Beautiful diving

The guys on the boat were so friendly and helpful. There was always lots of food (even though I don't eat fish or rice, and the food was spicy most of the time). The rooms were comfortable and had more space than I've experienced before. Unfortunately, the compressor was broken so Nitrox wasn't provided as was listed on the website. Also, there was a leak in the water tanks somewhere so the boat had to do a detour to get water from an island (water was turned off overnight on the boat), and so the dive plan had to be altered. The ladder on one of the tenders broke one day during our diving. Also, a fan near the dining area exploded one day. I think the boat needs some down time for maintenance! Visibility wasn't great a lot of the time, but the corals were amazing and we saw so many species of fish and large schools of fish in many areas where we dove.
