Great Experience on the Giamani
Very satisfied! Dive master did an excellent job. After 40 years of diving, still saw and experienced new marine life. The limited number of passengers made entry and exits for diving very easy.

First Liveaboard and definitely not the last
I was very cautious going on a liveboard with only 4 dives under my belt. As soon as I got there my ease was to put to rest. The dive instructors always have a great briefing per dive advised of the pros and cons and always ensure we never adventured out of it comfort zone.

A great liveaboard with personal service
The great thing about the Giamani is that because it is a relatively small boat you are guaranteed almost exclusively dives, with small groups. The quality of the dive leaders is good, and their knowledge of the dive sites is exceptional. Nothing is too much trouble for any member of the crew who are all there to give you a fantastic diving experience. The food is great quality and plentiful, catering for all tastes. Richelieu Rock is an amazing dive site - truly a world top ten and at last being properly protected by the Thai authorities.

Professional dive guide and kind boat crew.
It’s a very fruitful diving trip having being seeing many marine life. In the meantime, it’s also very educational. The dive guide gave thourough briefing before each dive, letting you know the geography of the dive site and sometimes with little history behind. Underwater, you know you are very safe. The dive guides are always watching your back, reminding your to check the air and the depth. Overall, I love Giamani.

It couldn't be better.
We had a great time on the boat. Since the ship has only few rooms, it immediately feels like a family trip. The tour leader Dima cares very intensively that everybody enjoys the trip. He is also a very passionate teacher and explains the lessons and the briefing very patient. The other divemasters on the boat, Alina & Francesco lead the divers in their group also very sensitive and show a lot of hidden animals. The crew is very helpful with the equipment and the entry/exit to the boat. We would book it again.

Great Service and feeling of private tour
The Richelieu Rock dive site was amazing. Small group people on the boat (max 10) and smaller groups when diving. Great service and judgement by crew (adjusting schedule to the weather conditions and considering different timing for dives on popular sites to avoid crowd) made the time on the boat fun and easy. Great personality of the dive instructors, who were well synch and approachable, always ready to explain and share tips and tricks with you.

Fewl like a King, dive like a Seal
Loved Dima, fhe whole crew, and the ship! The boat is more personal for divers, as it fits fewer divers than some of the bigger boats out there. As a result, you get a more personalized experience, better conversations, and an overall more "this is for me" experience. All ships go to the same dive sites, so the boat you go on makes a massive difference. Ive been on a few liveaboards, and Giamani is by far my favorite.

Great boat, great dive team, great crew, great diving, great food! What else could you want?
We saw at least 80% of all the fish in the dive books. There is also loads of macro life, various shrimps, crabs, nudibrachs and a wide variety of corals. Great under water topography makes for interesting underwater scenery. Above water the dive team were professional, knowledgable, safe and great company in the evenings too. The boat crew tended to our every need, they even hang up your wetsuits at the end of each dive. Chef was fantastic and cooked a huge variety of quality food.

Great trip that improved my diving skills!
I had the 5-day Similan, Koh Bon, Koh Tachai, and Richelieu Rock trip. What a trip! Ric helped me improve my diving skills throughout the trip as I got the AOW certification. Meals and snacks were delicious and it was great relaxing on the sundeck after every meal and dive. Unfortunately, Koh Tachai did not meet my expectation, but other dive sites - Koh Bon and Richelieu Rock offered amazing scenes. The crew members and Van the dive guide were all friendly, as well. I'd recommend Giamani.

An Exceptional Diving Experience
Had an absolutely wonderful liveaboard experience. The crew has been together for years and are a well-oiled machine and adept at handling any and all experiences. The boat was immaculately maintained, the private chef provided a plethora of culinary options, and the dive sites were fantastic. We dove a wide range of caves, caverns, ship wrecks, and multiple reefs and are leaving better divers and more in love with scuba diving than before. We could not have had a more positive experience and we will absolutely be back to dive again and extend our time on this boat and have already recommended this boat and experience to other divers.

Amazing Hospitality with A few Diving Issues
The wreck dive, the food, the scenery, the organization of the entire experience. However, I had some issues with the diving. I was doing the advanced certification, and while Ricardo is incredibly experienced and confident, I didn't feel he made sure I was comfortable at every step of the way. He made a lot of unilateral decisions and I didn't feel I had the opportunity to push back or ask questions so that I felt comfortable with each step. I did feel safe, however, as Ricardo is a dive master to the extreme. I just think he's so confident that sometimes he forgets how new it can be for us beginners.

Fantastic crew and diving
Dima and his boat crew were fantastic, they are friendly, happy people, passionate about diving and conservation of the natural beauty. We loved the fact the boat only accommodates limited numbers of divers; on our week-long trip we had 6 divers, all of whom were highly experienced. The crew have worked long term on the boat, with the captain very professional and engaged on Giamani since it was built. Dima had excellent underwater navigation and spotting skills, meaning we saw marine life normally difficult to spot. The boat cabins are a little tired, but we didn’t care as we spent so little time in them. Overall an excellent trip.
