Longtail Boats are one of the primary transportation methods around any water way within Thailand. Here on the island of Ko Pi Pi they are used to transport tourist out to various scuba locations and tours of the surrounding islands. In less tourist filled areas they are used for basic daily transport and fishing. The extended rudder which sticks out about 15 feet allow the longtail boat to skim easily through very shallow waters.
This photo was taken only about 18 months after the devastating Tsunami which wiped out much of the town on the island. As you can see it was back in action very quickly.
