What should a vessel do if it is unsure of another vessel's intentions?

When a vessel is unsure of another vessel's intentions, it should take precautionary measures to avoid a collision. This practice aligns with the Rules of the Road, which prioritize safety and the prevention of maritime accidents. By taking precautions, the vessel can ensure that it is prepared for any unexpected maneuvers by the other vessel, which helps to mitigate risk and maintain safe navigation.

Taking precautionary measures can include altering course, reducing speed, or even stopping if the situation warrants it. This proactive approach allows the vessel to remain in control of the situation and reduces the potential for miscommunication or misunderstanding that could lead to a dangerous encounter on the water.

While maintaining speed or assuming the other vessel will maintain its course may seem like viable options, these approaches do not actively address the uncertainty at hand. They could lead to a situation where a collision is likely if the other vessel decides to change course unexpectedly. Similarly, signaling the other vessel could provide clarity, but it may not always be feasible or effective in all situations, particularly in busy waterways or poor visibility conditions. Thus, taking precautionary measures is the most reliable and prudent course of action when in doubt about another vessel’s intentions.
