Boat Lagoon was the first marina built in Phuket. It is the center of a substantial real estate development, and the lagoon is ringed with hotels, restaurants, a hardstand area, shops and houses. The long dredged channel from Phang Nga Bay into the marina is a major problem since even shallow-draft boats have to wait for high tide to enter or leave. This lighthouse is not useful for navigation but the marina office is in its base.
