A "moliceiro" is a traditional boat found in the Ria de Aveiro, a lagoon in Portugal. These colorful, flat-bottomed vessels were originally used for harvesting moliço, a type of seaweed, which was important for agriculture. Today, they are often used for tourism, offering scenic rides through the picturesque waterways. Moliceiros are characterized by their vibrant decorations and unique shapes, making them a symbol of the region's cultural heritage. The boats are typically made of wood and can accommodate several passengers, providing a charming way to explore the natural beauty of the Aveiro area.
