Canoa de Pranchão is recognized as the first model of boat traditionally developed in the region of the estuary of Lagoa dos Patos. These canoes were very common from the 19th century to the beginning of the 20th century, but little by little they were replaced by other models of boats. As a Cultural heritage two canoes (seen here in photos) of Canoa de Pranchão were recovered, all owned by the local Nautical Museu in the Rio Grande do Sul.
The hull was built with 48 to 50 Cedro 1.5 to 2.0 inches planks, shaped by small hand axes and fixed symmetrically to each other with nails and pegs on just three master ribs. The boards were cut out and set like a jigsaw, to ensure the sealing between the various parts that formed the canoe.
The Canoa de Pranchão were used for fishing in the region and had cargo capacity between one and seven tons, powered by rowing oars or sailing under three sails: main, mizzen and jib, all dyed with the purple dye extracted from the bark of the Capororoca (Myrsine), a small tree typical of the estuary region.
