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

• A. The vessel which has the other to port
• B. The larger vessel
• C. The vessel which has the other to starboard
• D. The faster vessel

Answer: (C)

On crossing scenarios between power-driven vessels, the vessel that has the other vessel on its starboard side must keep out of the way. This means if you see the other vessel to your right (starboard), you are the give-way vessel and should adjust your course or speed to avoid a collision. The stand-on vessel is the one with the other vessel on its port side, which should maintain its course unless the risk of collision increases and action is needed. Size and speed don’t change who yields; the decision is based on the relative bearing. In this situation, since the other vessel is on your starboard, you must take early, substantial action to avoid crossing paths.
