Which rule pertains to the actions when overtaking another vessel?

The correct answer pertains to Rule 13, which specifically addresses the actions required when a vessel is overtaking another. According to Rule 13, a vessel that is overtaking another must keep out of the way of the vessel that is being overtaken. This rule is essential for preventing collisions and ensuring safety on the water by designating clear responsibilities for vessels engaged in overtaking maneuvers.

In practice, when a vessel is overtaking another, it is important for the overtaking vessel to be aware of its position relative to the other vessel and to maneuver accordingly to avoid potential hazards. Failing to comply with this rule could lead to dangerous situations and is a critical aspect of safe navigation.

The other rules mentioned, although they address various navigation situations, do not specifically cover overtaking. For example, Rule 9 pertains to narrow channels, Rule 14 describes head-on situations, and Rule 15 addresses crossing situations. Each rule has its specific context, but for overtaking maneuvering, Rule 13 is definitive and crucial.
