The spacious dive deck at the back of the boat allows ample room for kitting up and gear storage and a dedicated photography room.

Sail the Andaman Sea in a friendly atmosphere
My wife and I just spend an amazing week living aboard The Smiling Seahorse which took us through the many renown diving spots Thailand has to offer. The past 7 days, we sailed the Andaman Sea, stopping at busy Richelieu Rock by the Mu Ko Surin National Park and exploring the wonders of Ko Tachai and Ko Bon. We were amazed at the beauty of Breakfast Bend (3 trees), the imposing Elephant Rock (Hin Pusa) and Shark Fin Reef (Hin Phae) dive sites off the coast of Mu Ko Similan National Park. We were greeted by superb Oceanic Mantas at Red Rock (Hin Daeng), Purple Rock (Hin Muang) right in the Strait of Malacca and gasped at the grandeur of Cathedral (Koh Haa Yao). Last but not least, Ko Li Pe delivered schools of Fusiliers, Trevalis and Small Tooth Emperors reigning over the rest of the innumerable schools of fishes at Stonehenge and 8 Miles Rock (Hin Paad Mile). The crew on board was the friendliest and always helpful, accommodating my wife’s (many) food allergies with kindness. Speaking of the food, the chefs on board are incredible and you are in for a treat after each dives (my favorite being the post-morning dive breakfast). Our cabin (number 1) was spacious with a large bed and ample space to organize and store our luggages away. The bathroom was clean and perfect for a week on board. The entire dive masters crew was always professional, taking the time to go over the dive plan, answering any concerns and helping locate and identify the many hidden wonders discovered during each dive. We highly recommend signing up for the black water dive if this is something you have never done as Franck (the owner) is an amazing photograph and will lead you through a new way to discover our animal kingdom. Kudos to Franck and his team for organizing everything in a seamless fashion getting on and off the boat and everything in between. Thank you for having us, we’re looking forward to discovering Burma in a future adventure!

Amazing Time on the Smiling Seahorse!
This was our first liveaboard experience and we were blown away by the Smiling Seahorse and the Similan Islands/Richilieu Rock itinerary. The dive guides were very professional (safety first) and helpful. We loved it and highly recommend boat owner and dive photographer Frank and his team for your next diving excursion in Thailand or Burma.

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.

Best way to go diving in the Mergui Archipelago and the Burma Banks , hands down.
The trip was logistically setup in a very clever way. Each and every day there were highlights and surprises to be discovered. I experienced my first two Blackdives after almost 3 decades of recreational diving and it was mind-blowing. Frank and his team work very hard let the clients enjoy the cruise, and, last but not least , the security was considered paramount every time.

Amazing experience.
We booked the photography expedition in the Similan National Park with the Smiling Seahorse. The boat is a 3 deck dive boat with functional cabins, a mess hall, and a perfect setup room for underwater photography and general rec diving. The boat owner and leader Frank is also a photographer. He is a super friendly and fun person to be around. He was very engaged in the day-to-day activities, and his excitement about the diving and photo opportunities was contagious. He also went out of his way to give us tips about underwater photography, which were greatly appreciated. He is an amazing photographer and his presentations were engaging and informative. Our guide, James, was equally top notch, and easily one of the best dive guides we’ve had in our diving history. He was safety conscious, highly skilled, and we learned so much from him about the reef sites we were visiting, including the sea life, and tips for safe diving in general. The supporting crew was equally amazing, ensuring tank fills and gear were setup, and the meals were good. Everything was well planned out so it never felt too crowded onboard despite full capacity. What you don’t easily see is all the work the crew is doing behind the scenes to make the liveaboard the most enjoyable experience. The dive sites themselves were fantastic, with healthy reefs, corals and fish, and the dive operation is very conscious of protecting the reef. The blackwater dive was incredible and unique , and each dive site provided great variety. This was one of the best diving trips I’ve done, hands down, and the crew and boat deserve the highest praise. We will be back soon!

"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.

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!

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.
