The moliceiro is Aveiro's icon: a slender, shallow-draught boat with a swan-neck prow, built to harvest moliço — the lagoon seaweed once used as fertiliser — and painted, by long tradition, with bright panels that run from saints and folk scenes to jokes broad enough to make a sailor blush.
Today the boats carry visitors instead of seaweed: 45-minute circuits leave continually from the Canal Central, gliding under the bridges, past the art nouveau façades, the old salt warehouses and the fish quarter. Tickets cost roughly €10–15 and operators line the central quay — no booking needed outside August weekends.
It is unashamedly touristy and entirely worth it: the city was built to be seen from the water, and the prow paintings alone justify the fare.

History & context
Moliceiros harvested lagoon seaweed for fertiliser into the mid-20th century, when chemical fertilisers ended the trade; the painted-panel tradition — devotional on one prow, satirical on the other — survived the conversion to tourism intact.
