When two power-driven vessels are crossing, the vessel which has the other to starboard must keep out of the way if what?

• A. The vessel on port side
• B. The situation involves risk of collision
• C. The other is not under command
• D. The other signals

Answer: (B)

In a crossing situation between power-driven vessels, the vessel that has the other vessel on its starboard side is the give-way vessel and must keep out of the other vessel’s way if there is a risk of collision. This means you should take early and substantial action to avoid a close-quarters situation whenever you detect that the other vessel is approaching from your starboard side and a collision could occur. The stand-on vessel would maintain course unless the give-way vessel fails to take action or the risk of collision increases. So the key idea is that action is required whenever there is a risk of collision; it’s not about which side the other vessel is on in isolation, nor about under-command status or signals.
