What should a vessel do to keep clear of another vessel?

The most effective way for a vessel to keep clear of another vessel is to take early and substantial action to keep well clear. This proactive approach aligns with the principles outlined in the International Regulations for Preventing Collisions at Sea (COLREGs), which emphasize the importance of avoiding situations that could lead to close quarters or potential collisions.

Taking early and substantial action means identifying potential conflicts well in advance and maneuvering accordingly—this could involve altering course, changing speed, or employing both tactics to ensure a safe distance is maintained. By doing so, a vessel reduces the risk of misunderstanding or miscommunication that might arise from more reactive measures.

In situations where signals from other vessels are present, while they are important to acknowledge and follow, relying solely on them without preemptive action might not sufficiently ensure safety. Waiting until a collision seems imminent is contrary to the COLREGs' emphasis on prevention and can lead to dangerous scenarios due to late responses. Thus, taking early and substantial action establishes a clear standard for safe navigation and responsible seamanship, which is why this approach is the preferred method for keeping clear of other vessels.
