Who is responsible for making reports to the Bridge regarding chain markings passing the brake?

The Petty Officer in Charge (POIC) is the individual responsible for making reports to the Bridge concerning chain markings that pass the brake. This role involves overseeing the operations on the deck and ensuring that all relevant activities, including the monitoring of chain markings, are accurately reported. The POIC plays a crucial part in maintaining communication with the Bridge, where vital decisions are made about the vessel's operations.

In contrast, while roles such as the Navigator, Chief Engineer, and First Mate are essential for the overall operation and navigation of the ship, they do not specifically focus on the details of chain markings as their primary responsibility. Instead, each of these roles has distinct functions within the crew's hierarchy and tasks, emphasizing the specialized nature of the POIC's duties in this context.
