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!

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 :)

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.

Much better than I expected
This is the cheapest but the best liveaboard I’ve ever had. The crew members are friendly and professional, having the right attitude to serve the customers. They love what they are doing which I can tell from their smiles. My guide TK is smart and well paced. She’s quite familiar the underwater environment and even knows when the Trevallies start hunting. I think she had shown us the best of that part of ocean. Food was of good quality and really suits my taste. The room is a little bit small but clean. We saw GTs, barracuda tornado, snappers, crocodile fish and a variety of marine lives. The corals at the Tachai reef are gorgeous! The trip is excellent!

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 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.

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.

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.

Fabulous people, incredible diving and just a wonderful week!
My partner and I had an incredible week onboard the Gentle Giant. Firstly, everything was very well organised so we were kept well informed of the daily plans. All the crew were excellent - the guides, the chef, stewardess, the boat guys and captain. Everyone was helpful, friendly and really made our stay fun, enjoyable and just really easy. The itinerary was well balanced and we felt that we really made the most of our time on the trip. Our guide, Gai, was very knowledgable and knew the sites well, he made sure we were kept away from larger groups underwater and pointed things out that we wanted to see. Overall, an excellent time - would recommend!

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

ok
Some dive sites were amazing, while others were disappointing and felt like dives done only to increase the dive count. Our cabin was not cleaned for the entire week. We only discovered at the end of the trip that housekeeping had to be requested, which was not explained during the initial briefing. On previous liveaboards in other countries, cabins were cleaned twice a day without having to ask. The food was excellent. I observed some very concerning environmental practices by members of the boat staff. There were no non-diving activities. We were told we had to choose between visiting Phi Phi Island or doing more dives, but we were then taken to several dive sites with very little marine life due to overfishing, which the crew appeared to be aware of. 15 tank and Nitrox ridiculously expensive.

Amazing…couldn’t of asked for a better trip
Cannot thank our crew and the staff members on board enough. They made our short stay unforgettable. Everyone so friendly, professional and made us feel like part of the family. Every meal was incredible! And there was plenty of! Our dive guide was amazing and we were lucky enough to see elusive guitar sharks…truly incredible. The rooms were simple but comfortable. Each day we had a dive briefing, a very clear plan of action so we knew what to expect. Truly cannot recommend enough and we rave about the Gentle Giant to everyone who asks about our Thailand honeymoon.
