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.

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.

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.

Amazing crew & lots of food

The crew were amazing, what a wonderful bunch of individuals that work exceptionally hard to make sure your needs are met. There were a lot of dive sites visited some were magical, it was a a shame to see so much damage on some, especially koh bon…. Not the boats fault, was just saddening. The crew are a happy bunch that couldn’t do more for you, however at times more energy could be injected into the the dive briefings. The boat was what could be expected at the price point, I would say if you value a good night sleep the beds on this vessel might leave you wanting.
