What should a vessel do if it identifies a risk of collision when crossing another vessel?

When a vessel identifies a risk of collision while crossing another vessel, it is crucial to assess the situation carefully. The correct approach involves determining whether the give-way vessel is taking appropriate action to prevent a collision. This assessment is fundamental to ensuring safe navigation, as it allows the observing vessel to understand the intentions and actions of the other vessel involved.

Engaging in this evaluation is consistent with the principles outlined in the International Regulations for Preventing Collisions at Sea (COLREGs), which emphasize the obligation of vessels to take action in good time to avoid collisions. By observing whether the give-way vessel is responding appropriately, the navigating vessel can decide the best course of action, which may include altering course or speed, rather than making hasty maneuvers without clear awareness of the other vessel's situation.

Addressing the other options, waiting for the other vessel to maneuver can lead to delays in taking necessary action and may contribute to the risk of collision. Changing course immediately without a clear assessment may result in an unexpected collision course or other navigational hazards. Maintaining current course and speed, if there is a risk of collision, does not adhere to the obligation to take positive actions in a timely manner to avoid such situations.
