Cable ferries are boats that transport people and vehicles across rivers or lakes using a cable system. They are anchored at both ends and move along the cable, which is usually attached to a fixed point on the shore. This method allows for efficient crossing without the need for a bridge. These ferries are often used in areas where building a bridge is impractical or too expensive. They can operate in various weather conditions and are a reliable means of transportation for local communities. Examples of cable ferries can be found in regions like Canada and New Zealand.
