When two power-driven vessels are crossing, which is the stand-on vessel?

• A. The vessel on the port side of the other vessel
• B. The vessel which is to starboard of the other vessel
• C. The faster vessel
• D. The larger vessel

Answer: (B)

In a crossing situation between two power-driven vessels, the stand-on vessel is the one that has the other vessel on its starboard side. This means the other vessel is on its port side and must take early action to avoid, while the stand-on vessel should maintain course and speed unless collision risk requires otherwise. The starboard-side positioning gives that vessel the right of way under the collision regulations. The larger or faster vessel isn’t automatically stand-on; it’s determined by which vessel is on the other’s starboard.
