What do two short horn blasts meet from another vessel?

Two short horn blasts from another vessel typically indicate that the vessel is intending to maneuver, such as passing or overtaking. This signal is part of the International Regulations for Preventing Collisions at Sea (COLREGs) and is used to communicate intentions to nearby vessels. It is important for maintaining safe navigation and preventing collisions. Always be aware of the context and surrounding traffic when hearing these signals.
