Which color stripe indicates saltwater coaming?

The correct answer indicates that the color stripe representing saltwater coaming is an 18" red stripe with yellow 3" lettering. This identification system is crucial for safety and operations involving various types of water and the handling of equipment and personnel in those environments. The red color is often associated with warning or caution, which aligns with the need to highlight areas that might be hazardous due to saltwater exposure.

Using a contrasting yellow for the lettering further enhances visibility and ensures that operators and personnel can quickly identify critical safety information. This color combination is specifically designated to prevent confusion with other types of coaming stripes, which use different colors for freshwater or other classifications, thus maintaining a clear and effective labeling system across naval operations.
