What signal calls all personnel attached to the ship to return?

The signal that calls all personnel attached to the ship to return is represented by the flag known as "Papa." This signal is crucial for ensuring that all personnel, whether on duty or off, know that it is time to return to the ship. In maritime operations, effective communication is essential for safety and coordination, and the use of signal flags is a traditional means of conveying important messages visually.

"Papa" in the International Code of Signals specifically means "All personnel return to ship," which makes it the appropriate choice for this context. Each signal in the code has specific meanings, and recognizing them is vital for maintaining operational readiness and safety at sea. Understanding how to interpret these signals is a key aspect of a Boatswain's Mate's responsibilities, especially when managing crew movements and ensuring everyone is accounted for during operations.
