In free translation, my own faults, it says:
Ericeira was recognized as the fourth border of the country, following Lisbon, Porto and Setubal.
The trade boats of Ericeira, called "Rascas" were 20 meters long with 3 masts and 4 sails.
They went to Brasil, 4200 nautical miles away, and back frequently because there lived a fair number of people from here.
