Which action should not be taken while operating a vessel in congested waters?

In congested waters, it is crucial to avoid actions that compromise safety or situational awareness. Ignoring the presence of smaller craft is particularly detrimental because these vessels may be more maneuverable and can pose unexpected risks to larger ships. The dynamics of congested waterways often mean that traffic is unpredictable, and smaller craft can change course more easily or may not adhere strictly to navigation rules.

Continuous monitoring of vessel traffic is essential to navigate safely, as it allows for timely responses to changes in the environment. Reporting potential risks promptly ensures that other operators are aware of hazards that could affect safe navigation, maintaining overall safety in shared waters. Maintaining a close lookout is vital to spotting potential collisions or obstacles early enough to take corrective action. Hence, ignoring smaller crafts significantly increases the risk of accidents and undermines the principles of safe navigation in congested areas.
