BOTH INTERNATIONAL & INLAND Sailing vessels are considered the stand-on vessel over power-driven vessels, except in which of the following situations?

Correct Answer: Option D — when they are the overtaking vessel

Rule 18(a) defines the hierarchy of vessels, but Rule 13 (Overtaking) overrides all other steering and sailing rules. Regardless of the vessel type, any vessel overtaking another must keep out of the way of the vessel being overtaken, as the overtaking vessel is always the give-way vessel.
