The primary differences between barges and narrowboats lie in their size, design, and intended use. Barges are typically larger, broader, and heavier vessels with a flat-bottomed hull. They are designed for carrying heavy cargo, and their size allows them to transport substantial loads. Narrowboats, as the name suggests, are narrower and more streamlined than barges. They have a distinctive long, narrow shape and a deeper draft relative to their size. Due to the width of the canals in Wales, Black Prince offers narrowboat holidays as opposed to barge holidays in this area.
