Trip of a lifetime!

Definitely the trip of a lifetime! Not only was the crew the best and extremely friendly we also made life long friends. The diving was one of a kind, couldn’t recommend more and hope to come back again!

Great Experience!

The combination of perfect dives, flexible crew and beautiful moorage was divine. It was an excellent trip and such good company. Eric was really helpful and relaxed about my nervousness after a long time out of the depths, and I learned so much.

Great relaxing trip

Good diving (not similan quality, but solidly good). We did 11 dives during the 4-night trip, including one night dive. All the staff were good and eager to help with anything you need. Food was great, with tons of vegetables, curries, fish, chicken, etc. Eggs, toast and pancakes for breakfast. There was ample time to relax, take out a kayak, swim, visit a tiny island beach, or just read/nap on the giant deck. Rooms had a giant, good-quality bed, air con, fan, and private shower/toilet. I just wish the rooms had more hooks/bars for drying clothes. Massages were always available and the women did a really good, thorough job of them. Various alcohol and sodas were available all day/evening (though you of course can’t drink before diving). Coffee was terrible instant stuff. Overall a lovely, relaxing trip with nice diving. Highly recommend.

Great trip, great crew, great experience!

the ability to dive, relax and also have a variety of other things to do (kayak, snorkel, an evening on an island) --- loved it all!

1) the pace --- "dive and chill" is a perfect combination for people who like to dive but are not married to it; 2) the crew: the divemasters (Erik & Joe) were terrific --- really helpful and friendly; and what a pleasure to be able to be on a trip with the boat's owner Neil: an absolute gentleman who has more experiences than you can count but humbly doesn't bring them up unless you engage him in the discussion; 3) the diving: the boat has great gear, and there was a really nice variety of sites selected for our dives.

Amazing experience in beautiful location!

We had an incredible trip! It was beautiful and excellent diving. I was impressed with the rental dive gear, and our divemaster Erik was fantastic! The only disappointing part was that the AC didn't work (for any of the rooms) so it was very hot and hard to sleep. We heard they were planning to replace the ACs the next week, so hopefully it's better for future passengers. The rest of the boat and its amenities were top notch. We would absolutely book again and overall really loved our experience.

Amazing and Relaxing

It was just my fiance and myself as guests on the boat. Upon boarding the boat we were welcomed to a large common area with lots of room to relax in between and after diving and island/beach activities. The cabins were spacious with beds large enough to comfortably sleep two adults. The bathrooms were clean and the showers had plenty of cold and hot water. All the meals were prepared fresh and in abundance! There was so much food every meal, and all of it was delicious! Captain Addy was extremely familiar with the islands and was able to take us to many dive sites where we were the first divers there, allowing us to see undisturbed locations. Most days we would do two dives and relax the rest of the afternoon and evening. There was no "dive, dive, dive" mentality. Our dive master John was extremely knowledgeable of each dive site and even gave me tips to increase by bottom time considerably. The crew was very helpful in assisting us in and out of the water as well. The on-board massage found tension in me that I didn't even know I had! Our trips to some of the islands were incredible and had something for everyone. Between the beautiful scenery, delicious food, spacious accommodations, and highly-trained staff, I can honestly say this was the most incredible and relaxing liveaboard that we had been on.
