When must a powered vessel keep clear of a sailing vessel?

A powered vessel must keep clear of a sailing vessel when the sailing vessel is under sail because sailing vessels have the right of way over powered vessels in many navigation situations. This rule is established to protect the sailing vessel’s ability to maneuver and maintain its course, as it relies on wind power for propulsion.

In circumstances where a sailing vessel is actively navigating under its sails, it presents specific challenges and limitations in terms of maneuverability compared to a powered vessel. Maintaining a safe distance helps to prevent potential collisions and allows the sailing vessel to operate safely.

In contrast, scenarios such as the sailing vessel being aground or being overtaken by the powered vessel may not apply the same right of way rules. If the sailing vessel is aground, it is no longer navigating and the powered vessel can proceed without concern. Additionally, while a powered vessel should always be cautious when overtaking, the core rule remains in favor of the sailing vessel under sail, recognizing its operational status as a vessel in motion.
