BOTH INTERNATIONAL & INLAND If two sailing vessels are running free with the wind on the same side, which one must keep clear of the other?

Correct Answer: Option B — The one to windward

Rule 12(a)(i) states that when two sailing vessels have the wind on the same side, the vessel which is to windward shall keep out of the way of the vessel which is to leeward. The leeward vessel is the stand-on vessel because she is less likely to be 'pinned' by the wind.
