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.

Another vote for the Smiling Seahorse - it's a very good boat. Purpose built for serious diving, the thought and care put into it by its owner and crew really shows. Everything you need is available, easy to access, well maintained and functional, without anything extraneous or funky.  There is a devotion to diving, to underwater photography, to the marine life, to the history and natural history of the Similan Islands and Burma, to the guest experience and developing our skills. Our group did the week-long South to North Andaman Sea trip in January 2026, and each day was better than the one before. The diving is exceptional, with healthy corals and masses and masses of fish, even before we got to the climax of Richelieu Rock. They include an black water dive on each trip, a truly unique opportunity.

We received tremendous support from the dive guides and the crew alike, who gracefully and respectfully accommodated everyone's needs.  Even the little things - one of the deck crew noticed that the little strap connecting the dust cap to my regulator was close to breaking off and offered to repair it. He did a beautiful job and I'll be reminded of his generosity and kindness each time I dive that reg. Our guide, James, has years of experience, like many masters, conveyed his knowledge with simplicity and clarity (and humor - whew!). I became a better diver following his example. I keep remembering the happy anticipation of standing at the stern, all kitted up, waiting for the captain's signal to jump. Next trip - Burma.

The cabins are simple and comfortable,  although you may want to bring a pad if you're not a fan of firm beds. A/C and hot water in each cabin - all good.

Everyone in our group, from the experts with many thousands of dives to the recently certified, to a couple of non-diving spouses, loved the Smiling Seahorse!

We had an amazing time on the Smiling Seahorse liveaboard in Thailand. Everything was well organized, relaxed, and very professional.

Our dive guide Julien was fantastic. He showed us beautiful dive sites and even pointed out tiny nudibranchs we would never have seen ourselves. His eye for detail made every dive special.

The food was excellent, and the crew was incredibly friendly and helpful, especially when assisting with dive gear.

Overall, a wonderful experience – It was our 2nd trip and we will definitely come again!

An Unforgettable Week Underwater!
I just wrapped up a phenomenal week-long liveaboard trip in the Similan Islands with The Smiling Seahorse team, and I cannot recommend them enough. The dives were absolutely gorgeous, but what really set the experience apart was Julian’s amazing spotting skills—he has an incredible eye and made sure we didn't miss a thing.
The entire crew was attentive, professional, and always right there to assist with all of our needs, making the whole week completely seamless. On top of the world-class diving, the food was fantastic. Everything was incredibly tasty, and they offered a great variety of dishes that really hit the spot after a long day in the water. Five stars across the board—if you're looking for a top-tier liveaboard operation, this is the team to go with!

I went for a 9 day dive safari in Myanmar, the mergui archipelago, with the smiling seahorse. One of the unique experiences I had. My first (and second and third) Blackwater dive, dives I will never forget. The staff are wonderful, the dive guides are amazing, they actually care and put in a lot of extra effort and the ship crew were helpful and nice. I dove with Julian, the dive master, who I would dive with anywhere anytime, and we enjoyed the presence of camille, the owner, who lit up the place with her positive energies. I've been on fancier boats, but I enjoyed this one much better.

Safe, clean, friendly staff always willing to help, easy on and off the boat, good dive sites. Guides are awesome. The dive crew very accommodating.  Nice camera room. Keep the same tank entire trip. Some sites we went in small groups in a dingy. The return the dingy would slowly pull you back. Thankful we did nit have to struggle getting back in the dingy Some times we would just float back to the boat. We were divided  into groups so everyone wasn’t getting ready at the same time. Plenty of food and snacks.  Only complaint is the chairs and beds are hard as cement. Compared to the good stuff that was nothing.  I would for sure go again.

We did seven days on the Smiling Seahorse level over. The crew the boat everything was amazing. The divers did 20+ dives and as a snooker we did four snorkels, which was totally unexpected and so delightful. Took us to some of the best Dive spots in the world and the pictures proved that’s true. The food on board was over the top!!  I would recommend this trip to anybody around the world!

I just returned from a week-long liveaboard with the club, and the experience was simply outstanding. The entire team demonstrated high professionalism throughout, with in-depth safety briefings and modern, well-maintained equipment.
A special thanks to our amazing dive guides: James, Velika, Katie, and Mint. Each of them brought great energy and uncompromising expertise. Thanks to them, we felt in safe hands during every dive, and they knew exactly how to lead us to the most beautiful spots in the pristine sites we visited.
The boat was very comfortable, and the excellent food between dives rounded out the experience perfectly. This is without a doubt a top-tier diving club, and I highly recommend it to anyone looking for a week of peace and world-class diving!"

An outstanding liveaboard experience from start to finish. The hospitality on The Smiling Seahorse is truly exceptional — warm, attentive, and genuine, making you feel welcome and taken care of at every moment.
The dive sites were beautiful and well chosen, offering a great variety and excellent conditions. Each dive felt thoughtfully planned to maximize both safety and enjoyment.
What really sets this liveaboard apart is the extraordinary professionalism of the crew and dive instructors. Their experience, calm approach, and attention to detail were evident throughout the trip. Briefings were clear and thorough, underwater guidance was excellent, and safety was always the top priority — without ever taking away from the fun.
Highly recommended for anyone looking for high-quality diving combined with top-level service and professionalism. I would gladly dive with them again.
