Under Rule 29, how should vessels respond in crossing situations to minimize collision risks?

Under Rule 29 of the COLREGs, vessels are required to take measures to minimize the risks of collision during crossing situations. This rule emphasizes the importance of actively assessing the situation on the water and taking appropriate actions to avoid potential collisions. A responsible navigational practice involves not only assessing the relative positions and movements of other vessels but also being proactive in implementing measures to prevent close-quarters situations that could lead to collisions.

Maintaining speed and course without adjustments may not account for the dynamic nature of maritime traffic, where vessels are continuously moving and their paths may intersect. While signaling the other vessel can be helpful for communication, it does not replace the responsibility to take action to avoid collisions. Similarly, changing direction without notice could lead to confusion and increase the risk of collision, especially if the other vessel is unaware of the change. Therefore, the principle of taking measures to minimize risks reflects the core of safe navigation and emphasizes proactive decision-making in crossing situations.
