The gondola is a traditional, flat-bottomed Venetian rowing boat, well suited to the conditions of the Venetian lagoon. It is similar to a canoe except it is narrower. The rowing oar, which is not fastened to the hull, is used in a sculling manner, also acting as the rudder. For centuries the gondola was the chief means of transportation and most common watercraft within Venice. It is propelled by a gondolier. In modern times the iconic boats still have a role in public transport in the city, serving as traghetti (ferries) over the Grand Canal. They are also used in special regattas (rowing races) held amongst gondoliers.
