A ferry (or ferryboat) is a boat or ship (a merchant vessel) used to carry (or ferry) primarily passengers, and sometimes vehicles and cargo as well, across a body of water. Most ferries operate on regular, frequent, return services. A passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water bus or water taxi.
Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. However, ship connections of much larger distances (such as over long distances in water bodies like the Mediterranean Sea) may also be called ferry services, especially if they carry vehicles.

Speculation that a pair of oxen propelled a ship having a water wheel can be found in 4th century Roman literature “Anonymus De Rebus Bellicis”. Though impractical, there is no reason why it could not work and such a ferry, modified by using horses, was used in Lake Champlain in 19th-century America. See “When Horses Walked on Water: Horse-Powered Ferries in Nineteenth-Century America" (Smithsonian Institution Press; Kevin Crisman, co-authored with Arthur Cohn, Executive Director of the Lake Champlain Maritime Museum). See Experiment (horse powered boat).
The busiest seaway in the world, the English Channel, connects Great Britain and mainland Europe, sailing mainly to French ports, such as Calais, Boulogne, Dunkirk, Dieppe, Cherbourg-Octeville, Caen, St Malo and Le Havre. Ferries from Great Britain also sail to Belgium, Denmark, the Netherlands, Norway, Spain and Ireland. Some ferries carry mainly tourist traffic, but most also carry freight, and some are exclusively for the use of freight lorries. In Britain, car-carrying ferries are sometimes referred to as RORO (roll-on, roll-off) for the ease by which vehicles can board and leave.
The busiest single ferry route (at least in terms of the number of departures) is across the northern part of Øresund, between Helsingborg, Scania, Sweden and Elsinore, Denmark. Before the Øresund bridge was opened in July 2000, car and "car & train" ferries departed up to seven times every hour. In 2013, this has been reduced, but a car ferry still departs from each harbor every 15 minutes during daytime. The route is around 2.2 nautical miles (4.1 km; 2.5 mi) and the crossing takes 22 minutes. Today, all ferries on this route are constructed so that they do not need to turn around in the harbors. This also means that the ferries lack natural stems and sterns, since the vessels sail in both directions (rather than "sail backwards"). Due to the same circumstances, starboard and port-side are "dynamic" and depending of in what direction the ferry sails. Despite the short crossing, the ferries are equipped with restaurants (on 3 out of 4 ferries), cafeteria, kiosks and WC toilets. (Passengers without cars often make a "double or triple return" journey in the restaurants; for this, a common return ticket is sufficient. Passenger and bicycle passenger tickets are inexpensive compared with longer routes.)
Large cruiseferries sail in the Baltic Sea between Finland, Åland, Sweden, Estonia,and Saint Petersburg, Russia and from Italy to Sardinia, Corsica, Spain and Greece. In many ways, these ferries are like cruise ships, but they can also carry hundreds of cars on car decks. Besides providing passenger and car transport across the sea, Baltic Sea cruiseferries are a popular tourist destination unto themselves, with multiple restaurants, nightclubs, bars, shops and entertainment on board.
The south-west and southern parts of the Baltic Sea has several routes mainly for heavy traffic and cars. The ferry routes of Trelleborg-Rostock SWE-GER, Trelleborg-Travemünde SWE-GER, Trelleborg-Świnoujście SWE-POL, Rødby-Puttgarden DEN-GER, Gedser-Rostock DEN-GER, Gdansk-Karlskrona POL-SWE, and Ystad-Świnoujście SWE-POL are all typical transports ferries. On the longer of these routes, simple cabins are available. On the Trelleborg-Sassnitz SWE-GER route, it also has capacities for the daily night trains between Berlin and Malmö.
In Australia, two Spirit of Tasmania ferries carry passengers and vehicles 300 kilometres across Bass Strait, which separates Tasmania from the Australian mainland. These run overnight but also include day crossings in peak time. Both ferries are based in the northern Tasmanian port city of Devonport and sail to Melbourne.
In New Zealand, ferries connect Wellington in the North Island with Picton in the South Island, linking New Zealand's two main islands. The 92 km route takes three hours, and is run by two companies – government-owned Interislander, and independent Bluebridge.
Hong Kong has the Star Ferry carry passengers across Victoria Harbour and various carriers carrying travellers between Hong Kong Island to outlying islands like Cheung Chau, Lantau Island and Lamma Island.
