What does Rule 5 of COLREGs require vessels to do?

Rule 5 of the COLREGs mandates that all vessels maintain a proper look-out by sight and hearing, as well as by all available means appropriate to the prevailing circumstances and conditions. This requirement is crucial for safety on the water, as it enables vessels to detect other vessels, navigational hazards, and changing conditions in a timely manner.

Maintaining a proper look-out helps in preventing collisions by ensuring that crew members are vigilant and aware of their surroundings. This includes using visual observation and auditory cues, as well as navigation instruments such as radar if required. The emphasis on a comprehensive look-out underscores the importance of situational awareness in maritime navigation.

Establishing this lookout is foundational to making informed decisions regarding navigation and maneuvering in order to avoid potential dangers at sea. Hence, the requirement to maintain a proper look-out is a critical element in the COLREGs aimed at ensuring maritime safety.
