Amazing Dive Vacation

We were luck to have only 10 guests on board so all single travelers had their own cabin which is pure luxury on a Liveaboard Tour! The cabins are small but good enough for sleeping exhausted after a day of diving. The Housekeeping and food supply was awesome. Our cruise director Glenn did a great job in keeping us out of the crowds during our dives (esp. at Richelieu Rock!). Our Dive Guides were superb, I am not super experienced and felt very safe during all the dives, even with varying conditions. All in all: highly recommended!!!

Very well organised and high quality Liveaboard

The 4 dives in Richelieu Rock were impressive in the abundance and diversity of marine life, soft and hard corals. The food on board was much better than what i used to get in other liveaboards. Any type of cooked eggs for breakfast, Thai for lunch, 3 course meal for dinner, nice white wine, all drinks are complementary. The service was very attentive. All staff help out and are very smiley. Even the chefs help out take the divers gear out between meals. Jinni the stewardess looked after passengers like a mother, handing over towels, food and drinks. Clive the cruise director is a well of diving experience and maintains the cruise, diving and hospitality standards to a very high level. He is also relaxed and friendly. The dinghy drivers were highly skilled at dropping us off and picking us up even by night and very helpful. My only negative feedback is that the wifi should be upgraded to handle the data needs of passengers and staff as it didnt work very well even when mobile network was available from the shore.
