Which tug arrangement is generally used for tighter turns?

The bow tow arrangement is generally preferred for making tighter turns because it allows for better maneuverability and control of the vessel being towed. In this configuration, the tugboat is positioned at the front of the tow, which provides more direct steering capabilities. This positioning allows the tug to effectively lead the tow through turns, as the bow of the tug can pull the tow into the desired direction.

When making turns, particularly at a sharper angle, having the tug at the bow reduces the risks associated with dragging the stern of the vessel being towed in the opposite direction. The bow tow also helps to keep the tow aligned with the tug's direction, reducing the potential for sideways drift and making the overall turning radius smaller. This is especially advantageous in restricted waters or when navigating through narrow channels.

In contrast, other tow arrangements, such as the stern tow or side tow, may provide less maneuverability and can complicate turning dynamics, potentially requiring more space to execute a turn. The parallel tow also does not offer the same degree of directional control, which is crucial during tight maneuvers.
