What should a vessel do if there is any doubt about potential risk of collision?

In situations where there is any doubt about the potential risk of collision, the prudent course of action is to consider that a risk does exist. This approach aligns with the principles outlined in the COLREGs, specifically Rule 2, which emphasizes that all mariners must use caution and good seamanship to avoid collisions. By acknowledging the possibility of a risk, a vessel can take the necessary steps to assess the situation further and implement safety measures.

This method encourages vigilance and proactive safety measures, rather than becoming complacent or overly confident about the absence of risk. When a vessel considers that a risk is present, it empowers the crew to act with caution, whether that means adjusting course, reducing speed, or preparing to take evasive action as necessary. Ultimately, safety should always be prioritized, and this approach helps to prevent accidents that may arise from misjudgment or overconfidence.
