The tropical climate certainly provides its distinctive scenery, and may be easily recognized. Climate of course also affects many things in human life, including in the way they catch fish and the models of boats and canoes that are made and used so that they can float on the water. In Aceh, north of Sumatra Island, which has a tropical climate, in addition to the large boats used to catch fish in the ocean, there are also medium-sized boats that are used to catch fish in the sea around the mainland, and there are canoes that are usually only used at sea near the beach or in lagoons and fishponds near the sea.
