How can vessels at anchor maintain safe navigation in a traffic separation scheme?

Vessels at anchor in a traffic separation scheme must prioritize safety to ensure they do not pose a risk to navigation and other vessels. One of the primary ways they can achieve this is by displaying appropriate lights and signals. This practice is essential for visibility, especially in conditions of reduced light or visibility, allowing other vessels to recognize that an anchored vessel is present and identify its position.

Displaying lights and signals is a requirement under the Navigation Rules, which are designed to prevent collisions and enhance safe navigation. This visibility is crucial to ensure that vessels passing through the traffic separation scheme can safely navigate around the anchored vessel without incident.

In contrast, remaining stationary without lights would endanger the safety of navigation as other vessels may not be aware of the anchored vessel's presence. Similarly, simply moving frequently does not provide assurance of safety in navigation and can create confusion in a traffic separation scheme. Lastly, displaying only sound signals is insufficient for safe navigation, particularly at night or during low visibility conditions where visual signals are critical. Therefore, the requirement to display appropriate lights and signals is integral to maintaining safety in navigational scenarios like a traffic separation scheme.
