The fishing fleet of Grado reached its peak at the end of ā800.
Boats with flat bottom like ābateleā, suited to sail the shallows of the lagoon, or like the āspiferiā which we can see in the picture: boats with rounded bottom, provided with a keel, also able to sail open sea. The āspiferiā with the advent of the engine, have superseded the ābragossiā, fishing boats which were common in the High Adriatic Sea.
