Which rule addresses the risk of collision?

In the context of the COLREGs, Rule 7 specifically addresses the risk of collision by outlining the responsibility of all vessels to assess whether such a risk exists and to take appropriate measures to avoid collisions. This rule emphasizes that vessels should use all available means, including radar, visual sightings, and other navigational aids, to determine if there is a risk of collision. It states that when there is any doubt about whether a risk exists, it must be assumed that it does. The rule further stresses the importance of conducting a thorough assessment of the situation to ensure safe navigation and to take action well in advance if a risk is detected.

The importance of this rule lies in its proactive approach, encouraging mariners to actively engage in monitoring their environment and to implement preventive measures, rather than reacting to potential collisions after they have occurred. This focus on risk assessment is crucial for maintaining safety at sea.
