Canal transport is a form of transportation that utilizes canals, such as rivers, lakes, and man-made waterways. Two common forms of canal transport are gondolas and barges. Gondolas are small, flat-bottomed boats that are propelled by a single oar or pole. They are typically used for sightseeing and leisure activities. Barges are larger vessels that are usually pushed or towed by a motorized boat. They are commonly used to transport goods and materials over long distances.
