Passenger ferries are boats or ships designed to carry people across bodies of water, such as rivers, lakes, or seas. They are commonly used in areas where bridges or tunnels are not available, providing a vital link between communities. Ferries can vary in size, from small vessels accommodating a few dozen passengers to large ships that can carry hundreds or even thousands. These ferries often operate on a regular schedule, allowing passengers to travel for work, leisure, or tourism. Some well-known examples include the Staten Island Ferry in New York and the BC Ferries in British Columbia, Canada, which connect various islands to the mainland.
