How should a vessel act when directed to keep out of the way of another vessel?

When a vessel is directed to keep out of the way of another vessel, it is crucial for safety and navigation that it takes early and substantial action to ensure it remains well clear. This approach minimizes the risk of collision and demonstrates adherence to maritime regulations, specifically the International Regulations for Preventing Collisions at Sea (COLREGs).

Taking early action allows the vessel to signal its intentions clearly and provides sufficient time for both vessels to maneuver safely. The term "substantial" emphasizes that the alteration of course or speed must be significant enough to avoid any uncertainty regarding the vessel's movements. By acting decisively, the vessel fosters better situational awareness among nearby mariners and avoids potential misinterpretation of its intentions or actions.

In maritime navigation, particularly under COLREGs, maintaining a proper lookout and acting to prevent collision are paramount responsibilities of the vessel's crew. The directive to keep out of the way mandates proactive measures rather than passive observance, enhancing overall navigational safety.
