This is a typical liveaboard dive boat on which a group of scuba divers lives for several days while diving at various sites. We've heard that each customer makes two to four dives per day, including some night dives. They all hope to see the Manta Rays and Whale Sharks which migrate through the Similans, as well as many types of reef fish, colorful corals, sharks and other inhabitants and visitors. The clear water and abundance of corals and animals make this one of the world's top diving destinations. We could only guess why this boat had a tent on top.
