Canoa de 3 paus, Montaria or Casquinho are names for the most common canoe used by river people in the Amazon region. It is built from three planks ( “3 paus” ) – one for the bottom of the hull, and two for the sides, each one at each side nailed to the bottom – of Itaúba or Sucupira tree and built with ease with simple tools, as a saw and hammer. Used with oars for family transportation and fishing. The lengths is on average 3 or 4 meters, however, may be larger. Sometimes they have covers for rain protection. It is used for native fishermen to work around their villages and transport their families.
