Fantastic !
My diving cruise with The Smiling Seahorse was absolutely fantastic from start to finish. Everything was extremely well organized and seamless, making the entire vacation completely stress-free and enjoyable. The crew was exceptional — professional, friendly, attentive, and always making sure everyone felt comfortable and safe. The food was amazing throughout the trip, with great variety and quality at every meal. The boat itself is excellent: very comfortable, well maintained, and thoughtfully designed for divers. The cabins are spacious and comfortable, and the common areas are very well organized, giving everyone plenty of space to relax between dives. What truly made the experience unforgettable was the incredible selection of dive spots. Every dive offered something special, with beautiful marine life, stunning coral reefs, and perfectly planned itineraries. Overall, this was a full enjoyment vacation and one of the best liveaboard experiences I’ve had. I highly recommend The Smiling Seahorse to anyone looking for a perfectly organized diving adventure with a fantastic crew and unforgettable diving.

Great week aboard the Smiling Seahorse
We spent a fantastic week aboard the Smiling Seahorse diving in Myanmar waters. It is an exclusive diving area, as there are no other dive boats around, although there are fishing boats. The life we found was mostly small: many moray eels, nudis, crabs... and also an ocean blanket! I especially liked that both the briefings and the diving were done with your guide in groups of a maximum of 4 people. The boat is comfortable; The cabins are small but with enough space. All the guides and crew did their best to make us enjoy ourselves and make us feel comfortable and safe. As an experience unlike any other life on board, we were given the option to try blackwater diving and I loved it!

Truly superb live aboard experience!
This was our first liveaboard diving trip so we have nothing to compare this with, however, I can honestly say that our expectations were more than exceeded in every respect. The Smiling Seahorse operation is superbly run and managed by its owner Franck, an extremely personable individual and diving enthusiast, who goes to great lengths to ensure that no detail of your stay onboard is overlooked. After being swiftly administered on arrival, Franck then delivered a welcome address to all passengers to explain how the boat functions, where everything was and then introduced all of his staff, from the captain and diving instructors to the chefs and general assistants. This was a great touch and showed how invested he is in his crew and for us to meet each and every one of the staff onboard. We were assigned our diving instructor (Mici) and dived with another couple of similar experience for the duration of the trip. Mici went to great lengths to put us at ease and explained every step of each dive we undertook but made absolutely clear that safety was her primary concern throughout. We undertook our PADI AOW qualification whilst diving and this was seamlessly integrated in to our diving programme. Some of the dives were quite challenging due to varying currents and invariably plans had to be changed underwater to reflect the conditions but at all times she had the whole group’s welfare and safety in mind. On all of the dives, the pace at which we covered the terrain was excellent and she was always attentive and keen to point out the abundant wildlife. The diving itself was varied, with Richelieu Rock providing the most spectacular array of sea life, from huge shoals of Trevally and Barracuda to amazing fan corals to name but a few. Visibility wasn’t always great and at times the currents were strong but we viewed this as positive learning and we always managed to see some incredible sights. The food onboard was simply outstanding! We are vegetarians and the chefs went to great lengths to ensure that we had an appropriate choice for each meal - the food was largely Thai inspired and was truly delicious. On one evening they even prepared a BBQ on the sun deck and this was preceded by some delicious rum cocktails, which went down very well! At various intervals Franck would make announcements to ensure all were informed or (as a keen underwater photographer) brief us on other aspects of diving (black water diving), which was offered as an additional activity. Despite the broad international makeup of the guests onboard, all were made to feel part of the ‘family’ and we made some great acquaintances during our trip. Overall, Franck’s outstanding leadership of the Smiling Seahorse and attention to detail is what made this trip so successful and enjoyable for all concerned. We would thoroughly recommend to anyone considering a live aboard and will undoubtedly be back again.

Highly recommended, exclusive services , friendly crew member, well organised diving.
In a summary, the trip was adventurous and amazing! We are pampered throughout the week and am amazed by the : Services Special mention on the services of the crews, they will try to fulfil the requests of customer with their best. They take note on each customer special needs and preferences very well. Owner Franck also provide very detailed briefing on every important matters and is always there to reach out. Diving The diving are well organised which you wont feel packed or waiting too long for you turn at the dive deck. We are divided into smaller dive groups at the ratio to dive guide at 4:1 and each group will take a rotation of sequence, which is fair and further enhances the overall diving experience. Dive guides are also very attentive and take safety precautions as priority. Furthermore, the boat and cabins are at the above average standard as this is not the luxury boat which also justify the price to be paid for.

Great experience
I can highly recommend the smiling seahorse. First and foremost, the entire crew is highly professional in all aspects of the operation. Briefings, operational procedures, tidinesses on the dive deck, execution of the dives and pick up back to the boat, all are done in a way to guarantee the utmost safety and comfort for the guests. I’ve been diving for more than 20 years and this has been one of the top operators I’ve had the pleasure to dive with. I can’t stress this enough: safe diving is the basis of a happy trip! Then there is the boat itself and the food: cabins were comfy, AC was very good (though it was also possible to sleep with the window open, which was very nice), the decks are set up really well, and the food was very good. Finally, and most importantly: the crew, from the deck hand to the dive leader, all were extremely friendly, approachable, and concerned with the safety, comfort and well-being of the guests. Thank you very much for making this a great trip!!

