Our lovely boat, MV Thai Sea

With its 5 meters wide and 20 meters long on 2 decks, the MV Thai Sea offers its happy guests a smooth and safe journey in the Surin and Similan National Marine Parks in Thailand as well as in the Mergui Archipelago in Burma or Myanmar.
This attractive boat in traditional wooden style welcomes 12 divers on board.
You will feel as if you have chartered the boat for yourself.
The boat has an open and comfortable lounge area where meals are served buffet style and we promise you will never go hungry on M/V Thai Sea.
Our sun deck area can be partially covered so you can choose between relaxing in the sun or go for the more chilled covered area for your leisure.
On the technical deck, the equipment platform offers an individual place for each diver with plenty of space for your scuba gear. We dive in individual groups so it is never crowded on the deck when we gear up.
Our photo area with a charging station and rinsing buckets for electronic equipment is conveniently placed right before the dive platform so you can grab you equipment on the way.
The large diving platform is also bordered by only one group at the time. M/V Thai Sea is 5m wide so we can comfortably all line up next to each other and still have plenty of space even in scuba gear.
The dive platform have 2 fresh water rinsing showers and quick rinse bucket for just out of the water and “other than electronics” to keep the electronics buckets salt free. 2 diver friendly ladders easy to climb in full scuba makes it the perfect dive platform. If you need a hand, there are always lots of them around when we are diving.

The cabins on MV Thai Sea

M/V Thai Sea offers one Master Cabin with double bed and scenic view both forward to the stearn and sideways to the port side.
5 bunk bed cabins spacious enough for the duration of your stay. In ONE bunk can be turned into a double bed. Please specify when you make reservations or inquiries.
All cabins are well ventilated and equipped with individual fans for each bed. In 4 of the bunk bed cabins the roof have a huge hatch you can keep open and the fresh sea air vil naturally ventilate your cabin. The last bunk bed cabin have two sided windows and so does the Master Cabin
All cabins come without air con.
Bring minimum of luggage. You do not need much on a boat in the tropics and leaving some luggage on land in Thailand keeps your luggage free of the sea air and leaves it fresh for your return. Leave it at your hotel or bring it to our office in Ranong, Thailand for safekeeping during your liveaboard cruise.
M/V Thai Sea have plenty of storage room if you chose to bring more luggage on the safari.
Toilets (3) and shower rooms (2) (and the 2 open air showers) are shared.
Come be our guest on M/V Thai Sea and enjoy a personalized service, just like at home. Always full service from our experienced and attentive team.
