What indicates a vessel nearing a bend?

The correct signal indicating a vessel nearing a bend is two short blasts followed by one long blast. This combination is designed to communicate the vessel's intention to other nearby vessels, particularly in confined waters or areas where visibility may be restricted. The two short blasts convey the message that the vessel is making a turn to starboard (right), while the long blast that follows serves as a warning of its presence in the area.

The understanding of this signaling is crucial for navigational safety, particularly when vessels cannot see one another around turns or bends. This method of signaling helps prevent collisions by informing other vessels of the turning intentions and the upcoming maneuver.

Other signal options do not have the same established meanings in the context of approaching bends and turns. Clarity in communication on the water is vital, and recognizing the specific sequence of blasts is part of maintaining safety among vessels.
