According to tradition, an image of the Virgin appeared in the port of San Vincente de la Barquera on an Easter Tuesday in a boat with no oars, crew members or rudder. To commemorate this fact, the inhabitants, in particular seafarers, take part in a peculiar procession in which they escort their Virgin, dressed in her blue robe, through the streets of the town and then place her in a boat. A large number of boats go with the Virgin, all of them decorated with flowers and flags.
