BOTH INTERNATIONAL & INLAND A sailing vessel is overtaking a tug and tow as shown in illustration D043RR below. Which statement is correct?

Correct Answer: Option A — The tug is the stand-on vessel because it is being overtaken.

Rule 13(a) dictates that any vessel overtaking any other shall keep out of the way of the vessel being overtaken. Regardless of the fact that the overtaking vessel is under sail, the rule is absolute: the vessel being overtaken is the stand-on vessel and must maintain course and speed.
