What is the function of shipboard cleats?

The primary function of shipboard cleats is to secure lines and cables on deck. Cleats are critical components on a ship as they provide a reliable point for tying up various lines, such as those used for securing fenders, rigging, or positioning equipment. By allowing crew members to quickly and effectively tie ropes, cleats support safety and stability during operations on deck, preventing equipment from moving unintentionally and ensuring that everything remains secure during transit.

Other options do not accurately describe the primary role of cleats. While mooring lines, holding weapons, and navigation are essential functions in operating a vessel, they do not pertain to the specific function of cleats, which are not involved in mooring lines directly, do not secure weapons, and do not assist in navigation. Hence, understanding the role of cleats is crucial for proper deck operations and safety.
