INLAND ONLY A power-driven vessel crossing on the Western Rivers has the right of way over which vessels?

Correct Answer: Option D — None of the above

Rule 15 does not grant inherent right-of-way to vessels based on their direction of travel on Western Rivers. While local customs or Inland Rule 9 (Narrow Channels) may influence navigation, no specific rule mandates that a power-driven vessel has right-of-way over others simply due to ascending or descending the river.
