Arenui is a new but a very well set up & run diving operation. Gerry, gives very informative and entertaining dive briefings with lots of details and clear diagrams. The boat is well set up for diving & very comfortable for relaxing between dives. Up to 4 dives per day are offered (including night dives) which sometimes are better than diving during the day. Overall a highly professional Liveaboard that I would recommend very highly.
