When two sailing vessels are approaching each other with a risk of collision, determining which vessel must take action is essential for maintaining safety at sea. To avoid confusion, the International Regulations for Preventing Collisions at Sea (COLREGs) provide clear guidance through Rule 12.
Rule 12 applies specifically to sailing vessels and establishes responsibilities based on the direction from which the wind is received.
Wind on Different Sides
When two sailing vessels have the wind on different sides, the vessel with the wind on the port side must keep out of the way of the other vessel. In this situation, the vessel with the wind on the starboard side is considered the stand-on vessel and should maintain her course and speed.
Wind on the Same Sides
When both vessels have the wind on the same side, the windward vessel must keep out of the way of the leeward vessel. The leeward vessel becomes the stand-on vessel, while the windward vessel is required to maneuver to avoid the risk of collision.
Why Rule 12 Matters
The purpose of Rule 12 is to establish clear responsibilities between sailing vessels and eliminate uncertainty during encounters at sea. By providing simple and universally recognized rules, it helps mariners make timely decisions and significantly reduces the risk of collision.
Understanding and applying Rule 12 is a fundamental part of seamanship and an important step toward safer navigation for both recreational sailors and professional mariners.
