What is a primary use of a ship's gong?

A ship's gong serves primarily as a device to produce a warning sound. This is particularly important in situations where visibility is limited, such as in fog or during nighttime operations. The sound created by the gong can alert other vessels in the vicinity of the ship’s presence, helping to prevent collisions and ensure safety on the water.

While the gong may be associated with marking time in some contexts, its main function in maritime operations is to serve as an auditory signal to convey warnings to nearby ships. Notably, gongs are used in conjunction with other sound signals to enhance communication on the water, especially under conditions where visual signals may be inadequate. The other potential uses mentioned, such as signaling foggy conditions or indicating the start of sailing, do not capture the essential purpose of the gong in maritime safety protocols.