The Kerala State Water Transport Department (SWTD), opereating under the Ministry of Transport, Government of Kerala, India regulates the inland navigation systems in the Indian state of Kerala and provides inland water transport facilities. It stands for catering to the passenger and cargo traffic needs of the inhabitants of the waterlogged areas of the Districts of Alappuzha, Kottayam, Kollam, Ernakulam, Kannur and Kasargode. SWTD ferry service is also one of the most affordable modes to enjoy the beauty of the scenic Kerala backwaters.
The Penang Ferry Service is the oldest ferry service in Malaysia. The famous ferry service connects Sultan Abdul Halim ferry terminal in Butterworth on Peninsular Malaysia to Raja Tun Uda ferry terminal at Weld Quay in George Town on Penang Island. It has also become a famous tourist attraction among foreigners. Along the way, ferry commuters will get to see the Penang Bridge and also the skyline of George Town and Butterworth.
Due to the numbers of large freshwater lakes and length of shoreline in Canada, many provinces and territories have ferry services. BC Ferries carries travellers between Vancouver Island and the British Columbia mainland on the country's west coast. This ferry service operates to other islands including the Gulf Islands and the Queen Charlotte Islands. Canada's east coast has been home to numerous inter and intra provincial ferry and coastal services, including a large network operated by the federal government under CN Marine and later Marine Atlantic. Private and publicly owned ferry operations in eastern Canada include Marine Atlantic, serving the island of Newfoundland, as well as Bay, NFL, CTMA, Coastal Transport, and STQ to name but a few. Canadian waters in the Great Lakes once hosted numerous ferry services, however these have been reduced to those offered by Owen Sound Transportation and several smaller operations. There are also several commuter passenger ferry services operated in major cities, such as Metro Transit in Halifax, Toronto Island Ferry in Toronto and SeaBus in Vancouver.
Washington State Ferries operates the most extensive ferry system in the United States, with ten routes on Puget Sound and the Strait of Juan de Fuca serving terminals in Washington and Vancouver Island. In 2012, Washington State Ferries carried 10 million vehicles and 22 million passengers.
The Staten Island Ferry in New York City, sailing between the boroughs of Manhattan and Staten Island, is the nation's single busiest ferry route by passenger volume. New York City also has a network of smaller ferries, or water taxis, that shuttle commuters along the Hudson River from locations in New Jersey and Northern Manhattan down to the midtown, downtown and Wall Street business centers.
The New Orleans area also has many ferries in operation that carry both vehicles and pedestrians. Most notable is the Algiers Ferry. This service has been in continuous operation since 1827 and is one the oldest operating ferries in North America.
Vehicle-carrying ferry services between mainland Cape Cod and the islands of Martha's Vineyard and Nantucket are operated by The Woods Hole, Martha's Vineyard and Nantucket Steamship Authority, which sails year-round between Woods Hole and Vineyard Haven as well as Hyannis and Nantucket. Seasonal service is also operated from Woods Hole to Oak Bluffs from Memorial Day to Labor Day. As there are no bridges or tunnels connecting the islands to the mainland, The Steamship Authority ferries in addition to being the only method for transporting private cars to or from the islands, also serves as the only link by which heavy freight and supplies such as food and gasoline can be trucked to the islands. Additionally, Hy-Line Cruises operates high speed catamaran service from Hyannis to both islands, as well as traditional ferries, and several smaller operations run seasonal passenger only service primarily geared towards tourist day-trippers from other mainland ports, including New Bedford, (New Bedford Fast Ferry) Falmouth, (Island Queen ferry and Falmouth Ferry) and Harwich (Freedom Cruise Line).
The San Francisco Bay Area has several ferry services, such as the Blue & Gold Fleet, connecting with cities as far as Vallejo. The majority of ferry passengers are daily commuters and tourists. A ferry serves Angel Island (which also accepts private craft). The only way to get to Alcatraz is by ferry.
Until the completion of the Mackinac Bridge in the 1950s, ferries were used for vehicle transportation between the Lower Peninsula of Michigan and the Upper Peninsula of Michigan, across the Straits of Mackinac in the United States. Ferry service for bicycles and passengers continues across the straits for transport to Mackinac Island, where motorized vehicles are almost completely prohibited. This crossing is made possible by three ferry lines, Arnold Transit Company, Shepler's Ferry, and Star Line Ferry.
Ferry designs depend on the length of the route, the passenger or vehicle capacity required, speed requirements and the water conditions the craft must deal with.
