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 C — The one to windward

Rule 12(a)(ii) governs sailing vessels with 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. This ensures the leeward vessel maintains its maneuverability and avoids being blanketed by the windward vessel's sails.
