Astern Tug

An astern tug refers to a tugboat that maneuvers a larger vessel from behind it, often pulling it in the reverse direction. This technique is used in situations where the larger ship needs assistance navigating tight spaces, such as ports or narrow waterways. The tugboat helps control the larger vessel's movements, ensuring safer and more precise docking or undocking. By positioning itself astern, the tug can effectively manage the vessel’s direction and speed, enhancing safety during complicated maneuvers in challenging environments.
