Five stars are not enough! This was an exceptional trip with a brilliant crew, what a wonderful week.
We were upgraded from Gentle Giant to the Raga; this was an unexpected bonus as the boat was excellent. Well appointed, comfortable cabins etc. The food was restaurant quality, every day the meals and snacks were different, from coconut smoothies to ice cream cones! The crew couldn’t have been more helpful, from the boat drivers to the kitchen staff & guides, they were all friendly , attentive and eager to help. Nothing seemed to faze them and nothing was too much trouble. This is undoubtedly the best liveaboard I have been on - well done Smile Dolphin, we will definitely be using you again.

Varied beautiful diving
With great dives in the north and south in the Andaman Sea, this trip offered varied dives from beautiful coral reefs to always beautiful schools of fish and highlights such as leopard sharks and seahorses. Despite some poor visibility, the dives were relaxed and quite beautiful.

Highly recommended, especially the Southern trip!
A wonderful experience! The boat feels spacious and the crew takes really good care of you. It was the first time for me to do the Southern dive sites (most boats go to Similan and Surin islands). Visbility is a little bit less but wth A LOT of sea horses definitely worth visiting. I want to go again :)

Much more values than I Expected
It was very relaxing to see scenery from the top of the deck. Delicious food was served 4 to 5 times a day, and freshly cooked with a sense of Thai.Crews were very helpful when putting on and taking off the equipment.Guests and crew landed on the Phi Phi Island and watched a fire show after diving at night, which was unexpected. Two whales showed up to the boat.

A large school of fish, zebra shark at Hin Bida, several kinds of exotic fish unseen before.

Best week ever!
This was my first liveaboard experience and I can honestly now say that I am a convert. It is THE best way to dive - 4 dives in one day?! Yes please! Everything about the week was wonderful, from the dives and seeing things from turtles to sharks, and swimming through incredible caves, to the attentiveness of the dive support team and the briefings with our guides, to the wonderful food. So glad I was able to make it over to Thailand to enjoy this incredible experience.

Simple but beautiful boat
We spent a really nice time on the Gentle Giant. The boat is simple but equipped with everything you need. Each cabin has hot water showers, air conditioning and windows. The crew is very nice and there are 4 at least 4 meals a day. Snacks are available around the clock. We enjoyed the time very much and can recommend the liveaboard to everyone.

Moray Eel vs.Triggerfish
I booked a tour with Gentle Giant and MV Raga to the Similan Islands. Both tours were fantastic. Great staff and lots of sea life to see. The dive sites are varied and, for me, among the most beautiful ever. Special thanks to the guides, Sasha, Spice, and Freshy. Thanks to them, I got to see lots of cool things that I would otherwise have missed. The whole staff does a great job, and on every tour, the friendly owner stops by to ask if everyone is satisfied.

Best liveaboard experience!
We did 10 dives in 3 days to the surrounding islands of Phuket, and it was excellent! We saw 3 shipwrecks, lots of coral, sharks, eels, rays, other animals and millions of fish.. very satisfying! The accommodations were nice and the food was beyond excellent. All the guides were very nice and the boat boys were amazing in helping us get ready, and on/off the boat for every dive. An incredible deal for the price!

A fantastic dive tour of the Andaman Sea islands and dive sites.
I selected Gentle Giant because of its itinerary. Most boats either dive the northern or the southern Andaman Sea. In the same trip, Gentle Giant visits all the most important and beautiful dive sites on the Indian Ocean coast of Thailand, both in the north and south. From the Richelieu Rocks teeming with life, through the fifty-plus meter visibility of the Similian Islands, to the sharks of Koh Phi Phi, our guides, fluent in both English and Mandarin, put us on all the best spots! The diving was amazing! The staff and crew were super friendly and helpful, and the food was fresh, savory, and abundant, with Thai, Chinese and Western selections. I look forward to diving again with Gentle Giant in the future.

Great experience! Would 100% do again
My husband and I were on the Gentle Giant during Christmas week. We were a bit apprehensive at first as it was our first liveaboard experience and there were not many reviews for this boat in particular, but we were worried for nothing. We really enjoyed our five days onboard and this was the favorite part of our 2 week vacation in Phuket/Krabi. The diving was super, we did 3-4 dives a day. Dive are 50 min and they feed you lots of delicious authentic Thai food before and after each dive. We saw all sorts of pufferfish, porcupine fish, batfish, huge group of thousands of yellow snappers, tuna, groupers, giant trevally, a huge swarm of barracuda (must have been at least a few hundred, which was the highlight of the trip), lots of giant morays, other morays, sea stars, sea cucumbers, nudibranches, a freaky walking featherstar, and tons more. Our only regret is we did not see mantas or whale sharks even with multiple dives at Richilieu, Koh Bon, and Hin Deang/Hin Muang. Boat crew was super helpful in getting your gear ready, switching tanks, helping you on and off the boat, it was truly full service diving. We will be back and dive again with Gai and his team!

North is the best
First of all I’d like to thank our amazing dive guide Mint for her professionalism and commitment, she kept us safe and we had a very good time underwater thanks to her, then I’d like to thank the kitchen chef, food was amazing, and the boat crew for all the hard work. As negative aspects of our trip I noticed the following: - very noisy boat, made it very difficult to sleep at night - ⁠very reductive briefings pre-dive, missing information about currents, visibility and in general the risks we could face underwater - ⁠the itinerary was mentioning to visit the best sites, but only the dives we did in the north were beautiful, going south the chosen sites had always little coral, little fish, bad visibility - ⁠uncomfortable common areas and a living room that was acting as bedroom for the dive guides, so could not really be used much as common space, the top of the boat had little cover from the sun, and just some mats with no pillows, the dining area was not the best place to relax in between dives as the space was reduced by the dining tables and to sit you just had benches. - ⁠the boarding part in and out was never comfortable as we had to go through another boat or use the dinghy - ⁠the dive time was always ridiculously short: 50min max day and 40min night, and we were not informed about it before paying for 15L tanks As positive aspects I noticed: - our dive guide Mint, thanks again Mint you really did an amazing job - ⁠shower with hot water - ⁠the food was amazing

I was looking for an adventure, but instead I found a family that loves diving as much as I do.
Everyone on the crew was great and made this experience very special. Great group of divers to share this trip with. I felt like I have known them for a long time. Astounding rock formations at Elephant Head. The huge amount of marine life at Richelieu, that is impossible to describe. Must see for yourself. The beauty of Similan. Special thank you to Fei. You will always have my respect and admiration.
