BOTH INTERNATIONAL & INLAND Vessel "A" is overtaking vessel "B" as shown in illustration D017RR below. In this situation which of the following describes vessel "B"?

Correct Answer: Option A — vessel B is the stand-on vessel

Rule 13 defines an overtaking vessel as one approaching from more than 22.5 degrees abaft the beam. The overtaking vessel is the give-way vessel, while the vessel being overtaken is the stand-on vessel. Vessel B, being overtaken, must maintain its course and speed as required by Rule 17.
