The vital craft of boat-building, fundamental to the existence of all river peoples, is the work of a group of specially skilled Bozo men. The hard timber, brought from the coastal rain forests many miles away, is skillfully converted into the long, narrow boards in which the Bozos fish, trade, and even move their families, as the seasons change. Careful camera work details how glue, nails, strips of cloth and even mud are used to make the boat watertight.(1984 IFF catalog)
