In a crossing situation involving two power-driven vessels, which vessel must keep out of the way?

In a crossing situation between two power-driven vessels, the vessel that is on its own port side is required to give way. This is based on the navigational rules that dictate the right of way during such encounters. When two vessels approach each other, the general rule is that the vessel that sees another on its port side must keep clear, as that vessel is operating on the starboard side of the encounter. This creates a standard of navigation that helps to prevent collisions and ensures safety on the water.

In this scenario, since the answer points to the vessel on its own port side needing to yield, it aligns with these established maritime rules, which emphasize the importance of situational awareness and adherence to navigation protocols. Knowing which side has the obligation to yield is crucial for safe and effective maneuvering between vessels.
