In a crossing situation, which vessel is the stand-on vessel?

• A. The vessel that has the other vessel on its port side.
• B. The vessel that has the other vessel on its starboard side.
• C. The faster vessel.
• D. The vessel that is closer to the other.

Answer: (B)

In a crossing situation, the stand-on vessel is the one that has the other vessel on its starboard side. The stand-on vessel should maintain its course and speed, while the other vessel (the give-way vessel) must take early action to avoid collision if needed. The key cue is the relative bearing: if you see the other vessel over your right-hand side (starboard), you are the stand-on vessel. The faster or closer state does not determine stand-on status.
