What does the 3rd Substitute look like?

The 3rd Substitute is represented by a white triangular pennant with a black stripe. This specific design is used in maritime signaling to indicate that the ship is in a state of readiness, specifically related to the need for a substitute or replacement.

Understanding the visual characteristics of the 3rd Substitute is important for proper identification and communication in maritime operations, especially for those in roles like the Gangway Petty Officer of the Watch, where clarity and adherence to signal protocols are crucial. This pennant helps communicate important information quickly and effectively, allowing for efficient operations on board and maintaining safety during docking and undocking procedures.

The other options represent different signals not associated with the 3rd Substitute. Each maritime signal has a specific purpose and meaning, which is essential for seamless interactions between vessels and port facilities.
