A ferryboat is a type of boat or ship designed to carry passengers, vehicles, and goods across a body of water. They are commonly used to connect islands, cross rivers, or link coastal areas. Ferryboats can vary in size and capacity, accommodating everything from small groups to large numbers of vehicles and people. Ferry services are often an essential part of public transportation systems in many regions. They provide a convenient and efficient way to travel, especially where bridges or tunnels are not available. Some well-known ferry routes include those in San Francisco Bay and the Sydney Harbour.
