Ferry transportation involves the use of boats or ships to carry passengers, vehicles, and goods across bodies of water. Ferries are commonly used to connect islands, cross rivers, or link coastal cities, providing an essential service where bridges or tunnels are not available. They operate on scheduled routes and can vary in size, from small boats to large vessels. Ferries are an important part of public transportation systems in many regions, such as the Washington State Ferries in the United States or the Staten Island Ferry in New York City. They help reduce road congestion and offer scenic views during the journey, making travel more enjoyable.
