Wow, we rate this to be one our top 5 experiences in life, it was beautiful, challenging, & relaxing.

Morning sunrise, and evening sunsets were breathtaking. Food was authentic and delicious. Crew was AWESOME, we learned so much and everyone went above and beyond to ensure every need was met. We stayed in the master cabin, definitely worth you extra money. You on the top living deck, with your own bathroom and shower; we enjoyed having the privacy.

Amazing Whale Shark sighting!

I snorkeled while my husband and daughter dove. The guides not only looked after the divers but me as well. My husband got his Advanced deep water certificate and Vanessa took time to make sure he understood everything above and below water. The other guests were so much fun to meet from places like Switzerland, England, the US & Australia. They all raved about the dives at Richelieu Rock. “Soooo many fish!!” they said. But my best snorkel came at the end. Victor, my guide, and I were snorkeling one end of the Koh Bon while the divers were at the other end. There were so many fish. Then he spotted a green turtle just gliding along in and out of the darker water,so peaceful. Suddenly he grabbed my arm. I thought sure there was a big problem. I looked where he pointed and out of the darkness, gliding 8-10m below us was a WHALE SHARK!!!! Unbelievable if you have never seen one! So peaceful, beautiful and huge. Apparently, they are rarely seen there. We were so blessed!!! Before we could even get in the boat, Victor was shouting to the crew the Thai word for Whale Shark. He was so excited. We were the talk of the boat for the rest of the trip. Many thanks to this wonderful crew for the highlight of our 10 days in Thailand!!

Good first liveaboard

This was my first live aboard, so I didn’t quite know what to expect. 4 dives a day was a bit much, but the dive spots were nice, especially the dives in Richelieu Rock were amazing, and makes it worth doing a longer cruise. The crew and guides were very helpful, and made effort to accommodate different needs and levels of diving. The cabins were quite basic, but adequate compared to the price.

Three of the best days in my life

As an rather unexperienced diver it felt really awesome how the diveguide were adjusting to your level, and it wasn’t like we were missing out on anything, we still got to see manta, a LOT of different kinds of morays and fish and slugs and all you could ever dream of. My logbook didn’t have room for all the awesome creatures we identified together. Next time I will definately go for the full five days.

Good food and big schools of fishes

Koh bon, koh tachai, Richelieu rock are so nice. Many big schools of fishes make it memorable. Briefing is effective with introduction of sites and marine lives. Food is really good. Thai crew are nice. Better to have good buoyancy control because some sites have rocks and narrow passages.

Very nice trip

The crew was super nice and friendly. It.was m'y first liveaboard cruise so I don't have other expériences to compare. But the ship was nice. The chosen sites were good and we saw some very interresing sea life ( 3 Big manta rays) The captain was very proficient and pickups were always easy The guides knew the diving sites and were efficient. Équipement was good

Not worth the money

This liveaboard is a very disappointing experience. The crew doesn't spend much time with the guests on the boat, instead spending time with each other. The quality of the dives is very poor, with the guides appearing uninterested. The dive guides rarely point out anything during the dives, and they don't try to make the dives entertaining. Multiple times my tank wasn't filled prior to my dives, and on 3 occasions my wetsuit went missing, and when I brought it up to the trip leader, he shrugged his shoulders and proceeded with what he was doing. Really disappointed by the experience on this boat.

A great voyage with one reservation

Manta rays and whale sharks on 3 consecutive dives in Feb! However ... I was appalled that several divers behaved in a shameful way when we were blessed to see a magnificent whale shark. Several divers ran at the creature - two of them grabbed it!!! Only the Thai dive instructor on board tried to stop them. It was upsetting to see such behaviour. Divers MUST be warned and briefed to stay still and just witness the beauty... the creature will stay longer... and I won’t feel I’m taking part in destructive diving. Sorry to rant... but it was a magical moment spoilt by poor order and briefing. Thanks

Great diving with great dive operator

Dom take care of us so much before and after the trip. Before the trip, we have many questions, he replied very quickly trying to solve all our problem. Dive guides so friendly. Trying their best to show us what we want to see. When we want to see big creature, they gave us oceanic manta; when we want something bigger, they show me whale shark(s). Great job and professional. Cabin is comfortable and big. Plenty of space for us to settle our big luaggages and camera gears. Highly recommend

Amazing experience over 5 days of diving with a very friendly crew. (WHALE SHARKS AND MANTA RAYS)

I was lucky enough to get a room to myself which really meant that I slept well and was ready to dive come the morning time, which is important when you're doing 4 dives a day. I went in February 2020 and the conditions were very calm, with water between 25-28°C all the time. Visibility wasn't as good as it normally is (according to those who had dived there before) but it was still about 20m which is pretty good. The food was plentiful, although sometimes a certain dish would run out quickly if you weren't in fast. There was always fruit to snack on or toast, coffee, tea etc and it was never long in between meals. Victor, Vanessa, Hiep and Marja all were very friendly guides who answered all questions as they were asked and made life easy organising dive gear or fixing issues. I think there are cheaper options out there for those who want to save money, without sacrificing too much quality. I think this boat was marginally more expensive and on the last day with park fees, tips and gear rental you'll need to remember how much you are really paying for the trip. On our last day of diving we saw Whale sharks on all 3 dives and on the last dive it literally hung around for 40 minutes. It was the most amazing thing to witness and I couldn't, still can't believe my luck!!! On top of that we had Manta rays, morays, cuttlefish, octopus and giant schools of travelly and emporer fish. But the whale shark swimming around us feeding for 40 minutes will live with me forever.

(1) The relaxed vibe of the boat was exactly what I wanted, rather then be forced to do all these activities, everyone was welcome to spend their free time as they pleased. (2) The dive sites themselves were fantastic for the most part, there was more often than not something interesting to see or a "first time" viewing of something. (3) The boat was spacious and there was room for everyone to lie down if need be, it was very comfortable and the crew were always helpful
