The 25m MV Explorer is a great option to explore the underwater beauty of the Similan Islands, Thailand. Dive with manta rays at Koh Bon, whale sharks at Richelieu Rock, and beautiful reefs at the Surin Islands. Walk on pristine beaches and trek into the jungle as the M/V Explorer takes you on 3-day and 5-day trips to the Similan Islands of the Andaman Sea. The experienced dive guides are more than happy to take requests to find special critters such as seahorses, pipefish, and nudibranchs.

Topside, the MV Explorer dive liveaboard has 8 cabins catering to 16 guests. There are 6 ensuite cabins on the lower deck: 2 are double cabins, and 4 can be configured as double or twins, depending on guest requirements. There are 2 double cabins on the middle deck. All cabins aboard the Explorer are air-conditioned, have sea view windows, and feature personal reading lights, 220v plug sockets, and ample storage space. Hungry divers will be taken care of as freshly prepared food is served throughout the day, meals vary between local Thai cuisine and international dishes, and vegetarians can be catered to on request. For relaxation, guests can choose the lounge & dining or the sun deck, which is also a great place to take in the stunning views and keep an eye out for playful dolphins.

The M/V Explorer is a great way to explore the Similan Islands and up to the Surin Islands and Richelieu Rock. Book online today to reserve your space.

Nice trip, beautiful dives and great value for money!
We look back on 11 wonderful days on the Seadragon Explorer, with her friendly crew and delicious food! It is not the most luxurious boat but the price is accordingly, but everything you need is there, the air conditioning worked fine and the shower was warm. The diving was generally very nice and the choice of where to dive was looked at daily. Can confidently recommend this trip :)

It's beautiful and memorable, and I look forward to seeing you next time
Everyone in the dive shop has a very good attitude, because of some special reasons and wrote an email with Stephen for more than a month, he is still very patient, thank you to every staff member of Sea Dragon~ In view of the few Chinese reviews in the past reviews, I will share a little bit with the wild buddy of Chinese who is hesitant in the follow-up. The boat is mainly in English, DM and other buddy mainly communicate in English, please determine your English level before choosing a liveaboard, otherwise there may be a relatively large communication barrier. The DMs are very enthusiastic and very technical, PPANG took a lot of beautiful photos for me, and every time they would happily ask me how I was doing and how I was sleeping. Love her so much!! pang，love u！ The other two young lady DM, Enia and Jess are also super cute, Jess is really beautiful, Maruci although he rarely communicates, but it can be seen that he is very responsible, and every night he shares communication techniques with his group members. The four members of the DM group are all amazing! We also saw sharks many times. The ship is new, and the room looks small, but it's actually enough to fit even a 28-inch box. The food eaten is mainly European and American food and Thai food, Thai food is very, very delicious! The young lady who works in the kitchen is very nice, she will secretly feed me every time I get on the boat, and the room will be tidied up between dives, and she will also help fold clothes. The other buddy on the boat are also very good, although everyone speaks different languages and comes from different countries, but every night there will be technology sharing, photo sharing, small talk, the atmosphere is very good, and on the day it ended, everyone was still hugging in the dive shop, pang also sent me to the car, pang love u again!! thx all the sea dragon DM and team！！

Can’t expect more from this trip
Special thanks to John, the boat supervisor and my dive guide of the first 5 day trip. His thorough intro to the boat, crew members, safety measures and the trip made it easy for me to get along with trip quickly. He also coached me with my diving skills. Not mention that he brought us to the leopard shark, guitar shark, mating cuttlefish, etc. Get ready early, think more underwater and move slowly on the boat - the three things in my mind throughout the trip~ Highlight of the trip: PI Yaa and PI Wee’s amazing cook! I could feel my wetsuit getting tighter and tighter 😂 PI Oi, PI Yaa, PI Wee, Khao, Bat, Nat, John, Tracy, Jong, Pang, Karlos and Sea Dragon Dive Centre - THANK YOU ALL!

Red Sea Dragon and The Explorer were awesome ♥️
Loved this trip from the moment we met everyone at the dive centre to getting onboard, everyone was so friendly and felt like one big family. Food was really good. So many meals ! Great having free soft drinks and plenty of water available. The guides were really good and made the briefings fun aswell as informative. The deck crew were really helpful and one big team. One downside, the beds were so hard. We do have a firm bed but they were really firm. Consideration might be given to a few bed toppers (chargeable if required) to hire.

Narrow cabin, otherwise top: crew, dive sites, intensity – it was a lot of fun.
Cramped cabin and sleep on the mattress on the floor. Otherwise, everything was excellent. Friendly, courteous crew, experienced guides, versatile dive sites and dives. Surin and Similan, Tachai and Richelieu Rock. Shore excursions in beautiful, remote places. We had 3 days and 5 days, with a stopover in port, diving every day. Many days with 4 dives. Thank you very much, it was fun.

Real night dives, not just sitting under the boat. And versatile dives at a wide variety of dive sites. Diving operation, well organized, very helpful, very friendly crew, not only in diving operations. Great food, varied and different at every meal (2 x a day + breakfast), tasty, always to full..

Great dive guides, amazing chef, and nice dive sites
The experience with the explorer was great. The dive guides ( Champ and Ori) were one of the best if not the best dive guides I have ever met. There care for the coral was impressive, as well as there knowledge about the animals ( after each dive we sat together and went over the animals we saw). Ori also acted quickly if there were problems on the boat or within a dive group. Overall, a 9/10 would do this trip again (5 days + 3 days), two different trips back to back.

Fabulous Trip - Fun & Safe Adventure
I actually like scuba diving. I do not necessarily love it. I was able to choose which dives I went on and stay on the boat and read when I didn't want to go on a dive. The locations we went to were gorgeous. The guides were knowledgable, fun and caring. The food was great! I shared a cabin with my friend and I enjoyed the luxury of just having the two of us in a room. The rooms are quite small so make sure to pack minimally. The dive shop will lock up your extra gear safely for you while you are away. I would do this trip again in a heart beat.

Amazing diving vacation with a great team!
We booked a 6 days / 5 nights trip from Surin island to Similan Islands. We had 18 dives in a beautiful and preserved submarine environment. We had the chance to stop by a wonderful beach and a gipsy community. On board, the team was amazing, the diving instructors and the boat crew were professional, competent and funny. The thaï food was delicious and the boat was comfortable.
