The image shows a tugboat, a small but powerful working ship designed to tow or pull up other ships in ports or on rivers. Tugs usually have a short and wide hull, which provides them with stability and maneuverability. The figure shows how the tugboat stands on the water, with several windows on the captain's bridge and a smoke pipe through which smoke from the working engine escapes. This is an ideal coloring option, allowing children to develop artistic skills as well as learn more about seagoing vessels and their purpose.
