What does a power vessel making way indicate in terms of sound signals?

When a power vessel is making way through the water, it indicates that the vessel is under its own propulsion and is moving. According to the COLREGs, there is no requirement for a sound signal to be made when a power-driven vessel is actively in motion. This is grounded in the rules that differentiate between vessels at anchor, vessels at risk of collision, and those that are maneuvering.

In some situations, if the vessel were at anchor or if certain safety circumstances arise (for example, when a vessel is restricted in its ability to maneuver), specific sound signals would be necessary. However, while the vessel is making way, it is not obligated to signal its movement with sound.

A specific sequence of bells, five short blasts, or the rapid ringing of a bell pertain to different scenarios or requirements under the COLREGs. These are applied in situations like signaling intentions or warning others of potential danger but do not apply when a power vessel is simply moving through the water. Therefore, the correct understanding is that no sound signal is required when a power vessel is actively making way.
