Great fun! I was on the boat in spring 2013. The room were very comfortable, a little small with bunk style but plenty for me(single traveler that trip). Plenty of warm water. The crew was great and made sure we were safe but not overbearing.
After the night dives they poured warm water over your neck which felt awesome since after 4-5 dives in a day I was getting a little cold. Plenty to eat, buffet style, good food. Snacks almost always available. The diving was fun, plenty of gray reef sharks who just want to hang with the divers. No one was bothered by them. Nice variety of small and large fish with healthy coral and invertebrates. Would definitely repeat this trip. i'll pack warmer clothes next time, long sleeve t-shirt or two, fleece.
