The Bacharel, together with other Europeans as Francisco Chaves, who also lived in Cananéia,
facilitated the approximation of Martim Alfonso and his crew to the Indians and the obtainment
of information about the area. The calm and protecting waters of the Lagamar were quite
favorable for the attraction of embarkations and the preparation of expeditions heading for
the interior of the country, moving up the Ribeira de Iguape river in search for the gold.
In the first decade of the 17th century, Cananéia presented a reasonable agricultural and
fishing production, serving as a food provider for the Portuguese troops who fought against
the Spanish at Rio Prata. There were lots of sugar cane and manioc mills distributed all
over the place, many products entered and left Cananéia and the maritime transport
increased significantly.
Several shipyards were constructed in Cananéia, the first ones at that time in Brazil, where
carpinters coming from
Rio de Janeiro
produced vessels which were famous for their excellent qualtity . In 1782, there were
16 shipyards in Cananéia having produced more than 200 vessels.
As fishing was not any longer sufficient to guarantee the subsistence of the population,
whale hunting was increasing substantially. At the Bom Abrigo island, there was a
factory installed where products from the whale processing could be purchased.
Those activities were very important for the local economy because the oil which was
obtained from the blubber and other parts of certain species of whales could be
widely used such as lubricant, candle and detergent or even
as combustion for the illumination of houses and streets.
