Big to small - you will see it all!

Diving and snorkeling with gentle giants was an absolute pleasure. Guides new where to find the rare macro life (great for photographers).

It's about the diving!

I look to reviews to help me make satisfactory choices and avoid disappointment (and thus bad reviews). My review will, therefore, reflect my honest impressions. My only previous liveaboard experience was to the Galapagos on a trip that cost me approximately $3500 per person for the week with a significant special discount. This liveaboard trip cost approximately one third that amount. I knew to expect less upscale accommodations and was not disappointed that the room was more basic. I gave the cabin and boat comfort three stars as compared to a more expensive and upscale choice, but I was not at all unhappy with either. The bunk room I shared with a roommate had its own bathroom with shower and filled all needs. While the bed wasn't terribly comfortable I was knocked out from diving and slept soundly (as did my roommate even though, I am told, I do snore!). The food was very good, but again, I am rating compared to a more upscale choice that would include more options. The staff, crew and dive guides are beyond compare - all were excellent - friendly, professional, knowledgeable. The crew and guides cleaned all equipment and suits for divers after each dive and were always available to help in any way. The dive guides had excellent knowledge of dive sites, marine life and diving. The diving was very good. I was fortunate to see a couple of mantas, but the whale sharks are hiding from me! Beautiful hard and soft corals, rocks and caverns, lots of fish. The views from the boat are also stunning. I am a middle aged-senior citizen American woman who was travelling alone and was on this trip with a large dive group (about 20 divers) from China, most of whom were significantly younger than me. I do not speak Chinese and only a few of the other divers spoke English. For me this was a wonderful opportunity to meet new friends and share experiences from our different cultural backgrounds. I thoroughly enjoyed the other divers and feel that we really enjoyed each other. If a diver will be travelling alone consider your comfort level with being in a similar situation. Great value - wonderful trip! Thanks, Smile Dolphin!

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!
