Our family owned Similan Islands liveaboard vessel MV Oktavia is 30 metres long and 6.5 meters wide, which makes her one of the largest Khao Lak Diving vessels operating in the area.  This also makes her a very stable platform as we cruise through the Similan and Surin National Marine Parks.  Her size naturally allows plenty of room for all our guests to relax and enjoy the scenery between dives.  With our spacious cabins and plenty of delicious freshly prepared food you can be sure to be well catered for.  All great reasons to join us as we discover why Similan Islands Scuba Diving is widely considered to be the best and most exclusive diving in Thailand!
