What is required of every vessel regarding look-out?

Every vessel is required to maintain a proper look-out by sight, hearing, and other means to ensure safe navigation and to avoid collisions. This requirement is a fundamental principle under the COLREGs, specifically Rule 5, which emphasizes the importance of being aware of the surrounding environment at all times. A proper look-out enables a vessel to detect other vessels, navigational hazards, and changing conditions, thereby allowing for timely reactions to potential dangers.

The mention of using multiple senses, such as sight and hearing, acknowledges that not all hazards can be detected visually, especially in varying weather conditions or at night. Reliance solely on visual observations would limit situational awareness and increase the risk of accidents.

The other options are limited in scope; suggesting that look-out is only necessary in foggy conditions ignores the need for vigilance at all times, while stating that only the captain needs to maintain a look-out overlooks the shared responsibility of all crew members. This holistic approach to the look-out aligns with the aim of maritime safety, ensuring that everyone on board contributes to the vessel’s awareness and navigational safety.
