What does one prolonged blast plus two short blasts indicate?

The signal of one prolonged blast followed by two short blasts is significant in maritime communication, especially in the context of sound signals used by vessels. This particular combination is universally understood as an intention to pass another vessel, specifically indicating the desire to pass on the starboard (right) side.

This established signaling is crucial for maintaining safety on the waters, providing clear communication between boats to avoid collisions or misunderstandings. When operating in confined waters or areas of potential congestion, these signals are vital for ensuring that other vessels are aware of your intentions.

Understanding the correct usage of sound signals, like this one, is key for anyone participating in boating activities, and knowing the implications of these signals helps in navigating safely among other vessels. Therefore, the defined meaning behind this specific sequence of blasts centers on the intention to maneuver in relation to nearby vessels.
