BOTH INTERNATIONAL & INLAND If a sailing vessel with the wind on the port side sees a sailing vessel to windward and cannot tell whether the other vessel has the wind on the port or starboard side, she shall __________.

Correct Answer: Option D — keep out of the way of the other vessel

COLREG Rule 12(a)(i) specifies that when both sailing vessels have the wind on the same side, the vessel to windward shall keep out of the way of the vessel to leeward. If unable to determine the other's wind side, standard seamanship demands treating oneself as burdened.
