INLAND ONLY You are on a power-driven vessel "I" as shown in illustration D036RR below. Vessel "II" is a power-driven vessel engaged in fishing that will pass within 1/2 a mile of your vessel. Which action should you take?

Correct Answer: Option A — Sound one short blast and await response from the fishing vessel.

Inland Rule 34(a) requires power-driven vessels in sight of one another to sound whistle signals when maneuvering. Since the vessels are within half a mile, they are in a meeting or crossing situation requiring communication. One short blast indicates an intention to leave the other on the port side.
