Here is some feedback from two guests on Oktavia in late April. It's pretty typical of what people think of Oktavia.
Hi Paul
We had a great trip on the Oktavia. The crew was very friendly and so was the owner who was also on the trip.
The boat was the best liveaboard I have been on in Thailand and the food was great.
The diving was exceptional with 15 dives 4 of them on Richelieu Rock which is one of the best dive sites in the world.
Thanks again for all your help,we had a fantastic time.
Thanks
Cliff and Anna
