first official pilot in Rio Grande do Sul
was Gaspar Santos, sent by the Brigadier Silva
Paes to discover sand banks and channels in
the bar of Rio Grande, where he, later on,
remained serving as a pilot.
pilotage navigation on Laguna dos Patos
starts to be mentioned from 1750 on, when
General Gomes Freire de Andrada became responsible
for taking the troops and preparing the
land for the arrival of the Azorean immigrants.
Gomes Freire believed that the most logical
waterway for the distant Missions would
be to break through Rio Grande bar, go up
Laguna dos Patos and from there to move
towards the west on Jacuí river.
However, from the beginning, he has been
informed about the difficult conditions
for the pilotage on the lagoon, because
there was not a navigation channel among
the treacherous sand banks. In 1795, the
pilots of the bar already had a small scull
that went and came through the bar, signalizing
the level of the sand banks to the vessels
that went to the port of Rio Grande.
On the 15th
of November of 1802 the positions of head
pilot for the ports of Pará, Bahia
and Rio de Janeiro were created, and the
preference fell upon the Portuguese who
have already carried out the job in Lisbon.
In Rio Grande do Sul, this function belonged
José Francisco Rosa, at the expenses
of the Governor of the Capitania. In 1803
the position passed to Francisco Marques
Lisboa, father of Joaquin Marques Lisboa
(Fleet Admiral Tamandaré, protector
of the Navy). In January 1808, the regal
letter of Dom João VI, which opened
the Brazilian ports to friend nations, created,
the position of pilot with a Decree, signed
in June of the same year.
