MV Oktavia

Thailand Liveaboards

MV Oktavia Similans Liveaboard

The MV Oktavia is a large and spacious Thailand liveaboard built in 2003 and then refurbished in 2007. At 29.5 metres in length and 6.5 metres in beam she carries up to a maximum of 20 guests although she actually has the capacity to carry a lot more. This means that there is a lot of free space for guests to relax in between dives.

With both 4 day/4 night and 5 day/5 night trips, she circles from Taplamu pier through the Similans and up to Richelieu Rock before returning to her starting point. 2 day/2 night and 3 day/2 night trips are also offered with speedboat transfers to/from the liveaboard allowing those with a limited amount of time to also enjoy the wonderful dive sites of the Similans Islands.

**Please note that this liveaboard is not currently in operation**
