The parade of decorated boats between Setúbal and Caldeira de Tróia is the rite of the Feast of Nossa Senhora do Rosário de Tróia.
After a mass in honor of the deceased seafarers, in the Church of S. Sebastião, the devotees cross the Sado, in decorated boats, to Tróia.
On the first night, there is a procession of candles along the beach.
In addition to the religious ceremonies, there is a place for socializing at night, with dances and festivals. On the second day of the festivities, still in Tróia, the Decked Boat Competition is held.
Date of realization: second half of August
