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.

Great trip!

This trip was the “dive and chill” trip, which is a nice mix of diving and going to beaches. I did feel a bit shorted on the dives since we only did 6, but it was the rainy season so that happens. The crew was very kind and I had a great time! John (dive instructor) was awesome! Would definitely recommend!

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.

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.

The most relaxing and adventurous dive trip we’ve had.

Diving the Phi Phi islands was the highlight of the trip, but the crew is what made it so memorable. We even had a wonderful night ashore hiking to watch the sunset over Koh Phi Phi Don and then watched a beachside fire dancing show that was incredible.

The view from the cabin was amazing, the diving was great, and the daily massage were the perfect ending to the day.

Perfect and honest!

I can list all of the happy things that I encountered on this trip, from the diving, to the massages, sunrise, sunset, food, and so on... but the main highlight for me was just being able to have space to be away from the stress of every-day life. On the Merdeka3 I was able to relax and have my own rhythm. I did not feel pressured into an agenda, and everything happened very spontaneously and happily. There were 7 passengers on the boat which also meant there was plenty of living space - the diving instructors could give enough attention to each diver, and it was possible to get frequent massages. Our diving instructors Erik and John were extremely qualified, very friendly and attentive, and really pulled it all together - they are passionate about the work they do, and it shows; they went above and beyond for us. The AC was worthless, though sleeping with the cabin open also worked perfectly fine - the breeze was enough! I do know that the owners are currently installing new AC however, so..that problem should be solved in the future. Thank You for the best trip!!!

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.

A bit disapointing

Transfer to the boat, the sunsets, diving.

Recommended for
Very happy to get a ride from the airport to the boat with Neal. The boat is in need of some Tender Love and Care. And some of it is easy to do like changing the curtains which are torn now and changing the cusions on the sundeck which are falling apart. The aircon in the rooms are still not working but in earlier reviews it said they would be changed. The massage therapist did not speak any english which makes it difficult to tell her where your body ackes, I asked her for a massage BOW BOW (soft soft) but it was still pretty brutal, one massage was enough for me but when I booked I though to get a massage every day. The food was a lott but not always tasty. So overall I was disapointed on my Merdeka 3 trip

Went beyond my expectations

The name has it all, dive n chill. It was the perfect balance of diving, relaxation and exploration. The captain and whole crew were so friendly, they went beyond in ensuring my comfort and the food that was cooked up was so good!! Traditional Thai food and a splash of western (think chicken nuggets and fluffy pancakes) Highly recommend.

Great overall liveabord, space for improvement

The sites are great, with lots of dive diversity including cave dives, drift dives, pinacles, and a wreck dive. The diving team, including instructors and dive hands do everything for you to make the most out of the sites. Highlights were leopard sharks, porcelain crabs, turtles, glass shrimps amongst the diversity of fish: plenty of Moorish idols, clown fish and pelagics. There were mainly soft corals with lots of beautiful anemones, and some beautiful fans and brain corals. Engines running h24 and motor fumes coming down to the lower deck cabins. Maybe solar panels coupled with a battery park would allow powering off the motors at night?
