The trabucco is an imposing structure made of structural wood, consisting of a platform extending over the sea anchored to the rocks with large Aleppo pine trunks, from which two or more long arms, called antennae, extend a few meters above the water, supporting a huge fine-meshed net called a trabocchetto. The different coastal morphology of Abruzzo and Gargano has led to the presence of two types of trabucco. The Gargano type features a platform anchored to a rock spur and extended longitudinally along the coastline, from which the antennae branch out. The Abruzzese type, technically called a bilancia, is typical of shallower coasts and has a platform positioned transversely to the coast, connected by a wooden footbridge. The bilance generally have only one winch, often electrically operated, and a smaller net compared to that of the Gargano trabucchi. Another difference concerns the length and number of antennae, which are longer on the Gargano than in Abruzzo and Molise. In Termoli, the bilance have a maximum of two antennae, whereas on the Gargano and in the northern Bari area—in Barletta, Trani, and Molfetta—there are always two or more antennae.