Double-ended ferries have interchangeable bows and sterns, allowing them to shuttle back and forth between two terminals without having to turn around. Well-known double-ended ferry systems include the Staten Island Ferry, Washington State Ferries, Star Ferry, several boats on the North Carolina Ferry System, and the Lake Champlain Transportation Company. Most Norwegian fjord and coastal ferries are double-ended vessels. Some ferries in Sydney, Australia and British Columbia are also double-ended. In 2008, BC Ferries launched three of the largest double-ended ferries in the world.
Hydrofoils have the advantage of higher cruising speeds, succeeding hovercraft on some English Channel routes where the ferries now compete against the Eurotunnel and Eurostar trains that use the Channel Tunnel. Passenger-only hydrofoils also proved a practical, fast and relatively economical solution in the Canary Islands but were recently replaced by faster catamaran "high speed" ferries that can carry cars. Their replacement by the larger craft is seen by critics as a retrograde step given that the new vessels use much more fuel and foster the inappropriate use of cars in islands already suffering from the impact of mass tourism.
Hovercraft were developed in the 1960s and 1970s to carry cars. The largest was the massive SR.N4 which carried cars in its centre section with ramps at the bow and stern between England and France. The hovercraft was superseded by catamarans which are nearly as fast and are less affected by sea and weather conditions. Only one service now remains, a foot passenger service between Portsmouth and the Isle of Wight run by Hovertravel.
Catamarans are normally associated with high-speed ferry services. Stena Line operates the largest catamarans in the world, the Stena HSS class, between the United Kingdom and Ireland. These waterjet-powered vessels, displacing 19,638 tonnes, are larger than most catamarans and can accommodate 375 passenger cars and 1,500 passengers. Other examples of these super-sizer catamarans are found in the Brittany Ferries fleet with the Normandie Express and the Normandie Vitesse.
Roll-on/roll-off ferries (RORO) are large, conventional ferries named for the ease by which vehicles can board and leave.
Fast RoPax ferries are conventional ferries with a large garage intake and a relatively large passenger capacity, with conventional diesel propulsion and propellers that sail over 25 knots (46 km/h; 29 mph). Pioneering this class of ferries was Attica Group, when it introduced Superfast I between Greece and Italy in 1995 through its subsidiary company Superfast Ferries. Cabins, if existent, are much smaller than those on cruise ships.
This type of ferry allows vehicles to load from the "side". The vehicle platform can be turned. When loading, the platform is turned sideways to allow sideways loading of vehicles. Then the platform is turned back, in line with the vessel, and the journey across water is made.
Pontoon ferries carry vehicles across rivers and lakes and are widely used in less-developed countries with large rivers where the cost of bridge construction is prohibitive. One or more vehicles are carried on a pontoon with ramps at either end for vehicles to drive on and off. Cable ferries (next section) are usually pontoon ferries, but pontoon ferries on larger rivers are motorised and able to be steered independently like a boat.
A Train ferry is a ship designed to carry railway vehicles. Typically, one level of the ship is fitted with railway tracks, and the vessel has a door at the front and/or rear to give access to the wharves.
Foot ferries are small craft used to ferry foot passengers, and often also cyclists, over rivers. These are either self-propelled craft or cable ferries. Such ferries are for example to be found on the lower River Schelde in Belgium and in particular the Netherlands. Regular foot ferry service also exists in the capital of the Czech Republic, Prague, and across the Yarra River in Melbourne, Australia at Newport. Restored, expanded ferry service in the Port of New York and New Jersey uses boats for pedestrians only.
Very short distances may be crossed by a cable or chain ferry, which is usually a pontoon ferry (see above), where the ferry is propelled along and steered by cables connected to each shore. Sometimes the cable ferry is human powered by someone on the boat. Reaction ferries are cable ferries that use the perpendicular force of the current as a source of power. Examples of a current propelled ferry are the four Rhine ferries in Basel, Switzerland. Cable ferries may be used in fast-flowing rivers across short distances.
Free ferries operate in some parts of the world, such as at Woolwich in London, England (across the River Thames); in Amsterdam, Netherlands (across the IJ waterway); in New York Harbor, connecting Manhattan to Staten Island; along the Murray River in South Australia, and across many lakes in British Columbia. Many cable ferries operate on lakes and rivers in Canada, among them a cable ferry that charges a toll operates on the Rivière des Prairies between Laval-sur-le-Lac and Île Bizard in Quebec, Canada.
