INLAND ONLY Your vessel is crossing a river on the Great Lakes System. A power-driven vessel is ascending the river, crossing your course from port to starboard. Which statement is TRUE?

Correct Answer: Option A — The vessel ascending the river has the right of way.

33 CFR 83.15(a) dictates that on the Great Lakes, Western Rivers, or other specified waters, a vessel ascending a river against the current shall not impede a vessel descending the river. Therefore, the ascending vessel must yield, granting the descending vessel the right of way.
