what is now the downtown area of the city. Land reclamation and conversion to other uses means that downtown area no longer handles commercial traffic, although the US Coast Guard maintains a major base there, and there is still considerable ferry and leisure usage. Today the principal cargo handling facilities are located in the Boston neighborhoods of Charlestown, East Boston, and South Boston, and in the neighbouring city of Everett. In 2011, the port handled over 11.5 million metric tons of cargo, including 192,000 container TEUs. Other major forms of cargo processed at the port include petroleum, liquefied natural gas (LNG), automobiles, cement, gypsum, and salt. The Black Falcon Cruise Terminal situated in South Boston, was renovated and expanded in 2010. During 2012, it served 117 ships and more than 380,000 passengers. Passenger boat services The MBTA Boat system comprises several ferry routes on Boston Harbor. One of these is an inner harbor service, linking the downtown waterfront with Boston Navy Yard in Charlestown. The other routes are commuter routes, linking downtown to Hingham, Hull and Quincy. Some commuter services connect via Logan International Airport. All services are operated by private sector companies under contract to the MBTA. Outside the MBTA system, seasonal passenger ferry services operate to the Boston Harbor Islands, to the city of Salem north of Boston, and to the town of Provincetown on Cape Cod. Water taxis provide on-demand service from various points on the downtown waterfront and from Logan Airport, and in particular between the airport and downtown. Several companies operate tourist oriented cruise boats on the harbor and on the Charles River. Other companies operate duck tours that use amphibious vehicles (mostly derived from World War II era DUKWs), and encompass both the city's streets and its waterways. On a much smaller scale, but perhaps more iconic of Boston, are the human-powered Swan Boats on the lake of the city's Public Garden.
