Diving on the Oktavia liveaboard in Thailand

The MV Oktavia guarantees adventure cruising with a complete experience with diving, snorkeling, excursions on the islands, treasure hunts, jungle walks, beach football, and marine life presentations. The boat is a perfect fit for anyone interested in experiencing an amazing liveaboard trip.

Boat features

The upper deck of this unique liveaboard which is commonly referred to as the “party deck” is equipped with an Audio-Video entertainment system, library, a bar, and board games. The party deck also serves as a dining room during meals. The boat also has a large sundeck which offers plenty of space for guests in between dives. With part of the sundeck shaded, guests with sensitive skin can enjoy the fresh air while taking in the sea’s view.

The MV Oktavia has 13 standard cabins located on the lower deck and two master cabins on the upper deck. The cabins on the lower deck share four bathrooms. The standard cabins have central AC, a fan, either a double or 2 single bunk-beds plus cupboards for storage. Master cabins have a TV & entertainment system, seating area, writing desk, storage, and double beds.

The best Similan diving liveaboard trips can be difficult to choose due to trip lengths and schedules. However, MV Oktavia has a novel solution. Most of the cruises are five days and five nights in length, but there is an option to only go out for two or three days. This is done merely by speedboat transfer to or from the ship which stays out at sea for the full five. One option is to sail out on MV Oktavia at the beginning of the dive cruise and return on a speedboat after two days and nights at the Similan Islands. The alternative is to take the speedboat out for the second half of the cruise, which visits Koh Bon, Koh Tachai, Richelieu Rock and Boonsung Wreck on a 3D/2N 10-dives itinerary. Those who are lucky enough to enjoy the complete 5D/5N cruise visit all the locations and get to dive 19 times. At the beginning and end of the season, Oktavia offers 4D/4N 15 dives trips, which are comparable to most other liveaboard trips offered on our other boats.

With 14 crew members to attend the needs of guests, this liveaboard is a diver’s dream. The meals in the boat are served buffet style and are a mix of international and local cuisine. Snacks are available all day with hot beverages also provided.

With guest’s safety a priority, the Oktavia liveaboard carries safety equipment for safe passage. The safety equipment includes oxygen, a DAN tank, first aid kits, SOLAS life jackets, and two SOLAS life rafts. The boat has communication that includes CB radios, VHF radios, a GPS radar, echo sounder, and mobile telephones. The boat also offers Nitrox and has both indoor and outdoor comfortable saloon common areas.

The boat offers 2D2N, 4D4N & 5D5N trips. The destinations for 3D2N trips have no beaches open to the public. The 5-days 5-nights cruise to the Similan Islands, Koh Bon, Koh Tachai, Richelieu Rock, Boonsung Wreck includes 19 dives. The 4-days 4-nights to the Similan Islands, Koh Bon, Koh Tachai, Richelieu Rock, Boonsung Wreck includes 15 dives.
