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 C — The tug should put a stern line up, leading ahead on the ship.

When an assisting tug is required to hold a ship's bow off while stemming a current, a stern line leading ahead on the ship transfers the longitudinal thrust safely. This orientation enables the tug to push or pull efficiently without tripping.
