You You are docking a ship with a single-screw tug assisting on your starboard bow. How should the tug be tied up if you are anticipating that she will have to hold your bow off while you stem the current?

Correct Answer: Option A — The tug should put a stern line up, leading ahead on the ship.

A stern line leading ahead on the ship allows the tug to exert a pulling force that keeps the ship's bow off the dock while the ship's engines are used to stem the current. This configuration provides the tug with the mechanical advantage needed to maintain a safe standoff distance.
