How does a pilot vessel indicate its identity?

A pilot vessel indicates its identity by sounding three short blasts on its horn or whistle. This signaling is crucial as it communicates to other vessels that the pilot vessel is in operation and likely in the process of embarking or disembarking a pilot. This established sound signal is important for maintaining safety and awareness on the water, as it helps distinguish the pilot vessel from other types of vessels that may be present in the vicinity. The specific signal helps other vessels understand they should give way or be cautious around the pilot vessel, as it is involved in the critical operation of directing larger ships safely through a harbor or channel. Understanding this signaling is vital for all mariners to ensure safe navigation when there are pilot vessels in the area.
