What is the sound signal for a small vessel aground?

The sound signal for a small vessel aground is designed to alert other vessels to its situation. The signal consists of one blast every two minutes. This particular sound pattern is standardized to improve safety in navigation, allowing nearby vessels to identify that the aground vessel may require assistance or be in danger of collision.

When a vessel is aground, it is important to convey its status effectively to prevent accidents. The one blast every two minutes is a recognized and clear communication method within maritime regulations. Other signals, such as more frequent blasts or different patterns, may indicate different situations, such as a vessel signaling that it is underway or in distress. Therefore, the choice of one blast every two minutes specifically fits the need to communicate to others that a small vessel is aground, allowing for appropriate responses from nearby traffic.
