Venezia - Vaporetti

Il vaporetto è un'imbarcazione tipicamente usata a Venezia come mezzo di trasporto pubblico, infatti, data la particolare conformazione della città, sono utilizzati i canali navigabili in mancanza di strade.

A vaporetto is a waterbus in Venice, Italy. There are 19 scheduled lines that serve locales within Venice, and travel between Venice and nearby islands, e.g., Murano, Burano, and Lido.

The name, vaporetto, could be translated as little steamer, and refers to similarly purposed ships in the past that were run by steam. The natives call the vaporetto batèlo or vaporino. The waterbus line is operated by Azienda del Consorzio Trasporti Veneziano (Actv), the Venetian public transport system. The vaporetto is necessary in Venice as deep canals prohibit building underground railways, and there is no space for overground trains, leaving the canals as the only viable rapid transport system. Most vaporetti have disabled people access.
