In São Vicente, located on the coast of São Paulo, both a boat and a ferry sank at the Ponte dos Barreiros on October 10 as a result of a phenomenon known as 'maré enquartada' or dead tide, characterized by minor differences between high and low tides. According to the local government, this situation caught the crew by surprise but fortunately, no individuals sustained any injuries during the incidents.

An eyewitness recounted that the boat was docked when the sinking began, prompting the boatman to leap safely onto the pier. At the same time, there was a team aboard the ferry who were also able to jump onto another ferry before their vessel went under. This quick action ensured that everyone remained unscathed, illustrating the importance of preparedness in maritime situations.

Following the incidents, the Municipality of São Vicente announced that the submerged vessels were retrieved by the consortium managing the restoration of the railway section near the Ponte dos Barreiros. Furthermore, city officials confirmed that ferry operations have since returned to normal, providing a sense of reassurance to the local community affected by the unusual weather conditions that led to the sinking.
