This form of transportation is not unusual if you live in Venice, Italy. A vaporetto is a boat that is like a bus except it stops at a pier to pick up passengers. Vaporetti (plural of vaporetto) carry more people than traghetti or gondolas.
In 2004, a ride cost five euros. Each vaporetto has its own route and stays only on that route. Each vaporetto has two workers: one driver and one person who lets the passengers on and off. The person who lets passengers on and off is also responsible for tying up the boat each time it reaches the pier.
