Which role is focused on the maintenance and operation of seamanship equipment and line lockers?

The First Lieutenant (1st LT) is primarily responsible for the maintenance and operation of seamanship equipment and line lockers on a Navy ship. This role encompasses overseeing deck operations, leading the deck department, and ensuring that all necessary seamanship equipment, such as lines, rigging, and associated gear, is in good working order. The 1st LT also plays a crucial role in ensuring that the ship can effectively perform maneuvers, docking, and anchoring procedures, thereby ensuring the safety and efficiency of operations on deck.

The Chief Engineer (CHENG) focuses on the engineering department, managing the ship's propulsion and power generation systems, while the Supply Officer (SUPPO) is responsible for logistics and procurement of materials and supplies. The Food Service Officer (FSO) oversees food service operations and meal preparation for the crew. Each of these roles is critical to the ship's overall functionality, but they do not directly manage the equipment and operations specific to seamanship, which is the primary focus of the First Lieutenant.
