Which sound signal indicates your intention to overtake another vessel?

The sound signal that indicates your intention to overtake another vessel is one short blast. This specific signal is recognized internationally in maritime navigation and is an essential part of maintaining safety on the water. When you sound one short blast, you are communicating to the other vessel that you plan to pass them on their port side, which is critical for coordination between vessels to avoid collisions.

Understanding the context of sound signals is vital for safe boating. For instance, the other options correspond to different maneuvers: two short blasts indicate a desire to pass on the starboard side, one long blast signals your presence in restricted visibility, and three short blasts signify that your vessel is reversing. Each of these signals serves a unique purpose, and knowing them helps ensure effective communication on the water.
