Diving is unlike anywhere in the world. Boat is old and the trip is expensive for what you get compared to other liveaboards elsewhere in the world. Crew was not on top of their game. Very nice people but service was not commensurate with the cost.
The dives require experience with cold water and currents and I would not suggest this for a diver without specific experience in similar conditions. The guides will not give much individual attention and with so, dives uncomfortable situations can occur when divers have different experience levels and air consumption.
