!
I’ve had the most detailed and thorough dive briefing I’ve ever experienced on a riverboard. Safety was emphasized repeatedly, and everything from photography tips to what to expect during the dive was explained in great detail. Mark made sure everyone stayed within their NDL safely. The crew is incredibly attentive—no matter how busy they are, they never forget what you say and always come back with a thoughtful response. The food was good, and there were so many young people from all over the world, which made the experience even more enjoyable. The diving deck can get a little crowded, but as long as you follow your turn and stay mindful, it all works out surprisingly well—everything is actually very well organized, so it’s not a problem at all.

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!!

Dive crew are excellent and experienced giving good briefings and keeping track of everyone effectively underwater. Food was just okay, but the diving and crew more than made up for it. Incredible value and great critters on every dive.

Great experience.
Overall, I really enjoyed the trip. The crew was great! Very helpful getting into gear, making sure I had my separate meal (seafood allergy), and generally being courteous and fun. My dive guide Arm was one of the best guides I’ve had. He’s confident, leads the dives well, but is respectful of the skill of the divers and doesn’t mind micromanage the dive. He shared the videos he took on the dive at the end which was really great. Seatopia is a new boat so it’s very clean and well managed. The food was great. Overall- if you are wanting to dive Similan Islands in Thailand, I highly recommend.

Highest value for money with a lot of fun. We purely loved it! New boat, new equipment and very much fun to dive with our excellent dive guide Ronny. The boat crew was always ready to help, to fix issue and to help in all aspects. The what’s app group helped a lot to arrange the transfers and the information sharing upfront. Well organized. The food was very delicious for veg and non vegetarian. We fully recommend Seatopia. Go for Seatopia! No doubt! Always ready to dive again Seatopia!!!

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.

The dive guides and the crew were all super nice and friendly. The food was excellent. The boat is a bit cramped with 24 guests but the organization made it easy to gear up and dive.

Amazing Liveboard Trip
This was a fantastically organized liveaboard, everything in the trip was organized perfectly. The boat is pretty new so living on it was great. The diving was great around the south andaman sea with a great variety of sites and conditions to explore. The dive guides were brilliant in taking us to all the sites and also telling us on different things to look out for. Along with that the small ratio of dive guide to group was also a big plus. Beyond diving the food made was fantastic by the chefs. After each dive we had a delicious meal waiting for us to eat. The boat crew were fantastic with everything from helping us with getting geared up to getting off and back on the boat safely. All in all an amazing trip by the seatopia team.

Second trip even topped the first!!
Just completed our second trip with these guys from our back-to-back booking and this time was somehow even better than the first. This time we booked the ensuite double cabin and it was extremely comfortable with a hot water shower, large double bed and more storage space than the bunk cabins. We were guided by the diving lead (Golf) this time and he was superb: amazing spotter, very charasmatic and pleasant to dive with. Due to the calmer waters, we were able to do a few different dive sites and managed to spend a full day on Richelieu Rock - including a sunset dive. There was an abundance of marine life to be observed. This trip had something for everyone: staggering tornados of trevali's, large schools of barracuda, dogtooth tuna, blacktip reef sharks for the pelagic lovers - to tiny blue dragon nudibranch, cuttlefish, octopus, stingrays, boxfish and lots of morays for the macro/casual divers. The food remains an incredible, authentic experience in itself and there were some new changes in the menu from our first trip to keep things interesting. The crew are always tentative and provide excellent service, we really could not recommend a better liveaboard experience than this. Whether this is your first liveaboard experience, your 100th or a back-to-back booking, the crew and dive leaders will ensure you will not forget this trip. We are already interested in booking a 3rd trip to explore the Southern islands!!

Relaxed diving on a friendly, well equipped boat. 10/10!
A really well organized trip with incredible diving, the best food I have had on a liveaboard and a friendly and professional team that made the diving seamless. Our double cabin was simple but spacious and equipped with everything you could need. Or felt really relaxed for a liveaboard and while the ‘dive, eat, sleep, repeat’ formula was true, the pace felt relaxed and there was plenty of time to enjoy the sun deck and have a bit of down time. The dive sites did not disappoint with plenty to see big and small. A great trip!

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.