In the 1950s and 1960s, travel on an "air ferry" was possible—aeroplanes, often ex-military, specially equipped to take a small number of cars in addition to "foot" passengers. These operated various routes including between the United Kingdom and Continental Europe. Companies operating such services included Channel Air Bridge, Silver City Airways, and Corsair.
The term is also applied to any "ferrying" by air, and is commonly used when referring to airborne military operations.
Ferry boats often dock at specialized facilities designed to position the boat for loading and unloading, called a ferry slip. If the ferry transports road vehicles or railway carriages there will usually be an adjustable ramp called an apron that is part of the slip. In other cases, the apron ramp will be a part of the ferry itself, acting as a wave guard when elevated and lowered to meet a fixed ramp at the terminus — a road segment that extends partially underwater.
A contender as oldest ferry in continuous operation is the Mersey Ferry from Liverpool to Birkenhead, England. In 1150, the Benedictine Priory at Birkenhead was established. The monks used to charge a small fare to row passengers across the estuary. In 1330, Edward III granted a charter to the Priory and its successors for ever: "the right of ferry there… for men, horses and goods, with leave to charge reasonable tolls". However there may have been a short break following the Dissolution of the monasteries.
Another claimant as the oldest ferry service in continuous operation is the Rocky Hill - Glastonbury Ferry, running between the towns of Rocky Hill and Glastonbury, Connecticut. Established in 1655, the ferry has run continuously since, only ceasing operation every winter when the river freezes over. A long running salt water ferry service is the Halifax/Dartmouth ferry, running between the cities of Halifax and Dartmouth, Nova Scotia, which has run year-round since 1752, and is currently run by the region's transit authority, Metro Transit. However the Mersey Ferry predates it as the oldest salt water ferry.
Two of the world's largest ferry systems are located in the Strait of Georgia, in the Canadian province of British Columbia, and Puget Sound, in the U.S. state of Washington. BC Ferries in British Columbia operates 36 vessels, visiting 47 ports of call, while Washington State Ferries owns 28 vessels, travelling to 20 ports of call around Puget Sound. On the west coast of Scotland, Caledonian MacBrayne operate a network calling at 50 ports using a fleet of 29 vessels, 9 of which are 80m or longer. This includes a high proportion of lifeline services to island communities and as such most of the routes are heavily subsidised by the government.
Sydney Ferries in Sydney, Australia operates 31 passenger ferries in Port Jackson (Sydney Harbour), carrying 18 million passengers annually. It operates catamarans and other types of ferries on these routes, with the most famous likely being the Circular Quay-Manly route. Between 1938 and 1974 this route operated the South Steyne, billed at the time as the largest and fastest ferry of its type. Sydney Ferries became an independent corporation owned by the government in 2004.
Metrolink Queensland operates 21 passenger ferries on behalf of Brisbane City Council, 12 being single-hulled ferries and 9 CityCats (catamarans), along the Brisbane River from the University of Queensland through the city to Brett's Wharf.
The gas-powered Luciano Federico L operated by Montevideo-based Buquebus, holds the Guinness World Record for the fastest car ferry boat in the world, in service between Montevideo, Uruguay and Buenos Aires, Argentina: its maximum speed, achieved in sea trials, was 60.2 knots (111.5 km/h; 69.3 mph). It can carry 450 passengers and 52 cars along the 110-nautical-mile (200 km; 130 mi) route.
The contributions of ferry travel to climate change have received less scrutiny than land and air transport, and vary considerably according to factors like speed and the number of passengers carried. Average carbon dioxide emissions by ferries per passenger-kilometre seem to be 0.12 kg (4.2 oz). However, 18-knot ferries between Finland and Sweden produce 0.221 kg (7.8 oz) of CO2, with total emissions equalling a CO2 equivalent of 0.223 kg (7.9 oz), while 24–27-knot ferries between Finland and Estonia produce 0.396 kg (14.0 oz) of CO2 with total emissions equalling a CO2 equivalent of 0.4 kg (14 oz).
With the price of oil at high levels, and with increasing pressure from consumers for measures to tackle global warming, a number of innovations for energy and the environment were put forward at the Interferry conference in Stockholm. According to the company Solar Sailor, hybrid marine power and solar wing technology are suitable for use with ferries, private yachts and even tankers.
