I went solo on the New Years cruise doing the Central Maldives itinerary (anti-clockwise direction from Male). This was the first Maldives liveaboard I have done so not much to compare against but it seems clear that the Yin and Yang are amongst the very best if not the best boats operating out of Male. I had a Dolphin suite on the main deck and requested the one that was not furthest forward to not be next to the anchor pocket. The room was excellent in size and cleanliness (room serviced 2 or 3 times a day). The boat is run very well by Thomas and then the diving aspect by "V". Both of them were very professional and excellent in answering any questions or issued that arose. The rest of the crew are also excellent and it really is a 5 star operation. The food is very good too although I wouldn't go quite as far as to say it is better than food at the resort islands. Great bar and barman on the main deck aft and altogether a very nice atmosphere on board all week with a good mixture of customers from around the world (no nationality too dominant).
