How should a vessel respond when another vessel signals uncertainty?

When another vessel signals uncertainty, the best course of action is to slow down and be prepared to stop. This response is crucial because it allows for a safer navigational environment, ensuring that both vessels can assess the situation more clearly. By slowing down, the captain maintains control of their own vessel and prevents any unforeseen collisions that may occur if both vessels assume the other will adhere to navigational rules.

Signal uncertainty can indicate that the other vessel may not be certain of their course or speed, or might be waiting for the opportune moment to make a decision. Slowing down provides a buffer for reaction time and allows for more effective communication, ensuring the actions taken are in compliance with maritime safety regulations.

Proceeding at full speed could lead to an increased risk of collision, as it does not acknowledge the uncertainty being signaled. Continuing on the current path without caution is similarly reckless and does not consider the potential for miscommunication or hazardous situations. Changing course without warning could also result in confusion or another collision, as it does not provide the other vessel with appropriate information about your intentions.

By preparing to slow down and remain vigilant, you enhance safety for both vessels involved.
