When is a outlook on a vessel required?

An outlook on a vessel is required when navigating in areas where visibility is limited, such as in fog, heavy rain, or at night. It is also necessary when maneuvering in congested waterways or when approaching hazards. The lookout ensures safety by monitoring the surroundings and providing timely warnings to the crew about potential dangers. This practice is mandated by maritime regulations to prevent collisions and ensure safe navigation.
