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

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

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.

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

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.

Tutto ottimo! Forse un po' meno di spigoli vivi sulla barca, però sono dettagli.

Tutti. Peccato solo non aver visto nessun pelagico, però per fortuna il mare non è uno zoo. Le immersioni sempre con poche altre barche intorno o anche nessuna.
