When two sailboats approach each other with the wind on the same side, which vessel is the stand-on vessel?

When two sailboats approach each other with the wind coming from the same side, the vessel that is to leeward is considered the stand-on vessel. This means that it has the right of way, and the other vessel must take action to avoid a collision.

In sailing terminology, “leeward” refers to the side away from the wind, while “windward” refers to the side facing the wind. The leeward vessel is generally in a more favorable position because it is already moving with the wind, and any change in course would likely affect it more negatively than the windward vessel. Therefore, the windward vessel must give way to the leeward vessel, hence designating the leeward vessel as the stand-on vessel.

This rule is essential for maintaining safety and preventing collisions when multiple sailing vessels are navigating in close proximity on the water.
