For compartment labeling, what does the last digit indicate about the compartments?

The last digit in compartment labeling typically indicates the number of compartments off the centerline of the ship. This system helps to identify the exact position of a compartment within the ship's overall layout. For example, if a compartment is labeled with a last digit of '3', it signifies that the compartment is the third one away from the ship's centerline. This method of labeling enhances navigation and organization aboard the ship, facilitating quick identification of compartments during operations and inspections. Understanding this numbering system is essential for effective communication and safety onboard.