An amazing trip to uncharted waters, with a top notch boat and crew: high quality experience!
We enjoyed our trip with the Smiling Seahorse a lot. Our hope was to escape crowded dive sites in Thailand by embarking on a trip to the Mergui Archipeligo. This worked out great: we have seen no other divers throughout the entire trip. The diving was excellent, at healthy reefs with abundant marine life. The Smiling seahorse is a well maintained vessel that has been run by the same crew for many years. The whole team works together like a Swiss clock, delivering a care free experience of high quality and maximum fun. Attention to details is massive (e.g. reef friendly soap, a water branded bottle to replace glass as much as possible, Isotoner sachets, etc.). The group was quickly split up into groups of 4 divers & 1 dive guide. The groups take turns gearing up, so the dive deck is always calm and remains spacious. Each crew member knows what to do and delivers. The dive guides are very experienced, good company and a pleasure to dive with. Special thanks to James! By choosing to go to Myanmar, a country in troubled times, the organization adds an exiting edge to the trip, somewhat exclusive and special. Their contact with the Myanmar authorities is solid and the process went pretty smooth. One special feature on our trip was the Blackwater diving. What a great experience and eye opener! We came home truly enriched in our understanding of the ocean and stimulated in our ambitions to keep on exploring. Thanks Franck and crew!

Great liveaboard in a region few other boats venture into.
I just spent 8 days onboard the Smiling Seahorse in the Mergui Archipelago (Myanmar). Franck & Camille run a top-notch operation here. The new boat (2nd season in the water) was designed and built by them, and they've done a brilliant job with the layout and all the little details that are important for us divers. She is a beauty! The cabins are comfortable with plenty of power sockets and storage space, and with a silent AC unit and ensuite bathroom/toilet (I stayed in a Deluxe Cabin). The sundeck is huge, shaded and great to relax on, as well as the upper deck that has plenty of tables and sofas. The fridges and bar area are always stocked with drinks, snacks and freshly brewed coffee. The main deck has a really well designed and spacious dive deck, making it super comfortable to gear up before and after each dives. There's a really big photo room for all the camera gear, with lots of power sockets. That's also where the kitchen and chef is located. The food on the boat is really delicious, varied and plentiful. To top it all up, the way the diving and dive groups are organized is perfect: first, you can do 4 dives a day, every single day. This means a night dive every day! I've never had that on any other liveaboards. And the dive groups are always small: maximum 4 divers per guide. On this trip we were only 9 clients so most groups were 2 divers per guide, and every group usually jumps in the water with enough intervals so you don't even meet on the dive sites. I believe this really is a great set-up: relaxed, intimate, personalized diving. You feel like you have the whole ocean to yourself (very few other liveaboards come to these waters). Franck and the guides (all instructors) are all super nice, warm and fun to hang with, and they are also very experienced, serious and knowledgeable divers/guides. There's a great vibe on the boat. All the dives are the regular 50bar and/or 50-60minutes. The local crew members and tenders are all super cool and very good at their jobs: the gear is always well taken care of, the tanks and Nitrox blending always spot on, the boat always drops you at the right spot to find the dive site, and all the decks are always clean and tidy. Now the diving: first we were quite unlucky this week with some pretty bad viz (usually 5 to 10 meters). Second, even though the archipelago is a no-fishing zone, this is not enforced at all and there are a lot of small fishing boats everywhere and on all the dive sites (nets, cages, lines). Despite that, the quantity of life on most sites is pretty amazing: incredibly healthy and thriving corals, countless reef fish, big schools of barracudas, trevallies, Jacks, etc.. We saw a lot of critters (nudibranchs, shrimps, crabs, seahorses....) as well as quite a lot of massive marble rays and stingrays. The topography at most sites we went to is breathtaking: dramatic pinnacles and walls, gorgeous coral gardens, boulder fields, swim-throughs and small caves. I can only imagine how incredible these sites would be with a better viz (that you do get!). Probably due to the combined bad viz and over-fishing, we didn't see many sharks or turtles, and no mantas (but they were spotted on multiple dives the week before us). But still, the diving was great and I can only recommend the Smiling Seahorse and the Mergui Archipelago! I will be back!

Well organized boat, fantastic diving, tasty food
We did all 25 dives on this trip and loved them all. The variety was wonderful - from nudis to cobias, from swim throughs and caverns to beautiful healthy reefs, and a fascinating intro to blackwater diving. Our guide James was our favorite dive guide ever - hilarious and so knowledgeable. This boat is organized extremely well, with every detail thought through for a fantastic diving experience (great camera room, four dives per day). The food was always delicious, and the barbecue party on the last night was super fun. Our only small wishes would have been better weather (less rain and rough seas) and an air-conditioned communal area (the dining area is open to the outside). Very competently run and joyful diving holiday!

"Great Diving, Great Crew – A No-Frills Liveaboard That Delivers"
The dive safari with The Smiling Seahorse was a fantastic experience, offering great value for money without unnecessary frills. If you're looking for a well-organized, professional, and welcoming liveaboard in the Andaman Sea, this is a great choice. The dive team—James, Velika, Lady, and Simon—are exceptional. Not only do they know the dive sites inside out, but they also have a deep passion for the craft, ensuring each dive is both safe and memorable. The crew on board is equally impressive, keeping everything running smoothly, maintaining the gear, and assisting with effortless water entries and exits. The boat itself provides everything you need for a successful dive safari. There’s a dedicated camera station with compressed air and ample power outlets for charging equipment. Between dives, you’ll find plenty of space to relax in the shade—or stay dry if the weather turns. While the accommodations and amenities are simple and practical rather than luxurious, they are more than sufficient for a comfortable trip. Overall, The Smiling Seahorse delivers an excellent diving experience at a fair price, making it a solid choice for divers who prioritize top-notch guiding and seamless logistics over high-end amenities. If you're after incredible diving in the Andaman Sea without breaking the bank, this is a great option.
