The word catamaran is original coming from the Tamil word katamaram meaning maram=tree kata=bound together. Five or seven trees are bound together with coconut-rope and the bow is seperatly fixed slightly cut to a point and put upwards. Those boots are rather heavy and it takes 4 man to carry them to see. The plastic blue sail is nowadays replaced by an outboard motor, less pittoresk to see them at see.
Here you see no sail or motor as the small katamarams are used to catch prawns. Lately it became less rewarding as many prawn-farms are started up and the seawater became more poluted by the big hotels draining their dirty water into the sea chasing the prawns away.
