In a crossing with risk of collision, which vessel has the obligation to keep out of the way when the other is on its starboard side?

• A. The vessel with the other to starboard keeps out of the way
• B. The vessel on the other side yields
• C. Both must slow down
• D. Neither must take action

Answer: (A)

In a crossing situation, the key rule is that the vessel which has another vessel on its starboard side must keep out of the way. If you see another vessel to your right, you’re the give-way vessel and you should take early and substantial action to avoid a collision. The other vessel, which has you on its port side, is the stand-on vessel and should maintain its course and speed unless danger requires otherwise. So, when the other is on your starboard, you are obligated to maneuver to keep well clear.
