INLAND ONLY When power-driven vessels are in a crossing situation, what does one short blast by either vessel indicate?

Correct Answer: Option C — "I intend to leave you on my port side"

33 CFR 83.34(a) establishes that one short blast signifies an intention to alter course to starboard. By signaling this, the vessel communicates its plan to pass in a way that leaves the other vessel on its port side, facilitating safe navigation during a crossing encounter.
