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.

Liveaboard heaven!
MV Gentle Giant was simply amazing. This was my first liveaboard dive boat and I couldn't have been happier. Let's start with what is most important, the diving. Anyone looking into diving in Phuket knows Similan Islands to the northwest and Phi Phi Islands to the Southwest. This boat, in one trip, covers it all. We did a 5 day trip and dove 18 times. We went everywhere that Thailand has to offer and saw more fish, coral, reefs, sharks, octopus and other amazing creatures than you could hope for. You set up your gear (or they provide if necessary) on day 1 and it never moves. They refill your tank between each dive so all you have to do is put on your gear and jump in the water. They even have people on deck to defog your mask, help you put on or take off your fins and hand you any gear that you want (pokers, lights, cameras, etc...) Now, the food. My expectations were low and was I ever surprised. The chef was amazing. We have an assortment of Thai and international foods. Hot pots, steaks, seafood, eggs, rice and just about anything you could imagine. Have a request, they can do it. Finally, the crew. Travis was the dive master assigned to my group of 4 and he was amazing. He could help you with your gear, show you some amazing creatures and was just great to hang around with. Overall, there were 5 dive masters for 20 divers, so each dive master had a group of 4 each time. This love diver to dive master ratio was spectacular. Another unexpected treat. As a diver for over 20 years who has been around the world, all I can say is, if you are looking for a live-aboard this is the boat for you.

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!

It's too hard to think of just three! I would say; the itinerary, the people and the ease of the whole week.

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.

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 :)

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!

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.

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.

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.
