Which of the following actions is required to be carried out by the lookout?

The role of a lookout is crucial for ensuring the safety of a vessel and its passengers. The requirement to monitor for other vessels and obstacles at all times is fundamental to the lookout's responsibilities. This continuous vigilance helps prevent collisions and other accidents, as the lookout can give timely warnings to the operator about any potential hazards in the waterway.

Maintaining an ongoing watch allows the lookout to observe changes in the environment, such as approaching vessels or navigational challenges, and ensures that the boat can navigate safely. This proactive approach is essential for effective safety management on the water, contributing to the overall awareness needed to address any complications that may arise during operation.

In contrast, the other actions listed are either insufficient or not aligned with the primary responsibilities of a lookout. For instance, limiting the watch to bad weather or resting every 30 minutes would undermine safety by reducing the lookout’s focus on potential dangers. Monitoring passengers is important, but it does not fulfill the essential duty of being vigilant for surrounding vessels and obstacles.
